摘要： PURPOSE:To improve the reliabilty of a hydraulic brake device which electrically supplies the hydraulic pressure of a hydraulic pressure source to a wheel cylinder. CONSTITUTION:The control force of a control piston 140 and the reactive force of a reactive force piston 76 are allowed to act to the spool 66 of a hydraulic control valve 50, and the hydraulic pressure of an accumulator 82 is controlled to the level boosted in the sectional surface area ratio between the control piston 140 and the reactive force piston 76 at the level corresponding to the stepping force of a brake pedal and supplied to a wheel cylinder 22. The force of a force motor 110 is added to the control piston 140 and the spool 66, and antilock control is carried out by varying the control pressure, and the control pressure is generated, and the acceleration slip control is carried out. The liquid leak from the control pressure chamber 142 is prevented by allowing the control pressure to act to the control piston 140 from a control pressure introducing port 160, and the master cylinder hydraulic pressure is supplied into the wheel cylinder 22 from the control pressure infroducing port 160, when the accumulator fails.

摘要： PURPOSE:To provide improved reliability and size reduction of a hydraulic control valve in a hydraulic brake device which controls the hydraulic pressure of a hydraulic pressure source electrically for feeding it to a wheel cylinder. CONSTITUTION:Hydraulic control valves 50-56 are mounted between a master cylinder 12 and wheel cylinders 22, 24, 34, 36, the hydraulic pressure of an accumulator 82 is controlled according to master cylinder hydraulic pressure, and the hydraulic pressure is electrically-controlled by a force motor. When master cylinder hydraulic pressure exceeds a prescribed value, cut valves 190, 250 are closed, the hydraulic pressure control force of a control piston which receives the master cylinder hydraulic pressure is restricted, so it is possible to make the diameter of the control piston without increasing the size of the force motor, and attain excellent output hysteresis characteristics. If hydraulic pressure is not fed to the front wheel cylinders 22, 24, the cut valve 250 is not closed, and large rear wheel braking force is attained. It is thus possible to avoid reduction of braking force of the whole vehicle with high efficiency.

摘要： PURPOSE:To provide a spool type electromagnetic hydraulic pressure control device which can develop control pressure without delay, and seldom develops improper pressure before starting fluid pressure control. CONSTITUTION:It is detected by a footing detection switch 3O that a brake pedal 20 has been footed, a dither current command signal is outputted from a dither current command circuit 124, so that dither current is supplied to an exciting coil. It is detected by a footing force sensor 128 that the footing force of a brake pedal 20 has come up to a specified value, the supply of dither current is suspended, and concurrently the output of an exciting current command signal is started, which is required to develop control pressure enabling car body deceleration in response to the footing force to be obtained by a basic current command circuit 122. The supply of dither current starts supplying exciting current in response to the footing force of the brake pedal 20, and concurrently makes a spool go ahead without delay, so that control pressure is thereby developed immediately. Since it is good enough that the average value of dither current is even small, improper pressure developed before fluid control starts becomes small.

摘要： PROBLEM TO BE SOLVED: To provide a variable valve gear for an internal combustion engine, which is constructed to change over the valve opening characteristics of valves provided in at least two cylinders in a lump while well securing a response time required for changing over the operating conditions of the valves from second operating conditions into first operating conditions.SOLUTION: The variable valve gear includes a change-over mechanism 32 for changing the operating conditions of rocker arms 18, 20 to change over the valve opening characteristics of the valves 26. The change-over mechanism 32 includes a restricting mechanism for restricting the displacement of a second link shaft 50b during a period for lifting a main cam 14 for a #2 cylinder in which the valve 26 is lifted earlier than the valve in a #1 cylinder when an electromagnetic solenoid 56 is controlled to return the operating conditions of the valves 26 from valve closing stopping conditions into valve operating conditions. Specifically, the restricting mechanism is achieved in the #2 cylinder by integrally joining a first change-over pin 49b to be inserted into a first pin hole 34a of the first rocker arm 18, to a third link arm 49.
