A rotary air motor driven hydraulic pump has separate pressure and return actuators and first and second stage eccentric driven pistons 180 degrees out of phase and driven by the motor through a gear reduction unit. The pressure and return actuators are on/off/proportional valves and the pump has two pressure relief valves with one adjustable from outside of the pump for a user to set a pressure limit of the pump. Above a certain output pressure limit, a bypass valve shunts flow in excess of that needed to precharge the second stage compression chamber from the first stage piston to an elastic reservoir from which the hydraulic fluid pumped by the pump is drawn. To make the pump stall at a certain output pressure, a pressure limiting valve can be used that cuts off the air supply to the pump at the desired output pressure.

A high pressure metering valve has a valve element with a closing portion, a metering portion and a rapid return portion. The closing portion seats against a corner seat at the end of a valve bore in which the metering portion has a close sliding fit. When the element is unseated, a flow rate can be metered depending on the overlapping length of the metering portion in the valve bore. At the opposite end of the metering portion, the rapid return portion is undercut to be of smaller area than the metering portion to provide a full open state for rapid fluid return.
A hand operated hydraulic pump has a cam that is pivoted by a compensation cylinder that rotates the cam so as to move the pivot of an operating handle closer to the pump plunger as the output pressure of the pump increases.

A hoist for positioning a load (40) includes a plurality of lift cylinders (15), a plurality of position sensors, a plurality of electronically controlled valves, a user input device (22), and a hoist controller (20). Each of the hydraulic hoist cylinders is coupled at one end to the hoist and at an opposite end to the load at a lifting point (45). Each of the position sensors is associated with one of the hoist cylinders and operable to provide position data for the associated hoist cylinder. The electronically controlled valves are hydraulically coupled to the hoist cylinders for extending and retracting the associated hoist cylinders. The user input device is operable by a user to specify load data. The hoist controller is operable to receive the load data from the input device and the position data from the position sensors and in response thereto to control the electronically controlled valves so as to position the load according to the load data.
