摘要： An antiskid apparatus for an automotive vehicle having a master cylinder connected to wheel cylinders via respective brake lines, and a pressure regulating valve in a power hydraulic pressure line connecting an accumulator with a directional control valve, which is installed in a power hydraulic pressure line connecting the accumulator with a hydraulic pressure control piston. When the brake is applied, the pressure regulating valve is operable, in dependence upon master cylinder hydraulic pressure delivered by each wheel cylinder, to reduce power hydraulic pressure supplied by the accumulator to a hydraulic pressure higher, by a predetermined amount, than the master cylinder hydraulic pressure, and to deliver this reduced hydraulic pressure to each directional control valve. When the brake is not applied, the pressure regulating valve cuts off communication between the accumulator and each directional control valve and brings the hydraulic pressure in a hydraulic pressure line leading to a fluid chamber of the control piston to a value not higher than a set value through the directional control valve. Thus, the fluid chamber is supplied with hydraulic pressure reduced to a predetermined value to suppress a pressure change that occurs in the fluid chamber when the apparatus is operated, thereby reducing shock and noise and making it easier to control the operation of the apparatus.

摘要： An anti-skid apparatus for installation in a vehicle braking system having a master cylinder, a wheel brake cylinder and a primary fluid passage connecting these cylinders includes a changeover valve disposed in the primary fluid passage to selectively communicate the wheel brake cylinder with the master cylinder or with a reservoir, and a fluid pump for pumping a brake fluid from the reservoir and returning it to a portion of the primary fluid passage between the master cylinder and the changeover valve. The anti-skid apparatus further includes a control valve disposed in that portion of the primary fluid passage. The control valve comprises a piston slidably disposed in a housing, and a valve member slidably disposed in the piston and seatable on a valve seat with a cutout formed thereon. The control valve allows a flow of the brake fluid from the master cylinder and/or the fluid pump to the wheel brake cylinder through the changeover valve without restriction in normal braking operation. In the anti-skid operation, the control valve allows a restricted flow of the brake fluid through the cutout to reduce the increasing speed of the hydraulic pressure in the wheel brake cylinder.

Also included is an electric motor, a pump driven by the electric motor, an accumulator adapted to accumulate fluid pressure generated by the pump, a control piston reciprocating under the fluid pressure to open and close the first valve, a second valve adapted to supply the fluid pressure to the control piston upon normal rolling of wheels so as to move the control piston to a non-operative position while excluding the fluid pressure from the control piston when the wheels are likely to lock up, and a third valve having first and second valves and controlling the fluid pressure to be supplied to a hydraulic chamber in response to depression and release of a brake pedal. In this arrangement, a relief valve is provided in a seat member of the first valve so that when the fluid pressure exceeds a predetermined upper limit, it is opened to introduce hydraulic fluid to a drain line through the second valve.

The cylinder bore accommodates the components of two separate valves, namely first, second and third seat members and first and second valve elements brought into and out of contact with seat surfaces of these seat members, as well as a spring interposed between the two valve bodies, a pressure reducing piston and a by-pass piston. First and second passageways arranged in parallel each interconnect the inlet and outlet ports through two serially arranged valve cavities in the cylinder bore and are opened and closed in a prescribed manner by the two valves in cooperation with the spring and pistons. The third seat member has seal rings fitted in first and second annular grooves formed in its outer periphery for providing a seal between the outer periphery of the third seat member and wall surfaces of axially extending bores in the first and second seat members. The diameter of first and second end portions outwardly of the first and second annular grooves, respectively, of the third seat member is such that these end portions will not contact the wall surfaces of the axially extending bores of the first and second seat members, respectively.
