VOLUMETRIC PROPORTIONER OF LIQUIDS WITH WEIGHT CONTROL Russian patent published in 2009 - IPC G01F13/00 G01G13/04 

FIELD: physics, measurements.

SUBSTANCE: invention relates to batching liquids, mainly viscous and pastelike, including explosive, used in manufacture of mixed solid propellants. The proposed volumetric liquid proportioner with weight control consists of a proportioning cylinder with the piston and rod, distributing device with the valves of batching a medium portion and letting it out, and a portion let-out drive. In compliance with this invention, the proportioning cylinder incorporates a weight lever with force-measuring pickup, proportioning cylinder rod stroke control pickup and driven receiving bin. The distributing device comprises a hollow-stem driven shut-off valve, a plug arranged inside the shut-off valve and a driven pusher to move the said plug. The aforesaid pusher is fitted inside the hollow stem to axially move therein.

EFFECT: increase in accuracy.
