Abstract
PURPOSE: To obtain a high response characteristic, by displaying a big damping effect when in a changeover of spool to the direction of operating the actuator, and rapidly making a reset when in its resetting operation in the method of free discharge of oil.
CONSTITUTION: With a hydraulic changeover valve 2 switched the position IIW I, if led the pressurized oil of a hydraulic pump 1 to an operating oil pressure pipe line 8, its pressurized oil pushes to open a poppet valve 7 and is fed to a hydraulic motor 3. A pressurized oil, passing an oil passage 11 to act on an oil chamber 10, goes into a damping room 21 through a throttling oil hole 20 of a spring receiver 19, and slides a spool 5 rightward while displaying a damping effect. If cut off a feed of pressurized oil to the operating oil pressure pipe line 8, though with the spool 5 intended to be returned by the reaction of a spring 6', a pressurized oil in a left end of the spool 5 presses the spring receiver 19, to construct a clearance between a level difference part 22 and the spring receiver 19, consequently, a rapid return can be made without being applied a damping action of the throttling oil hole 20.
