FLOW REGULATOR Russian patent published in 2007 - IPC F15B13/07 

FIELD: hydraulic systems.

SUBSTANCE: proposed flow regulator is designed for hydraulic systems of movable pumping stations or different road-building machines to control flow rate of working liquid delivered to one or two consumers operating simultaneously , for instance, hand hydraulic tools. Flow regulator is provided with system dividing flow for two consumers consisting of two interconnected velocity regulators, each being made in form of controlled restrictor and reducing valve with spring-loaded spool installed in succession between pressure and working lines. Spool is located in direction of opening by pressure acting at outlet of controlled restrictor, and in direction of closing, by pressure in working line of most loaded consumer. Spring space of reducing valves of both regulators are interconnected and are coupled with working lines through check valves.

EFFECT: enlarged capabilities.
