Abstract
A hydraulic brake booster includes a housing substantially defining a pressure chamber and movably supporting a control valve and a piston. An input assembly extends into the pressure chamber and cooperates with the control valve to communicate fluid pressure to the pressure chamber. The input assembly is pivotal relative to the piston to a first position wherein fluid pressure communicated to the pressure chamber acts against the piston to move the same while the input assembly remains substantially stationary in the first position. In particular, the input assembly includes a lever with a slot for receiving a portion of the piston. When the lever is pivoted to the first position, the piston portion moves within the slot from one end of the slot to the other end. A pair of springs extend between the housing and the piston and lever, respectively, to bias the piston and lever to a rest position abutting the housing.
