The present invention relates to a flushing mechanism for flushing tank, in particular for the flush-water tank double action.

There are many types of flushing mechanisms double-acting for selective release of the water or part thereof, located in the flush tank.

For example, the famous flushing mechanism in which the shutter rises from his seat slide driven actuator, the valve under the influence of gravity down to the closed position and a full flush can be achieved using a float which acts on the slider for the delayed return of the shutter to the closed position.

In the known flushing mechanisms dual action breakage occur due to the different pressure applied by the user to the control buttons of the actuator. In particular, the excessive pressure exerted by the user on the button partial flush, can lead to excessive lifting of the slide, which will lead to a full, not partial flushing.

Moreover, in the case of flush mechanisms, equipped with a mechanism height adjustment (height adjustment mechanism under vats of different sizes), the accuracy with which such a mechanism can be adjusted, can deteriorate due to clearances and manufacturing tolerances of the various parts of the adjusting mechanism, in h the particular slider, the retaining bolt.

The technical result of the present invention is to provide a flushing mechanism for flushing tank, in particular the flush-water tank dual action intended to eliminate the above mentioned disadvantages and which, in particular, works effectively in any operational condition.

Another technical result of the present invention is to provide a flushing mechanism which is easily and accurately adapts to flush each jaw-whisker having a different height.

This is due to the fact that in a flushing mechanism for flushing tank, in particular for the flush-water tank dual action containing the support structure, the valve is controlled by a slider configured to move along an axis passing inside the structure, and an actuator for driving the slider, the slider includes two tubular elements, one of which is inserted into the other and which are connected so that they can move relative to each other along the specified axis with a predetermined axial clearance.

A flushing mechanism of the present invention prevents malfunction due to excessive pressure exerted by the user, and, in particular, prevents the inadvertent inclusion of undesirable modes of flushing, thereby ensuring efficient operation in any condition.

Moreover, Kamenny mechanism to adjust the height of the flush mechanism provides an opt clearances and manufacturing tolerances of the various parts, providing efficient and accurate adjustment.

The ring 22 includes a side wall 33, essentially surrounding the threads 22, and two slots 34 for placement of the uprights 26. The ring support ring lever 35, hinged and mounted on the Central wall 33, and the lever 35 is fitted in diametrically opposite positions of the dog 36 held by the spring 37 in the engaged position, in which it comes in an axial direction on an edge 21 of the float 20 to prevent upward axial movement of the float 20, and the ring 38 to release the float 20 having an elongated groove 39 located parallel to the axis A.

Valve 3 includes a bolt 40 mounted on the slide 4 and interacts with a sealing seat 13.

The slider 4 includes two tubular element 41, 42 along the axis And inserted one into another and configured to move relative to each other along the axis A.

The tubular element 41 is essentially a cylindrical tube which also acts as an overflow, and a tubular element 42 having aetsa essentially cylindrical sleeve, installed radially loosely on the outer surface of the tube 41 with the free sliding of the tube 41 along the axis A.

As shown in figure 3, the tube 41 contains the lower portion 43, is placed inside the guide 18, the intermediate section 44, restricted facing each other, the annular ledges 45, 46, and segmented upper portion 47 extending from the Cup 10.

On the lower end of the segment 43 is selected, the shutter 40 and the longitudinal protrusions 48 parallel to the axis and protruding in the radial direction from the outer side surface 43 for engagement with the corresponding grooves 49, made in the inner side surface of the guide 18 so that the section 43 (fixed from rotation within the guide 18) has the ability to move inside the guide 18 along axis A.

Section 47 is defined by a sequence of rings 50, defined by many parallel and passing around the circumference of the slots 51, and has a longitudinal ribs 52, which is parallel to the axis and protruding radially from the outer side surface section 47 for engagement with the corresponding grooves 53, fulfilled in the inner side surface of the sleeve 42, and to determine the locking means to prevent rotation of the tube 41 and the sleeve 42 relative to each other and connecting tube 41 and Ulku 42 in the angular direction fixed relative to each other.

The sleeve 42 includes an annular seat 54 located at the lower end of the sleeve 42 and formed by two parallel belts 55, and the upper portion 56 with an external thread having a step P2. The upper end of the segment 56 supports the drive element 57 connected to the actuator 5.

The drive element 57 includes a ring 58 with an inner thread screwed on the section 56 and the hook 59, protruding radially outward from the ring 58.

The slider 4 has a connector 60 for connecting tubes 41 and sleeve 42 axially and fixed relative to each other with a predetermined axial clearance, when the slider 4 is raised actuator 5, and to limit axial movement between the tube 41 and the sleeve 42 along axis a to a predetermined stroke in the axial direction.

The connecting element 60 is mounted on the sleeve 42 and, as shown in figure 4 and 5, includes a radially open annular body 61 having an elastic opening 62 that allows you to insert snap ring saddle 54. The annular body 61 has a lower edge 63, which communicates axially with the ledge 46; and located around the circumference of the projection 64, which communicates axially with the thrust element, limited ledge 45. The distance between the ledges 45, 46 exceeds the distance between the edge 63 and the guide 64 and determines the allowable value of the ode in the axial direction of the tubular elements 41 and 42.

The connecting element 60 also contains an Appendix 65, which protrudes radially outward from the annular body 61, is located diametrically opposite the hole 62 and inserted into the groove 59 for engagement with the shackle 38.

As shown in figures 1 and 2, the actuating device 5 contains two buttons 71, 72 acting on the piston 73, the guide 74, secured to the cross member 27 and within which the piston 73 is moved along the axis A, and the transmission 75.

Buttons 71, 72 modes include a partial flush and a full flush respectively, and placed and moved in the respective seats, providing a different amount of axial movement of the buttons 71, 72. Both buttons 71, 72 act on the piston 73 to move it inside the guide 74, but the stroke of the piston 73 under the influence of the buttons 71 a partial flush is shorter than under the influence of buttons 72 full flush.

Transmission 75 contains essentially rectangular lever 76 is pivotally mounted on the studs 29 around the axis and having a ring 77 and the lever 78, pivotally mounted on the lever 78 to rotate about the axis that is parallel to the axis, and having element 79 that communicates with the lower end of the piston 73.

With an earring 77 concatenated hook 59 Pref the underwater element 57 so, that the movement of the lever 76 is transmitted to the drive element 57 and Vice versa.

The height of the structure 2 is regulated by the rotation of the Cup 10 with respect to the frame 11 by threaded connection between the Cup 10 and the frame 11. Rotation of the Cup 10 with respect to the frame 11 also causes rotation of the threaded section 56 of the slider 1 relative to the drive element 57 and thereby to change the provisions of section 56 relative to the drive element 57.

After the adjustment section 47 of the tube 41 and section 56 of the sleeve 42, the protruding relative to the drive element 57 can be cut off.

Thread 22 of the Cup 10 and the threaded section 56 of the slide 4 have the same direction and can have the same or slightly different from each other step, with any defects caused by the difference in step compensates axial clearance between the tubular elements 41, 42.

When used in practice, the mechanism is actuated buttons 71 or 72.

When the button 71, the lever 78 goes down and the lever 76 is rotated around the axis In order to raise the hook 59, the drive element 57 and, consequently, the slider 4. More specifically, the drive element 57 lifts up the sleeve 42, the connecting member 60 and, finally, the tube 41 with the bolt 40, thereby opening the valve 3. The progress of the sleeve 42 is dependent upon the angle is rotated, the lever 76, and the progress of the button 71, and the progress of the button 71 is such that the Appendix 65 slides in the groove 39, without entering into contact with the ring 38, so that the lever 35 remains stationary and the float 20 remains fixed in the axial direction by the pawl 36 and the slider 4 moves downward under the influence of gravity, closing the valve 3, when not in connection with the float 20, which results in a partial flush.

Similarly, when the button 72, the lever 78 goes down, and the lever 76 is rotated around the axis 76, lifting hook 59, the actuator 57, the sleeve 42, the connecting member 60 and, finally, the tube 41. Move buttons 72, however, exceeds the stroke of the button 71, therefore, the Appendix 65 comes in a groove 39 in contact with the ring 38, thereby turning the lever 35. The lever 35 causes the dog 36 releases the float 20, which rises under the influence of hydrostatic forces, and when the slider 4 is lowered under the influence of gravity to close the valve 3, the edge 63 of the connecting element 60 is lowered to the edge 21 of the float 20, thereby connecting the slider 4' and the float 20 and restraining the lowering of the slide 4, which results in a complete washout.
