摘要： A control valve of a hydraulic brake booster for use in a brake system. The control valve is characterized by a shuttle member having a stem on a first end and an annular projection on a second end. The stem has an annular surface thereon that is matched with an orifice from an supply chamber such that metered pressurized fluid is uniformly presented to an actuation chamber to effect a brake application while the annular projection is matched with a flange on an actuator piston such that the pressurized fluid present in the actuation chamber is uniformly metered to a reservoir.

摘要： A reaction arrangement for a brake booster having a control valve selectively activated by a manual input force or an electromagnetic force to allow air to create a pressure differential with vacuum and produce an output force that is transmitted through an output member in effecting a brake application. The output member encounters resistance during the brake application that is defined by a reaction force transmitted through a disc. A first shaft engages the disc and communicates the reaction force to balance the manual input force while a second shaft engages the disc and communicates the reaction force to balance the electronic force such that a resulting output force to effect a brake application is similar whether initiated by an operator or an electronic control unit.

摘要： A control valve for a brake booster having a first member with a first bore, a second member located in the first bore and having a second bore, a plunger located in the second bore and connected to an input member. A gear fixed to the second member with teeth that engage a first rack retained in the first body and a stationary rack within the brake booster. A force applied to the input member controls the development of a pressure differential that moves a wall during a brake application. Movement of the wall causes a rotative torque to be transmitted from the first rack into teeth such that the gear moves with respect to the second rack and the second body to separates from the first body and as a result the travel of input member is less than the travel of the wall during a brake application.

摘要： A control valve (10) having a plunger (64) with a stem having a flange defined by a first diameter (66) loosely located in a first diameter (58) of a bearing (50) and a second diameter (68) sealingly located in a second diameter (56) of the bearing (50). A space between the flange and the bearing (50) defining a dampening chamber (82) such that on movement of plunger (64) toward an actuation chamber (54), fluid is drawing through a controlled flow path (x) into the dampening chamber (82). Under certain operational conditions, fluid pressure in the actuation chamber (54) maybe subjected to oscillation and the fluid in the dampening chamber (82) cancels the effect to the oscillation such that plunger (64) remains in a substantially stationary position corresponding to an input force applied thereto to effect a brake application.
