Abstract

PURPOSE: To prevent a hydraulic circuit from being adversely affected by vibration or the like in operation, by providing a three-position changeover valve to set a neutral position to release pressurized oil out of a power cylinder.
CONSTITUTION: The chambers of a power cylinder at the side of a rod 1 and at the opposite side are connected to a three-position changeover valve 4 through check valves 3a, 3b. When the three-position changeover valve 4 is in its neutral position, the chambers of the power clyinder 2 at the side of the rod 1 and at the opposite side are connected to a release passage 10. This results in preventing an adverse effect that the rod 1 would be vibrated by vibration during the operation of an automobile to cause pumping action in the power cylinder to apply undesired hydraulic pressure to a hydraulic circuit.
