Claims

[Scope of utility model registration request]

Connecting the opposite-head side chamber of one of the two hydraulic cylinders to a switching valve that switches the flow of pressure fluid from the hydraulic pump, and connecting the head-side chamber of the other i-pressure cylinder, A head-side chamber of one of the two hydraulic cylinders and a non-head-side chamber of the other hydraulic cylinder are communicated with each other, and the pressure-receiving portions of the communicated head-side chamber and the non-head-side chamber are disconnected. An operating speed tuning device for a hydraulic cylinder, characterized in that the areas are approximately equal.
