Abstract
A cylinder chamber 17 at the front of a direct-acting type actuator section 10 is connected to a cylinder chamber 37 at the front of an oscillating type actuator section 30 through a sequence valve with check valve 40. Further, a cylinder chamber 18 in the rear of the direct-acting type actuator section 10 is connected to a cylinder chamber 38 in the rear of the oscillating type actuator 30 through a stop valve 50. Ports 61 and 62 are provided for connecting passages between the cylinder chamber 37 and the sequence valve with check valve 40 and between the cylinder chamber 18 and the stop valve 50, respectively, for distribution control of a working fluid. According to the setting conditions of the respective valves 40 and 50, the piston rod 11 can perform an ordinary reciprocating motion and a motion that combines rotation and advancement.
