Abstract: An air-operated diaphragm pump and a governor for controlling its speed of operation. An auxiliary pump is driven by the diaphragm pump and pumps a separate fluid through an adjustable orifice. For a given setting of the orifice the pressure of separate fluid varies with the rate of operation of the auxiliary pump. The pressure of separate fluid is transmitted to a control valve which admits more or less air to the diaphragm pump actuator valve in response to changes in the pressure. The actuating valve directs air to the diaphragm pump to cause it to reciprocate. The actuating valve is snapped from one position to another by the mechanism that actuates the auxiliary pump.

Abstract: 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.

Abstract: The improved hydraulically actuated percussion drill described hereinafter is designed to reciprocate a striker piston contained therein regardless of whether or not the striker piston engages the drill steel whereby vibration can be imparted to the drill. The drill includes an overtravel portion that cooperates with the striker piston to prevent metal-to-metal contact of the striker piston with the housing during operation. Means are provided to prevent the loss of fluid from the overtravel chamber whereby the striker piston will be returned to the upper end of its stroke and will not become stalled in the overtravel chamber.

Abstract: A hydraulically driven hammer is disclosed, along with valve actuation arrangements which operate to switch hydraulic forces on the hammer ram after preselected intervals following application of pressurized pilot fluid flows. These flows pass into a fluid accumulation chamber unitl a predetermined volume is accumulated after which continued pilot fluid flow produces valve actuation.

Abstract: In a percussion tool a means is provided for delaying the manifestation, on a valve means sensitive to such change in pressure, of a change in pressure of the fluid applied to the hammer piston at one end thereof and which drives such hammer piston in its working stroke, the valve means being that means which serves to control the inlet and exhaust parts of the fluid circuit which applies pressure to the other end of the piston.

Abstract: A high energy linear actuator includes an enclosed cylinder with a sleeve slideable within the cylinder to define a compression chamber and a liquid chamber on opposite sides of the sleeve. A piston ram extends slideably through the liquid end of the cylinder and the other internal end of the ram is slideable within the central bore in the sleeve to expose the inner end of the ram to the compression chamber. The actuator includes a special sealing arrangement and porting arrangements, which may be controlled by a variety of valve systems. The actuator is operated by pumping a pressurized liquid into the liquid chamber to urge the sleeve and piston in unison toward the opposite end of the cylinder and compressing the gas in the compression chamber. The seal between the sleeve and piston then is broken to relieve the advancing force of the pressurized liquid on the piston. The force of the compressed gas then acts immediately on the exposed inner end of the piston to drive the piston at high velocity and with substantial force.

Abstract: A hydraulically-operated road breaker comprises a casing with a tool mounting and housing an oscillatory piston/striker and cylinder arrangement. A sequence valve mounted in the casing controls pressurization and exhausting of the piston to produce power and return strokes of the piston. Pilot port means positioned in the cylinder of the device are uncovered, at the end of each return stroke of the piston, to allow a valve-actuating flow of hydraulic fluid through the port means to change over the sequence valve and thereby cause stroke reversal of the piston. Manually-operable stroke selection means provide for adjustment of the position of the piston in the cylinder at which the valve-actuating flow occurs, whereby to vary the piston stroke.
