摘要： A hydraulic braking system capable of reducing the brake pedal stroke is provided by adding to the basic hydraulic braking system. The adding system is able to selectively execute the reduction of brake pedal stroke and, at the same time, capable of selectively adding anti-lock function and anti-slip function by including the changeover valves or opening and closing valves to the system. An auxiliary hydraulic pressure generator having a power hydraulic pressure source and regulator is interposed in the hydraulic conduit of at least one circuit, and an outlet port of the regulator is communicated to the wheel cylinders for connecting to the hydraulic conduit of the circuit. Brake pedal stroke can be reduced by inclusion of other conduit arrangements for adding the auxiliary hydraulic pressure generator and, at the same time, the changeover valve, anti-lock control changeover valve, and normally closed valve are selectively releasably added or mounted to the system, so that a brake system having short brake pedal stroke and sporty feeling can be obtained by low cost system ensuring desired braking operation. Additionally, anti-slip control for preventing the slipping of driving wheels can be added.

摘要： The invention is directed to a hydraulic booster for use in a hydraulic braking system of an automotive vehicle having a power source for generating a hydraulic power pressure, a reservoir and a master cylinder for generating a hydraulic braking pressure in response to movement of an input rod. The hydraulic booster has a housing defining therein a boost chamber, a power piston received in the boost chamber for transmitting a boost force to the master cylinder, and a pressure control valve which introduces the hydraulic power pressure from the power source and controls it in response to the movement of the input rod. The pressure control valve includes a cylinder defining therein a bore and a spool received in the bore. The spool has an axial hole and at least two radial holes facing each other and communicating with the axial hole. And, a tubular member is disposed in the axial hole of the spool to prevent the interference of the hydraulic power pressures introduced into the axial hole through the radial holes facing each other, whereby an uncomfortable noise caused by the interference is effectively prevented.

摘要： A hydraulic brake apparatus is provided for increasing a braking force with a brake feeling similar to that during a normal brake operation, even if a brake pedal is operated during an automatic brake operation. A valve device having a spool is placed in a power piston and is transferred between first and second positions depending on the operation of the brake pedal. At the first position, a power chamber is at atmospheric pressure level, while at the second position a fluid communication is established between the power chamber and an auxiliary hydraulic pressure source. The spool is driven independent of the operation of the brake pedal. When a hydraulic pressure is applied to the spool, the valve device is switched to the second position, urging the power piston to advance, without transmitting the resultant force to the brake operation member. The driving device, when applied with no hydraulic pressure, retains the valve device at the first position.
