バルブ。 A passage communicating with both working hydraulic pressure chambers of a reciprocating hydraulic cylinder device for moving a steering linkage mechanism of a vehicle; a hydraulic pressure for sending hydraulic fluid in a reservoir to the reciprocating hydraulic cylinder device; The bushing valve is slidably housed in a bushing valve having a passage communicating with the pump and a passage communicating with the reservoir, and is slid back and forth by the rotation of the input shaft, thereby controlling the hydraulic pressure of one side of the reciprocating hydraulic cylinder device. The chamber and the other hydraulic pressure chamber are connected to the hydraulic pump and the reservoir, respectively, in response to rotation of the input shaft in one direction, and communicated to the reservoir and the hydraulic pump, respectively, in response to rotation of the input shaft in the other direction. In a control valve for a hydraulic power steering device having a plurality of lands on its outer periphery having control edges for switching each passage, the ends of the control edges of the control valve have a tapered shape with both ends having a small diameter. In addition, a damper is provided on the outer periphery between each land portion of the control valve to divide a chamber formed between each land portion into two chambers that communicate with each other via a throttle. control valve for the extraction device.
