摘要： A fluid pressure controller has a houisng including an input port, a discharge port and an output port, and a spool is axially slidably mounted in the housing. First and second chambers are defined at opposing ends of the spool by the spool and the housing. Ring valve members are mounted on the spool at axial spaced locations to define oppositely oriented variable-size orifices for pressure increase and pressure reduction. They are adapted to separately control communications between the first chamber and the input port and between the first chamber and the discharge port depending upon the axial position of the spool and to close both communications when the spool is in its closed position. Thus the pressure controller can be freely changed between providing pressure increase, pressure reduction and pressure hold.

摘要： A flow control valve includes a sleeve formed with an inlet port and an outlet port and a spool slidably mounted in the sleeve. A fluid passage having an orifice connects a high-pressure end and a low-pressure end of the spool. An annular seal is liquid-tightly fitted in an annular groove formed in the inner periphery of the sleeve and extends into an annular groove formed in the outer periphery of the spool with a gap left therebetween. A biasing elements is provided to bias the spool in a direction opposite to the direction in which the fluid pressure differential between both ends of the spool tends to urge the spool. A seal can be effected by the annular seal and a shoulder portion of the spool defining the annular groove thereof. The seal, however allows fluid communication from the inlet port toward the outlet port through the orifice to be established with the movement of the spool.

摘要： A brake pressure control device for vehicles is arranged in a pipeline connecting a master cylinder (22) and a wheel brake (23) with an electromagnetic directional control valve (24) which is switchable to any one of a plurality of valve positions by electromagnetic force. The electromagnetic directional control valve (24) is switched between a first valve position and a second valve position. Bidirectional flow of fluid is allowed when the electromagnetic directional control valve is in the first valve position. Unidirectional flow of the fluid is allowed but a reverse flow of the fluid is prevented when the electromagnetic directional control valve is in the second valve position.

摘要： An antilock mechanism for use in a hydraulic brake system including a hydraulic pressure source, a wheel brake, and a drain channel, includes a flow control valve and a drain valve provided in the drain channel. The flow control valve has an inlet port connected with the hydraulic pressure source, a first outlet port connected with the wheel brake, and a second outlet port connected with the drain channel. A spool is slidably inserted in the housing. The spool comprises first axial conduit and a second axial conduit separated by a wall having a fixed orifice formed therein, and is biased by a return spring. The drain valve is located adjacent the open end of the housing such that the second outlet port of the flow control valve and a valve member of the drain valve are connected straight.

摘要： A fluid pressure controller having a housing having a first port and a second port, and a spool axially slidably mounted in the housing. First and second chambers are defined between opposing ends of the spool between the spool and the housing. The controller further has an electricity/power converter for applying to the spool an axial driving force corresponding to the magnitude of an electric command, and a spring for holding the spool in its initial position when the value of the electric command to the converter is zero. A variable-size orifice is provided to separately control communications between the first chamber and the first port depending upon the axial position of the spool. The second chamber normally communicates with the second port. A fixed-size orifice and a relief valve are provided parallel to each other in passages connecting the first and second chambers.
