00 00 The invention relates to devices for volumetric doses {of various pasty materials. A device for dispensing viscous materials is known, which contains a material hopper, a measuring cylinder connected to it with a dovfusennye psmeshennom placed in it, which is connected to the shaft of a power cylinder, and means to change the value of the dose, which is in the form of a tube, At our on the rod of the power cylinder Clj. A device for volumetric dosing of viscous materials is known, comprising a housing, a container with inlet and outlet pipes with installed flaps in the valves, a dosage {piston connected to the cylinder of the power cylinder, and means for changing the value of the dova, made in the form of a screw limiter and regulator) of vegetable nuts C23. The disadvantages of the known devices are the non-milling of the remote value of the dispensed dose and the large overall dimensions. This goal is achieved by the fact that in a device for volumetric dosing of pasty materials, comprising a housing, a container with inlet and outlet pipes with installed flaps, a single piston, connected to the piston rod of the power cylinder and means for varying the value of the output dose, the ram will disperse: inside the dosage of the piston, the "means of changing the value of the delivered dose is enhanced in the form of autonomy of the controlled stroke points of the diverging piston which include a connection with the external The pneumatic actuator rods (installed with the possibility of translational and rotational movement in the pipes, fixed on the housing, installed inside the metering piston parallel to the power cylinder and equipped with screw grooves at different heights, in which the stop plates 1 mounted in the rods Fig. 1 schematically shows a device for volumetric dosing of pasty materials, and Fig. 2 shows a design of a stroke limiter for a metering piston; in fig. 3 - limiter of the metering piston range, top view. A device for volumetric dosing of pasty materials, housing 1, container 2 with inlet and outlet connections with valves 3 and 4 installed on them, respectively, metering valve 5 connected to rod 6 of the power cylinder 7, and means for changing the value of the metering dose The latter include rods 9 connected with an additional pneumatic actuator 8, installed with the possibility of translational and rotational movement in pipes 1O, equipped with various grooves 11, 11 placed with the POSSIBILITY of movement are thrust pins 12 fixed in the rods 9. The power cylinder 7 and the pipes 10 are fixed on the housing I and are located inside the metering piston 5, in the bottom bottom of which there are equal holes for them. The upper part and the actuating piston 5 are sealed in 1 with one ring 13. Capacity 2 with an abgen with an adjustable stop 14 for marking the outflow of the largest dose. Power shchitsdr 7 connected by pipelines. 15 c 16 with spool 17 and pressure switch; H1c 18 and 19i. The spool 17 is equipped with 1 2O and H1 electrolyte, connected to pressure switches 18 and 19, Number of stroke limiters and piston 6 O1 will determine the number of specific values of doses that are device, / ..,.; . , The device works as follows. ; .-. ,, . In the initial position, the fan 3 is iqpbiT, and vent1 {el 4 is closed, electromagnets 20 and 21 of the spool 17 are de-energized Stock 6 of the power cylinder 7, and with it the metering plate 5 is in its lowest position. The power cylinder 7 is completely filled with rb1 working fluid. Excessive pressure in the relay 18 and 19, as well as in the pneumatic 8 oiv is absent. 9 are stitched, and their fingers 12 are located on the lower edges of the screw grooves 11. The container 2 is completely ipol on the material to be dosed. The user from the control panel (not shown) makes the selection of the dose required by him. The valve 3 automatically closes, opens the valve of the pneumatic module 8 corresponding to the selected dose, which pushes the rod 9. Finger 12, slide

Turn on the slot 11, rotate to the 1st position:

Pressing the control button of the electromagnet 21 of the anvil 17 turns on the rod 6 of the piston from the left cylinder 7 dp of the selected distance, it turns on. The bearing 4, the dosing plunger 5 starts moving up to the stop “h Bottom bottom” through the thumb 12 of the rod 9 to the upper end of the groove 11 of the pipe 1O. At the same time 1FOISKHOD1P

A sharp increase in pressure in the relay 19, which disconnects the electromagnet 21 of the petrol 17, closes the valve 4, turns on the valve 3 and turns on the electromagnet 20 of the valve 17. Processes o6puiv. The movement of the rod 6 of the power centerpiece 7 and the metering plunger 5. The material being fed enters the tank 2 "i.

The proposed device allows for remote control of remote access to the vehicle.
