Abstract
A hydraulic pressure control valve is equipped to a cavity to control a communication state between a supply port and an outlet port to supply hydraulic fluid from the supply port through the outlet port to a controlled object. A tubular sleeve has a first port and a second port communicating with the supply port and the outlet port, respectively. A spool includes a land supported by the sleeve slidably in an axial direction to form a hydraulic chamber with an inner circumferential periphery of the sleeve. The spool is displaced in the axial direction to cause the land to control a communication state between the first port and the second port through the hydraulic chamber. A supply-side hydraulic passage is connected with the hydraulic chamber through multiple outflow holes to conduct hydraulic fluid from the hydraulic chamber through the second port to the outlet port.
