HYDRAULIC PRESSURE-OPERATED STYLE SHIELDING VALVE AND HYDRAULIC PRESSURE TYPE VEHICLE BRAKING DEVICE

摘要

PURPOSE: The hydraulic pressure type shielding valve is provided to enable to use as an inhaling valve by being arranged between a main braking cylinder and a supply pump of ABS for vehicle. CONSTITUTION: The hydraulic pressure type shielding valve having a valve closing member for controlling the opening position and the closing position and also having an operating member for affecting pressure shock. When the operating member(26) affects the shock over the pressure of transformed pressure, it is transformed by the operating member(26), has a locking member(34) where the closing member(20) is operated. The locking member(34) has a reverse spring for oppressing the valve member(20) to the initial position. The operating member(26) is formed as a ring shape and is moved to the axis direction in the valve chamber(14) for affecting the pressure shock.
