摘要: The present invention presents an economical fluid pressure control device particularly applicable to controlling the fluid pressure in the wheels of an automobile provided with an antiskid capability so that the unpleasant pedal kickbacks are prevented under various operating conditions of the wheels. This is achieved by providing at least two wheel cylinders for one pressure generation source, a reservoir and a pump. A flow valve provided on each of the wheel cylinders is provided with a simple flow switching device which control the position of a spool, disposed inside the flow valve, which assumes a stationary position for non-antiskid operation mode and a operation position for antiskid operation mode. When one of the wheels is in the antiskid operation mode, and the other wheel is in non-antiskid operation mode, the brake fluid discharged from the pump is not allowed to enter the flow valve disposed in the non-antiskid operation mode. Therefore, the fluid pressure pulsations generated in the fluid circuit in the antiskid operation mode are not transmitted back to the pressure generation source through the flow valve in the non-antiskid operation mode. Therefore, there in no transmission of unpleasant pedal kickbacks at the pressure generation source.

摘要: A valve body 2 is connected to a power piston, which divides a housing into a constant pressure chamber (negative pressure) and a variable pressure chamber. In the valve body 2, there is provided a brake assisting mechanism 10 between a reaction disk 3 and a plunger 9. A poppet seal 12 is opened by movement of the plunger 9, to thereby introduce atmospheric air into the variable pressure chamber and generate a thrust force in the power piston. During rapid braking, a plunger rod 23 advances relative to a sleeve 21, and balls 30 shift outward and the plunger rod 23 directly abuts against a reaction rod 22, resulting in contraction of the brake assisting mechanism 10. Therefore, the amount of movement of the plunger 9 can be increased without being affected by a reaction force from the reaction disk 3, thus enabling rapid development of servo power.

摘要: The present invention provides a booster in which magnitude of output can be adjusted also by an operation of a solenoid mechanism. An armature (13) is shifted to the right (in FIG. 1) in opposition to a returning spring by applying electricity to a solenoid (39), with the result that a space (80) on one end of the armature is communicated with a constant pressure chamber (5) through a passage (T3). When an electromagnetic force acting on the armature (13) exceeds a predetermined value, a distal end of a valve member (28) is shifted to the right (in FIG. 1) via a cylindrical member (31) to open an atmospheric valve (34), thereby introducing the atmosphere into a variable pressure chamber (6). The pressure in the variable pressure chamber is applied to the other end of the armature and the difference in the pressure tends to move the armature toward its home position.

摘要: A brake fluid pressure control system includes an external source of fluid pressure, a wheel cylinder, and a fluid pressure control valve disposed between the external source of fluid pressure and the wheel cylinder. A controller is operable to control the fluid pressure control valve whereby fluid pressure under control is fed from the external source of fluid pressure to the wheel cylinder. When a change in pressure within the wheel cylinder occurs, a fail safe valve is operable to disconnect the wheel cylinder from the fluid pressure control valve and instead, connect the wheel cylinder to a master cylinder. Inspection of the fail safe valve is carried out by disconnecting the wheel cylinder from the control valve when no brake is applied, feeding fluid pressure from the external source of fluid pressure to the wheel cylinder, and detecting a change in pressure within the wheel cylinder. An alert device is provided to give a warning in the event of a system failure.
