Claims

[Scope of utility model registration request]

The piston 3 connected to the output rod 4 is formed so that its pressure receiving area is smaller on the backward cylinder chamber 9A side than on the forward cylinder chamber 9B side, and a pressure fluid supply path a is provided in the backward cylinder chamber 9A. Connect and connect the forward cylinder chamber 9B.
A sliding spool 5 is connected to the piston 3 so that the sliding spool 5 can be switched between a forward movement state in which it communicates with the pressure fluid supply path a and a backward movement state in which it communicates with the drain flow path a, and is operated to switch as the piston 3 reciprocates. An interlocked vibration generating device includes a fluid supply/discharge port P3 that opens into the double-acting cylinder chamber 9A, and
The bottoms of the cylinder chambers 9A, 9B are arranged so that the fluid supply/discharge port P4 that opens into the forward cylinder chamber 9B is almost completely closed by the piston 3 before the piston 3 reaches the mechanical stroke end. A vibration generator placed away from the wall.
