ROTARY MULTICHANNEL DISPENSER OF FLUIDS AND SEMI-FLUIDS Russian patent published in 2013 - IPC B65B3/00 

FIELD: transport.

SUBSTANCE: invention relates to dispensers and may be used if lacking fluids and semi-fluids in food industry, chemical industry, etc. Proposed device comprises pressure pipeline, product portion discharge nozzles 11, flow shells 2 accommodating floating piston 3 dividing shell 2 into two chambers 4, 5, case with channels 13, 14 communicating said chambers with pressure pipeline and nozzle 11, and mechanism to communicate said chambers in turns said to pipeline and nozzle. Besides, device comprises rotor 1 supporting k≥1 shells 2 with their chamber 4, 5 communicating with holes 6, 7 made on rotor ends Said shells stay in contact with case formed by hollow shaft 8 with its inner bore communicated with said pipeline, and two flanges 9, 10 End of every flange in contact with end of rotor 1 includes even number n ≥ k of holes regularly arranged over circumference of channels 13, 14 communicated with bore of shaft 8 and nozzle 11. Aforesaid mechanism to communicate said chambers in turns said to pipeline and nozzle is composed of a drive turning rotor through angle of 2π/k.

EFFECT: simplified design, smaller sizes, lower costs
