ABSTRACT:
A braking system for a vehicle is disclosed which includes a master cylinder, a wheel cylinder for braking a wheel or wheels with the brake fluid pressure supplied from the master cylinder and a pulsating-pressure absorbing apparatus arranged between the master cylinder and the wheel cylinder. The pulsating-pressure absorbing apparatus includes a throttle for limiting the brake fluid flowing from the side of the wheel cylinder towards the master cylinder and a plunger arranged between the inlet and outlet of the main body. The plunger is movable in response to the brake fluid pressure difference between both sdes of the plunger. When the plunger is located at the first side of the outlet, the throttle becomes operative and when the plunger is located at the second side of the inlet, the throttle becomes inoperative.
