Pressure control valve for vehicle anti-locking braking system - has non-return valve providing shorter route to vent point for reverse press medium flow

摘要

The press control valve has a 2-part outlet chamber (3, 7) for the press medium incorporating an electromagnetic outlet valve (9, 10) for coupling to a vent point (17) operated by a piston acted on by the press within a control chamber in the closed position of the valve (9, 10). The press medium from the press source is supplied via an electromagnetic inlet valve (47, 2) with a membrane (43) acting as the operating piston, with a further valve (50) lying behind the inlet valve (47, 2) in the direction of the press. medium outlet (4) and closing in the opposite direction. The further valve (50) is provided by a non-return valve. ADVANTAGE - Reduced vent time.
