RESTRICTOR VALVE WITH MEMBRANE VALVES FOR WORKING FLUID PRESSURE CONTROL IN VEHICLE ANTISKID SYSTEM BRAKE WITH VALVE SEAT PERMANENTLY INTEGRATED WITH VALVE BODY FROM POLYMER MATERIAL Russian patent published in 2014 - IPC B60T8/36 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly to working pressure control valve in brake system. Restrictor valve body accommodates at least two membrane valve with spring-loaded membranes. Besides, electromagnetic control valve 15a, 15b for pre-control over membrane valves is arranged therein to receive control pulses from electronic control unit. Seats 30a, 30b of valves 15a, 15b are integrated with the body composed of a single mid plate 24 moulded from polymer material. Plate 24 is arranged between body element 17 with holes for membrane valves membranes and other body element 33 with structural components of valves 15a, 15b except for seats 301, 30b of valves 14a, 15b made in plate 24. Said body consists of body element 17, single mid plate 14 and body element 33. Body element 33 is made by injection moulding of polymer material with solenoid coils of valves 15a, 15b built therein.

EFFECT: perfected design, simple production and mounting.
