摘要： A variable displacement pump system including a pressure and a load sensing compensator (18,19) for operating a pump adjusting mechanism (11-13) to vary the displacement by applying hydraulic fluid to a hydraulic positioning piston (13) and a spring biased piston (12). The load sensing compensator (19) senses the pressure drop of the working fluid flow across a system valve (15) and applies a modulated pressure to the hydraulic positioning piston (13). The spring biased piston (12) is connected (line 21) to a load sensing line (20).

摘要： An electro-hydraulic servo control system which includes a servo actuator adapted to variably position a load mass, and an actuator control system which includes a sensor coupled to the actuator for providing an indication of measured actuator position and a digital observer responsive to measured actuator position for estimating velocity and acceleration at the actuator. Signals indicative of measured actuator position, estimated velocity and estimated acceleration are fed to a comparator, together with a position command signal, for obtaining a difference or error signal to provide a control input to the actuator. The observer electronics includes digital computation means suitably programmed to estimate position, velocity and acceleration as solutions to three linear equations with three unknowns. Equation constants, which are functions of actuator and driven mass physical characteristics, are entered through operator-adjustable resistors. The actuator position and error input signals are periodically sampled and stored as inputs to the observer electronics. The observer electronics also embodies a self-test feature to facilitate maintenance in the field.

摘要： An electro-hydraulic servo valve system comprising a two-stage spool type servo valve including a first stage (20) comprising an electrical force motor (12) and a second stage (21) including a spool (28) for controlling flow to an actuator (14). The force motor (12) is operable upon receipt of a command electrical signal to cause to move the spool (28). A first feed-back (16) is operable to cause the force motor (12) to stop the movement of the spool (28). A second feedback (19) is also operable to stop the movement of the spool (28) at a predetermined position. The second feedback (19) has a greater gain than said first feedback (16) so that it normally dominates in the system. The second feedback (19) comprises a pair of identical electrical sensors (35, 36) connected in parallel, and operable by movement of the spool (28). A comparator circuit (18) compares the electrical signals from the sensors (35, 36) and is operable when the signals deviate from one another by a predetermined amount to disable the second feedback (19) so that the first feedback (16) will function permitting the electro-hydraulic servo valve system to operate without the second feedback (19).
