Abstract
PURPOSE: To control flow rate of liquid supplied to an actuator without generating energy loss by relatively rotating and displacing a sleeve and a spool in an axial direction.
CONSTITUTION: In a condition such as indicated in the figure, that is, a spool 9 and a sleeve 10 of a flow control mechanism 7 completely shut off a branch passage and a discharge passage 8 of a hydraulic pressure supplying passage 2, delivery oil of a pump 1 is supplied to an actuator 3 as it is. When a load is applied to the actuator 3 to raise hydraulic pressure in a feeding passage 2, the sleeve 10 is moved rightward resisting a spring 11 by the hydraulic pressure conducted to a step part 20 and ports 13, 15 are partially overlapped. The ports 13, 15 are intermittently opened or closed in accordance with the rotation of the spool 9 as there are multiple ports 13, 15 made at the same angle and the same distance around the spool 9 and the sleeve 10, so that the liquid in the feeding passage 2 is intermittently discharged to a tank 5 side.
