摘要： A brake booster apparatus for a vehicle has a constant pressure chamber, a variable pressure chamber, a control valve, a power piston, a plunger member and a solenoid coil. The plunger member is actuated under the energized condition of the solenoid coil. The power piston is actuated in response to the depression of a brake pedal and/or plunger movement. The output force of the brake booster is amplified by the pressure difference between the variable and constant pressure chambers. A clearance is provided between the input member and the plunger member to permit relative movement of the input member and the plunger member. The relative movement generates a continuous variable output force of the brake booster.

摘要： A master cylinder includes a cylinder body, primary cups supported on the inner periphery of the cylinder body, and a primary piston and a secondary piston inserted in the cylinder body so as to be in sliding contact with the respective primary cups. The cylinder body is integrally formed with annular walls behind the respective primary cups. The annular walls have a greater inner diameter than the inner diameter of the cylinder body to define annular passages between the annular walls and the respective pistons. Connecting passages having a greater radial dimension than the annular passage are defined between the inner periphery of the cylinder body and the respective pistons behind the respective annular walls so as to communicate with a reservoir. While the master cylinder is not actuated, piston ports formed in the respective pistons communicate with the reservoir through the respective annular passages and connecting passages. Brake fluid can thus be sucked smoothly into the respective pressure chambers both during a return stroke of the pistons and during automatic brake control such as vehicle stability control.
