Abstract

PURPOSE: To increase a force to cut off or drill an object, by using a pressurizing piston to impulsively pressurize a liquid in a liquid chamber to instantaneously eject the liquid under very high pressure out of a nozzle.
CONSTITUTION: When a drive piston 19 is rapidly moved forth in its reciprocation, a step portion 33 extending from a small-diameter portion (c) to a larger-diameter portion (d2) goes onto a sliding portion 32 to sharply pressurize a front chamber 23 to rapidly push a pressurizing piston 16 forward through oil in the front chamber 23. As a result, a liquid in a liquid chamber 5 is sharply pressurized by the piston 16. At that time, a check valve 17 is closed to prevent the liquid from escaping to a liquid outlet port 16. The liquid whose pressure is heightened by the pressurizing piston 16 is all ejected out of a nozzle 2 to work an object by a strong cutting-off or drilling force.
