The purpose of the invention is the provision of proportionality payment procedure for water consumed water volume.

This is achieved by the automatic shower installation, consisting of a mixing chamber, inside which are two of the locking member, one of which is cone-shaped with the possibility of reciprocating motion and contact with one side of the tapered seat, containing inlet and outlet channels, and on the other hand - with the other locking body mounted to rotate its shaft and pressing to the edge of the overflow drain, and a rotary shaft connected with the lever of inclusion, and at the end of the lever for engaging the elastic hinge fixed discharge tray located at the end of the vertical channel transfer counter, moreover, in the lower part of the vertical channel at the wall opposite the mixing chamber, the indentation.

The novelty of the present invention in comparison with the prototype is that instead of manually enable the mechanism to automatically turn on a special token that provides a controlled release of water to the consumer, the proportional value is omitted in particularistically shower installation of signs, specified in the restrictive and distinctive parts of the claims was not detected. Then as soon as their joint application leads to the achievement of this goal. This suggests that the claimed technical solution that contains all the given set of features, meets the criterion of "substantial differences".

In Fig.1 shows the mechanisms of inclusion and mixing chamber, a longitudinal section; Fig.2, 3, 4 - species mechanism connecting the lever with sbresny tray; Fig.5 is a view along arrow b of Fig.2.

Automatic shower set consists of the mixing chamber 1, the tapered seat 2 which is made of the inlet 3, 4 and outlet 5 channels. In the mixing chamber is placed a stop valve 6 cone shape with the possibility of reciprocating motion. To narrow the base of the locking member 6 is rigidly attached to the rod 7 with the screen at the end, placed in a discharge channel 5. At the bottom of the mixing chamber 1 has a bypass hole 9, covered inside the locking body 10, is rigidly connected to the roller 11, the free end of which is placed outside, is rigidly fixed to the lever 12 include with the possibility of free rotation until it stops 13 around the axis of the roller 11 and knymi channel 15. At the top of the vertical channel 15 is receiving hole 16 for a counter 14. The end of lever 12 axis 17 is connected to sbresny tray 18 with the possibility of free rotation, the axis 17 is wound the spring 19, the ends secured in holes formed in the lever 12 on and the discharge tray 18. The spring 19 holds the ends of the lever 12 and the discharge tray 18 are pressed together position. At the other end of lever 12 enable the wall 20 of the vertical channel 15 angled 90aboutthe indentation 21 with the ability to accommodate a counter 14. At the bottom of the vertical channel 15 is connected to the camera 22, the top of which is placed a lever 12 inclusion, and the lower part serves as retinoscopes.

Automatic shower unit operates as follows.

For receiving water treatments under the shower, you must purchase a sufficient number of coins 14. To start the shower installation token 14 should be lowered into the receiving hole 16, and then, falling down the vertical channel 15, the counter 14 strikes the end of lever 12 to turn on, thus reducing the contact force of the locking member 10 to the edge of the hole 9, rotates the system stop valve - lever 12 enable - discharge tray 18 in a clockwise stre will make a movement to the right along its inclined plane, on sprocname tray 18 and will take an extreme position on its extreme edge, touching the side wall 20 under the indentation 21.

From the equation of the moments of the forces with respect to the roller 11 can determine the necessary force of impact of the counter 14 and the arm 12 enable to overcome the pressing force of the locking member 10 to the edge of the overflow opening 9, namely

Gbeats= , (1) where P is the pressing force of the locking member 10 to the edge of the overflow opening 9; l, l is the radius of the position of the locking body 10 and the contact point at the impact of the counter 14 and the arm 12 enable.

Assume that the water pressure in the inlet channels H = 5 m, and the diameter of the bypass hole 9dg= 8 mm, the force is R = 0,25 kg will Take l = 10 mm, L = 100 mm, then

Gbeats= = 0,025 kg=25g

The force of the blow of the coin depends on its mass and the fall height on the vertical channel 15 - Ztothat creates a certain speed counters at impact, which can be defined by the formula (1)

v= , (2) and the impact force of the counter 14 and the arm 12 of the inclusion can be defined by the formula (1)

Gbeats= (3) where m, v are respectively the mass and velocity; t is time of impact.

Suppose that the height of the drop, i.e. the height of the vertical channel 15, Zto= 0.5 m, and the duration of impact t = osti valve body 10, lever 12 enable to start the shower installation by weight quite suitable three-kopeck coin, i.e., as a token may be used coin price 3 down by the Rotation of the lever 12 and the inclusion of the locking body 10 opens the bypass hole 9, the reduced pressure in the mixing chamber 1 is almost to the level of atmospheric pressure. The water pressure in the inlet channels 3, 4 stop valve 6 is released from the conical seat 2, which will result in the admission of hot and cold water from the inlet channels 3, 4 in the discharge channel 5 and the mixing chamber 1, pushing down the locking body 6 to lock it in the lock body 10. The pressure of the water in the mixing chamber 1 stop valve 6, acting on the locking body 10 will rotate it around the axis of the roller 11 are pressed to the edge of the overflow opening 9. Simultaneously with the rotation of the locking member 10 will rotate the lever 12 included in the initial position (Fig.1). When the lever 12 included in the initial position of the discharge tray 18, based on the chip 14, a support which at this time is the indentation 21, will make a rotation around the axis 17, overcoming the resistance of the spring 19. Simultaneously with the rotation of the discharge tray will do the upward movement together with the lever 12 include, Osvoboditel. After closing the bypass hole 9 of the locking body 10 all the water will flow in the discharge channel, shower net. Screen 8 at this point will occupy a very low position, testing the effects of water flow, will create sufficient traction to cause upward movement of the locking body 6, the value of which is determined by the well-known formula (2)

Pt= cs , (4) where C is the coefficient of resistance of the screen; Sm- the area of the fuselage mid-section of the screen; - water density; v is the velocity of water flow.

Movement of the locking member 6 up accompanied by passage of water through the gap between his wide base and a wall of the mixing chamber 1, the flow of which can be represented in the form (2)

Q= , (5) where is the coefficient of discharge gap;3- screening area of the flow in the gap; P - pressure drop water above and below the locking body 6; - the density of water.

The differential pressure P is generated thrust Pton the screen 8, so

P = = ,

(6) whereC.about- the cross-sectional area of the large base of the locking member 6.

Put the P value from the formula (6) in formula (5), we obtain

Q=Cv (7)

The duration of the movement of the locking member 6 from the extreme bottom position to a cone cf> Formula (8) shows that the same procedure is inversely proportional to the speed of movement of water in the discharge channel.

Find the volume of water supplied by the switch in one procedure, the value of one token

W=tvOK= ,

Formula (9) shows that every time the shower installation corresponds to a constant volume of water required to water the procedure, since all the quantities involved in the right part of the formula reflect the geometric dimensions of the switch, and hydraulic constant characterizing these sizes, so

= const (10)

The duration of each procedure depends on the flow rate, namely

t = =
