    摘要: This invention pertains to a hydraulic reciprocating device having a housing and a piston in the housing. The piston has a first and second surface, and a means for intermittently communicating the first surface of the piston with a hydraulic pressure source. Also provided is a means for continuously communicating the second surface of the piston with pressurized fluid such as pneumatic fluid. The piston moves in a first direction when the hydraulic pressure source communicates with the first surface of the piston and the piston moves in a second direction when the hydraulic pressure source does not communicate with the first surface of the piston.

    摘要: An impact tool. A piston movable in a cylinder is pushed up by hydraulic pressure, compressing a gas in a chamber over the piston. The compressed gas drives down the piston by its repulsive force to strike a tool such as a chisel. A valve body in a valve chest in a valve box attached to the cylinder is also reciprocated up and down by hydraulic pressure to communicate an oil supply port for hydraulic pressure to act on alternately the piston and the valve body.
