Abstract
The brake booster (12) includes a housing (30) with at least one piston (38) disposed in a bore (32) between a pressure chamber (42) and a work chamber (76). The piston (38) is disposed adjacent a valve housing (79) containing therein a valve assembly (80) and the valve assembly (80) is connected to an input assembly (72) at an end of the valve housing (79). The piston (38) includes a cam surface (78) engaged by a lever (17), the lever (17) abutting an actuator part (81) biased by a resilient spring (83) toward the lever (17). Actuation of the booster (12) effects a greater displacement of the piston (38) than the input assembly (72) and valve housing (79) because of the engagement of the lever with the cam surface (78) of the piston (38).
