The invention relates to devices for volumetric dosing, in particular to devices for dosing viscous materials.

The purpose of the invention is to simplify the design;

The installation of a container for materials with the possibility of reciprocating the movement of J, releasing the sleeve with a hollow piston at its outlet and allowing the valve to exclude the device for controlling the presence of the product. Fig. 1 shows a device for dispensing viscous materials; 5 a vertical section; FIG. 2 is the same, front view; in fig. 3 and 4 - device in operation; FIG. 5 shows section A-A in FIG. 3,

The device comprises a rack 1 on which the control lever 2 of the actuator is mounted and the guide -3 of a cylindrical shape, in which the container 4 for the dosing material with the piston 5 is pressed.

The upper end of the container 4 is hermetically sealed with a lid 6 with a fitting 7 for supplying compressed air .. At the outlet of the container, a sleeve 8 is fixed inside which is connected to control 1 (with a lever 2 there is a hollow piston 9 of the device for dispensing material. equipped with a floating valve 10. The lower part of the sleeve 8 is secured with a check valve 1 1 and a tap 12 with a tip 13j and the actuating lever 2 of the actuator moves under the influence of the copier 14.

The device works as follows. in a way.

The dosing material is loaded into the container 4; tightly closed krypika 6, through fitting 7 which

compressed air is supplied and material is pre-pressed by means of the piston 5. By acting on the control lever 2, the associated hollow piston 9 moves upwardly relative to the sleeve 8. The valve 10 opens and the material to be dosed, the passage through the piston, fills the cavity of the metering cylinder. Moves up with respect to rack 1 and capacity 4.

When lowering the lever 2 under the action of its own weight, the container 4 lowers until the tip 13 stops against the surface of the product 15. Upon further lowering of the lever 2, the piston 9 starts to move downward relative to the sleeve 8, the valve 10 closing the piston and the material is squeezed out of the cavity and through the check valve 11 , the outlet 12. and the tip 13 on the surface of the product 15, and in the absence of the product does not move the piston 9 relative to the sleeve 8 and the material remains in the cavity of the device for dispensing.
