HYDRAULIC BRAKE BOOSTER AND VALVE MEMBERS ABSTRACT A hydraulic brake booster (10) includes a housing (12) which defines a pressure chamber (16) and a piston (18) within the housing (12) is movable in response to pressurized fluid within the pressure chamber (16) to effectuate a brake application. The piston (18) encloses a storage chamber (60) and forms a pair of passages (80, 90) communicating the storage chamber (60) with the pres- sure chamber (16). A valve member (100) is disposed within the first passage (80) in order to control commu- nication between the storage chamber (60) and pressure chamber (16). The valve member (100) permits pressurized fluid within the pressure chamber (16) to be communicated to the storage chamber (60) in order to charge the storage chamber (60). The valve member (100) also permits high pressure fluid above a predetermined pressure level within the storage chamber (60) to be communicated to the pres- sure chamber (16). The second passage (90) includes a dump/charging valve (120) which can be opened by an operator actuator (50) to permit pressurized fluid to be communicated from the pressure chamber (16) to the storage chamber (60) for charging and, when insufficient pressure is present in the pressure chamber (16), is actuated by the operator actuator (40) such that higher pressure fluid in the storage chamber (60) is dumped into the pressure chamber (16) in order to assist in the displacement of the piston (18) and to effectuate a brake application.
