Hydraulic pressure regulator with overpressure attenuator - has spring loaded ball bearing type anti-return valve held at one end of hollow slide

摘要

The hydraulic pressure regulator has a movable hollow slide (10) which is held at one end by a calibration spring (12). At the other end of the slide it receives the operating pressure(7) via an anti-return valve. The anti-return valve consists of a ball-bearing (21) acting against a spring (22) resting against the circular orifice situated at the rear of the slide. The slide (10) moves in a fixed sleeve (8) to which is fixed the retaining system for the spring pressing against the ball-bearing of the anti-return valve.
