The excess flow valve With diaphragm valves to control the pressure working fluid in the anti-lock braking device system of the vehicle with the valve seat, one-piece integrated into the housing element of a polymeric material

摘要

1. The restrictor valve (7) for controlling the working fluid pressure in the brake anti-lock system so that during a tendency to blockage of the individual wheels (3a, 3b; 4a, 4b) pressure of a vehicle brake actuator system is coordinated in the corresponding adaptively cylinders (6a-6d) of hydraulic brake actuator, and in one case (18) the pressure control valve (7), at least two diaphragm valves (14a, 14b), having loaded spring elements (16a, 16b) of the membrane (20a, 20b ), and that kzhe, at least one adapted to receive the electronic unit (10) controlling the control pulses of the electromagnetic control valve (15a, 15b) for pre-controlling membrane valves (14a, 14b), characterized in that at least one saddle (30a, 30b) of the valve, at least one electromagnetic control valve (15a, 15b) formed integrally with the element (24) of the casing formed from a blank made by injection molding of polymer material. ! 2. The restriction valve according to claim 1, characterized in that the element (24) the housing containing at least one seat (30a, 30b) of the valve, made of fiber-reinforced polyamide in the form of a plate. ! 3. limiting valve according to claim 1, characterized in that the element (24) of the housing is made of fiber-reinforced polyamide. ! 4. The excess flow valve according to any one of claims 1-3, characterized in that the at least one seat (30a, 30b) of the electromagnetic valve of the control valve (15a, 15b) formed conical and limits configured in the element (24) of the body central channel (32a, 32b) of the working medium.
