摘要： Impact tools are described which are capable of developing percussive forces for rock drilling and other repetitive high force applications. A hydroacoustic oscillator contained in such tools includes a hammer and a valve mechanism which is actuated by the hammer for controlling the flow of pressurized fluid so as to establish pressure variations which sustain the oscillation of the hammer. A number of alternative valve mechanisms are disclosed, each including a valve element, the motion of which is controlled by controlling the flow of fluid with respect to the valve element as the hammer and valve element move relative to each other. Such flow control is afforded by chambers defined by the valve element; hydraulic fluid flow with respect to which is controlled so as to determine the deceleration of the valve element and the motion of the element in its actuation by the hammer.

摘要： A plunger pump or plunger motor includes a block accommodating a first cylindrical chamber and a plunger movable in this chamber and a drive shaft connected to this plunger, as well as a second cylindrical chamber and a control valve movable in this second cylindrical chamber. Holes O3 and O4 can alternately be brought into communication with the connection for the delivery pipe by the plunger and with a connecting hole for a pressure line. The control valve can establish a communication between the hole O2 and the connecting hole. The drive shaft is connected to a further plunger which is movable in a third cylindrical chamber in which there is a suction hole or delivery hole. The control valve can alternately establish a communication between the suction hole or delivery hole with a connecting hole for a suction pipe and the connecting hole for the pressure line.

摘要： A hydraulic engine employs dual cylinders and pistons of different diameter connected end-to-end in collinear alignment. Fluid from a pressurized source drives the large piston to transmit power to a crankshaft. An electromagnetic actuator, controlled by a distributor, opens a control valve, admitting fluid to the large cylinder. A hydraulic actuator closes the control valve, shutting off fluid flow. The hydraulic actuator responds to pressure drop when the large piston uncovers an exhaust port. Fluid drains to a tank, and the cycle repeats. The small piston recirculates fluid from the tank to the source.

摘要： Motor apparatus which converts hydraulic energy and change of state heat energy to mechanical energy. The motor includes a main chamber divided by a piston into first and second portions. During a first half cycle or hydraulic power stroke, a valve places the first portion of the chamber in fluid communication with a source of pressurized, saturated liquid and the second portion of the chamber in fluid communication with a drain port. A switch senses the end of the hydraulic power stroke and causes the valve to move to a second position wherein the first and second portions of the chamber are placed in fluid communication with one another to form a common motor chamber and drive the piston in an expansion power stroke. Power is derived from the working fluid during the piston stroke in each direction. The motor finds particular application for energy recovery in an absorption refrigeration system.
