The electromagnets 17 release the rod 13 and it lowers in the vertical guides 72 until its protrusion 14 contacts the stop 15 on the float. Then the electromagnets again fix the bar. When you press the na1 button, the dose is dispensed at the command of the control unit, the valve 3 opens and the liquid from the feed tank 2 is dispensed into the receiving vessel 9. As it

filling, the float 7 is immersed in the liquid until the stop 15 interacts with the sensor 16. From which a signal is received to close the valve 3 and unblock the shutter 11. After that, the shutter can be opened and removed in the receiving vessel 9. The float with the rod returns to its original position. The shutter closes and locks. 2 h. item f-ly, 1 ill.

The invention relates to dispensing devices and is intended for use in automatic devices for dispensing various liquids having a significant coefficient of thermal expansion, in particular, oils.

The purpose of the invention is to increase the reliability of dosing.

The drawing shows the proposed device for dispensing a liquid.

The device comprises a housing 1, a coin mechanism disposed therein (not shown), a feed tank 2 with an outlet opening equipped with a valve 3. connected to a control side (not shown) located in the box 4. A dispensing mechanism is installed under the outlet opening made in the form of a container 5 with a working fluid, and in which a float 7 is placed in the guides 6, the upper part of which is made in the form of a support, for example a plate 8, for the receiving vessel 9. In the case 1 for the latter a window 10 is made. shutter 11.

The registration unit of the metering mechanism is made as installed in the vertical guides 12 of the rod 13 with a protrusion 14 located above the stop 15 arranged on the float. The sensor 16 of the end position of the dose mounted on the rod under the stop on the float is made adjustable in the height of the rod, equipped with locks of its position, for example electromagnets 17. A movable shutter 11 1 is filled with a handle 18 and provided with a knockout unit in the form of a spring-loaded gripper 19 and an electromagnet 20. 8 the upper position of the curtains and interacts with a focus 21. Sensors end position dose. the coin mechanism, the valve, the latches and the locking assembly are connected to the control unit.

The device works as follows.

When a coin is thrown into a coin mechanism (not shown) cpa6aTb) saet

an electromagnet 20, releasing the shutter 22 and allowing it to be freely lifted by the handle 18 and secured with an upper 21 in the upper position (the position of the shutter is shown in dotted lines in the drawing).

Then, the receiving vessel 9 is installed on the plate 8 and the shutter 11 is lowered, which is blocked at the same time. Under the action of the mass of the vessel 9, the float 7 is immersed in the working fluid. At the same time, the electromagnets 17 release the bar 13. and it lowers along the guides 12 until the protrusion 14 comes into contact with the stop 15 on the float 7. Then the electromagnets 17 again fix the bar 13. The device is in the ready position for dispensing the dose. When you press the dose out button (not shown), at the command of the controls, the discharge valve 3 opens, and the metered liquid from the supply tank 2 begins to drain into the receiving vessel 9. As the vessel 9 is filled, it is lowered and, accordingly, the float is immersed. 7 into the working fluid until the contact stops 15

the sensor 16, the position of which on the rod 13 relative to the protrusion 14 is adjusted in accordance with a given dose mass. The sensor 16 receives a signal to close the valve 3 and unblock the shutter, which can then be opened and removed from the filled receiving vessel 9.

The float 7 with the rod 13 returns to its original position. Then the shutter 11 is closed and locked. The device is ready for the next cycle of operation.
