ABSTRACT:
A brake booster includes a housing with an inner wall defining a pair of pressure chambers. A passage in the inner wall communicates the pressure chambers with each other and an input member is slidably disposed in one of the pressure chambers and an output member is slidably disposed in the other pressure chamber. A resilient member extends between the inner wall and the input member and substantially defines a variable orifice to control fluid communication between an inlet and a return. The return is disposed within the inner wall and the resilient member comprises a coil spring which permits fluid communication between the coils. When the input member is moved the coil spring is contracted to decrease the spacing between the coils, thereby restricting fluid communication between the inlet and the return. Consequently, increased fluid pressure within the other chamber urges the output member to move thereby actuating braking. In addition, a push member carried by the inner wall provides for transmission of movement from the input member to the output member directly.
