Abstract: A control system for a fluid motor includes a motor direction control valve having a spool and means for selectively shifting the spool in response to fluid pressure signals from a manually operated pilot valve. The directional valve has make-up valve means which automatically opens a bypass passage between the motor ports and fluid return passage when necessary to prevent cavitation of the motor due to an overrunning condition from external load force. The spool of the pilot valve has four positions including one for each direction of motor motion, another for blocking any motor motion and a float position for deliberately interconnecting both motor ports and the fluid return passage so that the motor may move in either direction as determined by external load forces. Unlike the manually actuated pilot valve, the spool of the larger and more costly directional valve need have only three positions as the float function is achieved by relieving the fluid pressure which normally biases one of the make-up valves towards the closed position. Thus a substantial reduction of size and cost of the direction control valve is realized.

Abstract: A hydraulic apparatus including a pair of body members, each having a flat surface, a hydraulic circuit member having two flat parallel surfaces and at least one slot extending in the circuit member between the two parallel flat surfaces, clamping means to hold the body members together with the circuit member clamped between the flat body surfaces, at least one hydraulic component formed on or secured to at least one body member, and ports including at least one port from the component or components. Each port opens into the flat surface of the body member in which it is formed. The arrangement is such that associated ports are connected by a slot in the circuit member which forms a flow passage between the flat surfaces of the pair of body members to carry fluid in a direction parallel to the flat surfaces between the ports.

Abstract: An intrinsically safe hydraulic valve including a first stage in the form of pilot valves and a second stage in the form of a poppet valve assembly. The poppet valve assembly includes first and second pairs of piston operated poppets which, when selectively operated, control the drive direction of a fluid motor. The pilot valves are electrically controlled through an electromagnet arrangement wherein the valves are closed when the electromagnet is de-energized and opened when it is energized. When the pilot valves are selectively opened, they apply a pilot pressure to one or the other of the pairs of piston operated poppets to drive the fluid motor.
