摘要： In a hydraulic apparatus providing a base with a discharge passage coupler to a circumferential portion of an annular discharge passage and to a damper chamber, a hydraulic device is connected via an orifice to the discharge passage without arranging the annular discharge passage between the damper chamber and the orifices, so that the damper chamber and the orifices cooperate together to exert an effective attenuating action thereon so as to suppress the transfer of pressure pulsation thereto effectively. Further, in an anti-lock brake control apparatus providing a pipe member which integrally includes an orifice interposed between a damper and a normally open electromagnetic valve, a sheet pipe corrected to an inner end of a connecting hole coaxially with the orifice, and a coupling pipe portion coaxially formed between the orifice and the sheet pipe, the sheet pipe is fitted into a large-diameter portion of the base and the orifice is fitted into a small-diameter portion of the base, thus the number of component parts is reduced and the normally open electromagnetic valves are prevented from malfunctioning due to the clogging of the orifices by dust.

摘要： A hydraulic braking pressure control system which includes a sleeve slidably received in a housing with opposite ends facing an output chamber connected to a brake device, and a pilot chamber connected to a control hydraulic pressure source. A control piston is slidably received in the sleeve, with one end of the control piston facing the output chamber and the other end facing a control chamber connected to the control hydraulic pressure source through a lock valve which is adapted to be closed in response to the movement of the sleeve, in a direction to increase the volume of the output chamber. A cut-off valve located between an input chamber leading to a master cylinder and the output chamber includes a valve member having a maximum amount of movement in a seating direction which is regulated to a position of the valve member spaced apart from a valve seat when a valve seat member follows movement of the sleeve in a direction to reduce the volume of the pilot chamber to the maximum amount. This ensures that the opening of the cut-off valve and tight closing of the control chamber upon an abnormal reduction of the control hydraulic pressure from the control hydraulic pressure reduction source can be achieved with a simplified system.

摘要： An electromagnetic valve device includes a valve operating unit formed by disposing valve components in a valve housing having a guide cylinder and mounted to a base member, and a tip end of the guide cylinder and a housing body are magnetically connected to each other by a magnetic path defining frame surrounding a coil wound around a bobbin. The bobbin is buried in a mold section made of synthetic resin to form a coil unit. The coil unit is mounted to the base member. One end of the magnetic path defining frame is formed with a fitting bore through which the tip end of the guide cylinder is fitted, and the other end of the magnetic path defining frame is capable of abutting against the housing body. The magnetic path defining frame is mounted to a coil-correspondence portion of the mold section. The guide cylinder is loosely passed through a center bore of the bobbin. With this arrangement, a magnetic path can reliably be formed by the magnetic path defining frame, and the coil, bobbin and magnetic path defining frame can easily be mounted to each of the valve operating units.

摘要： An electromagnetic valve is fitted with relief means and is made to have a compact diameter without increasing its axial length is provided. The electromagnetic valve is provided with a push bar capable of pushing the valve body toward the valve seat and a relief spring for urging the push bar toward the valve body are contained in a guide hole formed in the central portion of the moving core, wherein a stopper is provided to the moving core, the stopper being used for holding the valve body open by defining a limit to which the push bar is moved forward with respect to the valve body when the moving core is moved backward and for allowing the valve body to be closed by the relief spring when the moving core is moved forward. Thus, the valve body and the push bar are axially arranged separately from each other.

摘要： In a hydraulic braking pressure control system for a rear wheel brake wherein a control piston normally works to provide a hydraulic braking pressure control by cooperation with a cut-off valve interposed between an input chamber leading to a master cylinder and an output chamber leading to a wheel cylinder of the brake, the cut-off valve has a valve seat piston whose pressure-receiving area facing the output chamber is larger than the pressure-receiving area facing the output chamber. This ensures that opening and closing of the cut-off valve can be repeated in accordance with the output pressure from the master cylinder, so that the output pressure from the master cylinder can be reduced and applied to the brake wheel cylinder. When the control hydraulic pressure is lost, the control piston and sleeve can be moved in a direction to increase the volume of the output chamber thereby to close the lock valve and tightly close a control chamber between the control piston and sleeve, while restraining by a stopper the movement of the cut-off valve following in a closing direction of the control piston and sleeve. This makes it possible to insure a hydraulic braking pressure applied to the brake wheel cylinder.
