Abstract
Disclosed is a liquid inertia tool in which the kinetic energy of flowing liquid is converted to useful work by decelerating the liquid flow and directing the inertia force in the water against a movable element in the liquid flow-containing structure which in turn moves against a work piece. Flow deceleration is achieved by an orifice-effect valve. The valve is reset for flow resumption or acceleration by automatically or selectively applying hydraulic pressure to a reset mechanism. Use of the inertia tool in pile driving and punch press applications is disclosed.
