  • Patent number: 6748847
    Abstract: A brake booster 1 includes a valve mechanism 6, and a solenoid 8 which operates the valve mechanism 6. When the solenoid 8 is energized, a solenoid plunger 26 and a valve seat member 11 move rearward relative to a valve body 3, whereby the valve mechanism 6 is operated to actuate the brake booster 1 without depressing a brake pedal. A core member 27 which forms a magnetic path for the solenoid 8 is disposed rearward of the solenoid plunger 26 so as to be movable axially of the valve body and so as to move in linked relationship with a valve plunger 13. The invention allows the size of the solenoid 8 to be reduced.

  • Patent number: 6634275
    Abstract: An automatic brake booster 1 includes a solenoid 8 which causes a back- and forth movement of a solenoid plunger 31 to switch a valve mechanism 6. A second vacuum valve seat member 11 including a second vacuum valve seat 12 which is juxtaposed with a first vacuum valve seat 10 on a valve body 3 and a pressure responsive area 34 subject to a pressure of a variable pressure chamber and a pressure of a constant pressure chamber is slidably mounted on the valve body. The effect of the pressure differential acting upon the pressure responsive area is balanced with the force resulting from the excitation of the solenoid plunger 31 to deliver a brake output which corresponds to the force. The invention enables a high accuracy control of a brake output during an automatic brake operation.

  • Patent number: 6467267
    Abstract: In a brake fluid pressure boosting device 1 of the present invention, by operation, an input shaft 4 is moves forward to rotate a lever 27 to actuate a control valve 8 so that the control valve 8 produce working fluid pressure corresponding to the input. The working fluid pressure is introduced into the power chamber 6. By this working fluid pressure, the primary piston 37 is actuated to develop master cylinder pressure. On the other hand, the fluid pressure of the power chamber 6 is introduced into the first annular groove 25 of the valve spool 10. By the difference between pressure receiving areas of the first annular groove 25, the valve spool 10 is subjected to rightward force. The position of the pivot of the lever 27 is fixed and the valve spool 10 is controlled in such a manner that the force applied to the valve spool 10 and the spring force of the spool return spring 32 balances with the input, thereby exhibiting the function as a stroke simulator.

  • Patent number: 6263305
    Abstract: A software development supporting system of the ROM emulation type is provided, which facilitates the electrical connection to a target system equipped with no ROM socket. This system is comprised of a ROM controller electrically connectable to a PCI bus of a target system, a ROM emulator for emulating an operation of a target ROM mounted on the target system, and a host computer electrical connected to the ROM emulator. The ROM controller receives a control signal for controlling the target ROM, in which the control signal is transmitted through the PCI bus of the target system. The ROM controller transfers the received control signal to the ROM emulator, thereby controlling the ROM emulator. Preferably, the ROM controller is designed to output an access assertion signal to the PCI bus before a ROM controller of the target system outputs an access assertion signal of the target ROM. Thus, the ROM emulator serves to emulate the target ROM using the control signal.

  • Patent number: 6161380
    Abstract: A booster 3 has a structure that a return valve 14 is formed into a two-step throttle incorporating a first throttle valve 36 and a second throttle valve 37 formed continuously from the first throttle valve 36. When a valve spool 28 has been moved forwards when the operation is performed, a gap of the first throttle valve 36 is reduced. Also a gap of the second throttle valve 37 is reduced. Therefore, hydraulic fluid discharged from a pump is passed through an inlet passage 12, and then introduced into the second annular groove 13. Then, the hydraulic fluid is throttled by the first throttle valve 36, and then throttled by the second throttle valve 37. That is, the hydraulic fluid is throttled in the two-step throttling manner. As a result of the two-step throttling structure, the overall velocity of the flow of the hydraulic fluid can smoothly be changed without rapid change. Therefore, fluid flow noise caused from the change in the velocity of the flow can be prevented.
