本发明涉及种油压调节阀，其包括支撑在轴套(6)中以在轴向上可滑动的阀柱(7)、布置为产生用于将阀柱驱动到个轴向端侧的电磁力的螺线管致动器(8)，以及构造为将阀柱偏压到另个轴向端侧的偏压部分。该轴套设置有输入室(11)和输出室(12)，油压输入端口开放到该输入室，油压输出端口开放到该输出室。该阀柱包括台阶部分(7a)，该台阶部分暴露于输出室，以通过使用输出室中的油压而被偏压到个轴向端侧，并且当台阶部分通过使用输出室中的油压而被偏压到所述个轴向端侧时，该阀柱可移动到所述个轴向端侧。 An oil pressure regulation valve includes a spool supported in a sleeve to be slidable in an axial direction, a solenoid actuator disposed to generate an electromagnetic force for driving the spool to one axial end side, and a biasing portion configured to bias the spool to the other axial end side. The sleeve is provided with an input chamber to which an oil pressure input port is open, and an output chamber to which an oil pressure output port is open. The spool includes a land portion that is exposed to the output chamber to be biased to the one axial end side by using oil pressure in the output chamber, and the spool is movable to the one axial end side when the land portion is biased to the one axial end side by using the oil pressure in the output chamber.
