Versatility in Compensated Hydraulic Circuits

A compensated hydraulic system is a system in which the pump automatically compensates or reacts, usually by a change in displacement, to some change in its operating condition or to some external signal. An almost endless variety of operating characteristics to provide many conveniences is possible.

Pressure- and flow-compensated systems are familiar but still have new possibilities. In addition, torque compensation, speed compensation, and various hybrid systems are now feasible. The features of several existing and proposed systems are examined in this paper.
