Abstract
A load sensed variable output gear pump having adjustable high pressure compensation, tuneable response, low unloading pressure and variable pressure drop adjustability. It comprises a unitary housing enclosing a pump which pumps through a main inlet-outlet passage which by-passes through a fixed control and a variable control to an outlet passage leading to a reservoir. An overload control may also be used connected to an inlet load sensing passage which tends to close said fixed and variable controls.
