Next, with reference to figure 2 in more detail described drive unit 4 and unit 5 of the control.

Drive unit 4 includes a coupling 7, which is placed in the hole in the lid or in the flush tank (not shown) and which by means of the threaded protrusion 8 screw in a recessed nut (not shown). Such a coupling is known from the prior art.

Drive unit 4 has a plunger 9, which includes an axial extension 10, capable of vdvinut'sā threaded protrusion 8. In one of the embodiments, which are not shown, the plunger 9 can operate the push button, a flexible membrane or other element in the form of a cover.

The control unit 5 has a housing 11 that includes a sleeve 12 having, for example, a predominantly cylindrical shape. The sleeve 12 has a ring the tide Oh 13, protruding radially inward. Tide 13 can communicate with the annular groove 14 to provide ratcheting effect threaded protrusion 8. Thus, the connection sleeve 7 through the elastic deformation is included in the cuff 12, and then is fixed by ratcheting effect.

Inside the casing 11 is placed in the drive rod 15. The drive rod 15 has one end 15A, resting in the bottom side of the extension 10. The opposite end 15b of the drive rod 15 is a knee 16, passing in the direction of the circumference of the casing 11.

Between the bottom surface 11a of the casing 11 and the knee 16 is petal 17, forming a spring, which pushes the bar 15 and thereby the strip 10 in the direction of its initial position in which the plunger 9 extends out of the coupling 7. Petal 17 made for example of steel or plastic. In the shown embodiment, the Central portion 17A of the petal 17 based on a surge of 18 the lower surface 11a of the casing 11. One end 17b of the petal 17 rests on the knee 16. The opposite end 17c of the petal 17 rests on the knee 20 of the drive rod 21, the function of which is described in detail next.

The control unit 5 includes a support 22 for the seat 22A. Bearing 22 of the seat includes a channel 23. The channel 23 is connected with the Executive channel 24 (1) of the valve 6 of the Executive branch pipe 25, which is conventionally denoted pun is Tierno lines in figure 1. The channel 23 can communicate with paraniwin hole 26 in the bottom surface 11a of the casing 11 through the groove 27, which comes to seat 22A. Paranaue hole 26 extends, for example, in the flush tank (not shown).

Knee 16 includes a groove 28, which is located to the right of the groove 27 in which is placed a seal 29. In the initial position the petal 17 holds the knee 16 in the upper position. It obturator 29 rests in the groove 27 and blocks communication between the channel 23 and paraniwin hole 26.

Next, with reference to figure 3 in more detail the valve 6.

The valve 6 includes a housing 31 of the valve. Executive channel 24 reaches the groove 32 in the housing 31 of the valve.

The valve 6 includes the input channel 33, which is connected with means for supplying water (not shown). The valve 6 includes an output channel 34, which is connected to the chamber 69 (Fig 1) cylinder 3 by a pipe 30, which is conventionally indicated by the dotted lines in figure 1. The valve 6 includes an exhaust channel 36 that extends, for example, in the flush tank.

The groove 32 is elastic membrane 37 which separates the Executive channel 24 from the input channel 33, the output of the channel 34 and the exhaust channel 36. The membrane 37 is based on the exhaust pipe 38, which is inserted into the housing 31 of the valve. O-ring 39 provides a seal between the body 31 of the valve and exhaust Petrovka. Tube 40 is screwed on the casing 31 of the valve, allows you to hold the membrane 37 in position, clamped to an exhaust pipe 38.

Between the Executive channel 24 and the input channel 33 is a sensor 42 in a generally cylindrical shape, one end 42A which fits in the Central hole 43 in the membrane 37.

Through the sensor 42 passes a longitudinal hole 44, which does not reach the end 42A. The hole 44 at a right angle intersects with the bore 45. To the hole 45 reach two grooves 46, for example, a triangular cross-section. Thus, the channel between the grooves 46 and the membrane 37 is designed to significantly reduce the flow rate between the inlet channel 33 and the Executive channel 24.

The valve 6 includes a seal 47, made in the form of a single whole with the sensor 42. The shutter 47 is able to move in the groove 48 in the housing 31 of the valve between the first position shown in figures 1 and 3, and a second position shown in Fig. Input channel 33, the output channel 34 and the exhaust channel 36 extend into the groove 48. In the first position, the shutter 47 is based on the edge 50 of the input channel 33 and prevent the circulation of water between the inlet channel 33 and the groove 48. In it, the shutter 47 is located at a certain distance from the edge 51 of the exhaust pipe 38, and between the output channel 34 and the exhaust channel 36 possible water circulation. In the second position obturate the 47 rests on the edge 51 and prevents circulation of water between the groove 48 and the exhaust channel 36. In it, the shutter 47 is located at a certain distance from the edge 50, and between the input channel 33 and the output channel 34 possible water circulation.

Next, with reference to figure 4-6 are described in more detail mechanism 2 flushing.

The flushing mechanism 2 includes overflow pipe 53 which can move installed in the casing (not shown). On the lower end of the overflow pipe 53 rests head 54 with a flat seal around the perimeter, which forms a shut-off valve 56 that communicates with the cap 57.

When the shut-off valve 56 is located at a certain distance from the cap 57, the water from the flush-water tank flows into the bowl (not shown).

The flushing mechanism 2 includes a float 58 that is mounted on a micrometer screw 59 for precise height adjustment, which adjusts the amount of incoming water. The screw 59 includes an upper head 60, and at its lower end 59A is swivel 61 of the lever 62, the end of which, opposite the hinge connection 61, mounted to rotate about a fixed axis relative to the casing. The lever 62 has a thickness of 63, which cooperates with a Cam 64 on perelivom the pipe 53, which is described further below.

The cylinder 3 includes a housing 66 and the piston 67, which is attached to the rod 68. The housing 66 in combination with the piston 67 forms a chamber 69. Luggage 69 vkluchaetsia hole 70, which is connected with the output channel 34 of the valve 6 by a pipe 30. The rod 68 is connected with the drain 53. The piston 67 acts spring (not shown) in the direction in which the volume of the chamber 69 tends to decrease, i.e. downwards, as shown on the drawings.

Next, with reference to Fig.7 more detail the connection of the branch pipes 25 and 30. The pipes 25 and 30 are flexible pneumatic tubes. In block 5 of the control valve 6 and the cylinder 3, respectively, built-in tools that provide mechanical support and integrity of the pipes 25 and 30. Mechanical support is provided with two detachable shell 95, which capture the nozzles 25, 30, respectively. Split shell 95 include grooves 98 for fixing pipes 25, 30, respectively. Inside detachable shell 95 is placed the main part 97 of the water. O-ring seal 96 provides a seal between the nozzles 25, 30, respectively, and part 97.

The following describes the actuation mechanism 2 flush actuating device 1.

In the initial position (Fig.1-6), the plunger 9 is in its upper position, i.e. acts of the coupling 7.

In this position, the shutter 29 is pressed against the groove 27 of the blade 17 and prevents circulation of water between the channel 23 and paraniwin hole 26. Closing a diameter of, for example, about 0.6 mm To ensure hermeti the activities at the test pressure of about 16 bar lug 17 has on the obturator 29 through knee 1 pressure corresponding, for example, from 200 to 300,

In this position the water which is in the Executive branch pipe 25, which passes through the sensor 42, the pressure on the upper part of the membrane 37. Due to this, the shutter 47 is held in the first position through the sensor 42. Luggage 69 mostly empty, and the piston 67 is resiliently held in the lower position.

As a result, when the user presses on the plunger 9 to move it from that position up to the position in which the plunger is predominantly in the plane of the coupling 7 (Fig), the shutter 29 is raised and out of the groove 27 as the compression lobe 17. The shutter 29 is lifted out of the grooves, for example, approximately 1-1,5 mm In this position, the water in the Executive branch pipe 25, empties through paranaue hole 26, and the pressure on the upper part of the membrane 37 is reduced. Under the action of pressure in the inlet seal 47 and the sensor 42 are moved up in the second position of the shutter 47 (Fig). It Luggage 69 of the cylinder 3 is filled with water from the output channel 34, which receives water from the inlet channel 33. The piston 67 and the rod 68 is smoothly enter into the housing 66 of the cylinder, resulting in the overflow pipe 53 is moved upward and the valve 56 is opened. The valve 56 is separated from the saddle cap 57 in height, for example, approximately 20 m is.

At the same time, the Cam 64 moves smoothly through the thickening 63 of the lever 62, while the thickening 63 will not be under the shoulder 72, which is formed by a Cam 64 (figures 9 and 10). The float 58, which pushes the screw 59 upwards provides the tilt lever 62.

When the user releases the plunger 9, the shutter 29 begins to move under the action of the petal 17 until, until it reaches the saddle 22A. In this position, the obturator 29 rests in the groove 27 and prevents circulation of water between the channel 23 and paraniwin hole 26. The pressure of the water in the Executive branch pipe 25, is increased, which leads to deformation of the membrane 37. The shutter 47 is raised to the first position. In this position, the seal 47 prevents circulation of water between the inlet channel 33 and the output channel 34, but does not prevent the circulation of water between the output channel 34 and the exhaust channel 36. Due to this, the water in chamber 69 of the cylinder 3, arrives in wash tank. Her flow stops when the camera 69 empties, which corresponds to the lower position of the piston 67.

The float 58 overlaps the overflow pipe 53 and then opens it after lowering the water level in the tank. When the float 58 is lowered, the lever 62 is rotated. Then thickening 63 again departs from the shoulder 72, and the overflow pipe 53 is free to fall, interrupting emptying.

Thus, the button to operate the flushing mechanism 2, the user only needs to put some effort, allowing the shutter 29 to move. In this case, due to the pressure in the water system drain 53 rises. In other words, when the user applies a relatively small force to the plunger 9, due to the pressure in the water system generates greater force, allowing to operate the flushing mechanism 2. Thus, the pressure in the water system facilitates the actuation of the flushing mechanism. Due to this control device 1 makes it possible to reduce the force and stroke of the plunger 9 and simplify the transfer mechanism 2 flushing. The connection of the plunger 9 with the flushing mechanism 2 is very flexible and can have a greater length, which facilitates the installation of the actuator 1.

The stroke of the plunger 9 is, for example, approximately 1.5 mm due to the small stroke of the diameter of the plunger 9 is not required to adjust to the diameter of the hole in the lid of the tank, which is typically 40 mm due to this, you can use a flat coupling very large diameter in order to leave more space for the pins. This enables you to choose different ways to perform a node coupling the plunger. For example, the node coupling the plunger may be sealed in a flexible housing with a protrusion corresponding to the upper position of the plunger. The other is the information and communications technology is the use of flexible color keypad type keypad electronic control device.

The flushing mechanism 2 shown in figure 1-12, is the so-called dual flushing mechanism, i.e. it allows you to paragnath two different volume of water at the discretion of the user.

The plunger 9 is the so-called plunger weak flush. Drive unit 4 has a second, so-called plunger 80 strong flush, which includes an axial extension 81 capable of vdvinut'sā on the threaded projection 8.

The drive rod 21 includes one end 21A, rests on the bottom edge of the extension 81. The opposite end 21b of the drive rod includes a knee 20, which passes in the direction of the circumference of the casing 11.

The control unit 5 includes a second bearing 82 to seat a. Bearing 82 of the saddle includes a channel 83. Channel 83 is connected by the Executive branch pipe (not shown) with the Executive channel of the second valve (not shown). Channel 83 is able to communicate with paraniwin hole 84 in the bottom surface 11a of the casing 11 through the groove 85, which reaches up to the saddle a. Paranaue hole 84 extends, for example, in the flush tank.

Knee 20 includes a groove 86, which is located to the right of the groove 85 in which is placed a valve 87. In the initial position the petal 17 holds the knee 20, is pressed against the saddle a. In this position, the valve 87 is pressed against the groove 85 and blocks communication between the channel 83 and paraniwin hole 84.

Klapa is, connected with the plunger 80 strong flush, similar to the valve 6.

The flushing mechanism 2 includes a float 90 strong flushing, capable of turning about a fixed axis relative to the housing and mounted on one side, mostly diametrically opposite the float 58 weak flush relative to the overflow pipe 53. The float 90 is located below the float 58. The float 90 is thickening 91, which interacts with the Cam 92 on perelivom the pipe 53. Thickening 63 is located below the thickening 91.

The flushing mechanism 2 includes a second cylinder 93, similar to the cylinder 3. Stroke strong flushing greater than the stroke of the piston 68 weak flush, due to which the piston is strong flushing able to raise the valve 56 to a great height.

The flushing mechanism 2 is brought into action by pressing on the plunger 80 similar to actuate the flushing mechanism 2 by pressing on the plunger 9.

In this case, the thickening 91 stops under the shoulder 94 of the Cam 92, whereby the float 90 strong washout closes the overflow pipe 53. The overflow pipe 53 is moved to a higher paranaue the position that corresponds to the emptying with a strong flush. The valve 56 is separated from the saddle cap 57 in height, for example, approximately 26 mm As before, the overflow pipe 53 is opened only when the level of the water in the tank releases the float 90, which rotates and moves the thickening 91 of the Cam 92. Then the overflow pipe 53 drops sharply in the blocking position after operaniuni amount of water corresponding to strong erosion.

Other choices are possible. For example, the actuator 1 can be used to bring operaniuni single or sinks bath, washbasin, bidet or any other sanitary-technical equipment that needs to be driven mechanism operaniuni.

Although the invention is described with reference to one private option, it is in no way limited to them and includes all technical equivalents of the described means as well as their combinations if they are included in the scope of the invention.
