Claims

[Scope of utility model registration request]

The inside of the housing is divided into two chambers by a piston with a diaphragm, and by introducing negative pressure and atmospheric pressure into both chambers, the piston is moved by the differential pressure between the two chambers, and this movement is transferred to the brake mask cylinder through an output rod. A control valve and an air valve are arranged in series on the operating axis of the piston to transmit pressure to the piston, and the control valve is arranged on the communication circuit between the two chambers, and the air valve is connected to the single-force chamber. The piston is provided with a seat disposed on the atmosphere release circuit of the piston and cooperating with the control valve, and both valves are interlocked with a bushing rod that is linked to the brake pedal and are connected to a differential along the booster operating axis between the bushing rod and the piston. In response, one valve is opened and the other valve is closed, and when the booster is at rest, the piston is engaged with the recess of the piston and the recess of the air valve to define the retracted position of the air valve. In a brake booster in which the piston is stopped when the outer end of the key comes into contact with the inner wall of the housing, the key is formed into a substantially W-shape, and both ends of the retainer are engaged with the ends of both arms. A brake characterized in that the retainer is formed of a metal linear member, the inner center portion of which is brought into elastic contact with the outer surface of the piston, and the W-shaped key is held by the contact and engagement of both ends of the retainer. booster.
