RESTRICTOR VALVE FOR VEHICLE ABS WORKING FLUID PRESSURE CONTROL AND METHOD OF ITS FABRICATION Russian patent published in 2014 - IPC B60T8/36 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to ABS restrictor valve. First body (18) of restrictor valve has at least two membrane valves (14a, 14b) with spring-loaded (16a, 16b) membranes (20a, 20b) and at least one solenoid control valve (15a, 15b) controlled by electronic control unit to actuate said valves (14a, 14b). Surface (25) of the body (18) first element (17) has bores (19a, 19b) for membrane (20a, 20b) to be fitted therein, its edges (22a, 22b) being locked between bore edges (23a, 23b) and body (18) extra element (24). Edges (23a, 23b) are located in common plane or in parallel planes while perpendiculars (44) to edges (23a, 23b) are directed in one direction. Body extra element (24) is arranged between body first element (17) and second element (33) to receive at least one valve (15a, 15b). At least one seat (30a, 30b) of at least one valve (15a, 15b) is made at body extra element (24) facing the body second element (33) surface (43). Body second element (33) is equipped with at least one through bore (34a, 34b) to fit structural elements of valves (15a, 15b) such as armature (35a, 35b) or magnetic core (40a, 40b). Central axis (36a, 36b) of through bore (34a, 34b) is located parallel with the perpendicular to surface of edges (23a, 23b) of bores (19a, 19b) in body first element (17).

EFFECT: simple fabrication and assembly.
