    Abstract: An improved method and apparatus for adjusting the flow of a diaphragm pump. The thickness of the diaphragm itself is capable of being adjusted. Full stroke output is thereby reduced in inverse proportion to the increased volume occupied by the diaphragm. Adjusting the thickness of the diaphragm while the pump is operating provides a means of varying pump output without stopping the pump for adjustments or modifications.

    Abstract: An apparatus for controlling an electrohydraulic system of a work machine having an engine that drives a variable displacement pump is disclosed. The apparatus includes a pump displacement setting device that produces a pump command signal, a pressure sensor that detects the fluid pressure associated with the variable displacement pump and produces a pressure signal, and an engine speed sensor that detects the speed of the engine and produce an engine speed signal. A microprocessor computes the torque demand on the engine in response to the desired pump displacement, determines a torque limit associated with the engine in response to the engine speed, and responsively modifies the pump command signal to limit the engine torque.

    Abstract: A hydraulic oil well pump drive system for driving an oil well sucker rod includes a master piston positioned within a master cylinder for axial displacement between first and second ends of the master cylinder. The master piston has a piston drive rod which extends through one end of the master cylinder. The drive rod is connected to a crank pin of an eccentric crank. A center seal assembly divides the master cylinder into a working chamber and a pressure chamber in opposite ends of the master cylinder. Each respective chamber defines a fluid volume which varies with the displacement of the master piston. The master piston displacement creates a bi-directional flow of working fluid from the working chamber. A wellhead hydraulic assembly is operably connected to the oil well sucker rod and is in fluid communication with the master cylinder working chamber to receive the working fluid flow. The wellhead hydraulic assembly is responsive to the working fluid flow to reciprocate an oil well sucker rod at a rate which relates to the rate of master piston displacement. A gas accumulator is in fluid communication with the master cylinder pressure chamber to bias the master piston toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly.

    Abstract: Rotational force from a driving device 11 is transmitted to an eccentric cam 32 through a rotating rod 31, and the eccentric cam 32 causes a piston 22 and a piston rod 25 to move up and down in a reciprocating manner by its rotation. Atmospheric air is inspired into a first chamber R1 in a cylinder 21 upon the descent of the piston 22. Upon the rise of the piston 22, the air in the first chamber R1 is compressed, and the compressed high-pressure air is discharged to an accumulator 12 through a discharge valve 25. The accumulator communicates with a second chamber R2 in the cylinder 21. When the air pressure in the accumulator 12 increases, this high-pressure air pushes the piston 22 to cancel the contact between the piston rod 26 and the eccentric cam 32, whereby the power transmission from a power transmission device 30 to a pressure conversion mechanism 20 is cut off.
