Abstract
A hydraulic booster for a brake system or the like, of a vehicle includes a throttle valve which produces hydraulic pressure corresponding to the depression force applied to a brake pedal. Relative axial displacement of an operating rod and a power piston produces relative rotation of a power piston. The throttle valve is formed between the power piston and the booster body, and responds to the relative rotation of the power piston.
