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 bypasses through a combined control having a single load sense line. The single control including a chamber connected to the load line by means of a popper with a 2:1 area ratio and a spool having a 1:1 area ratio. An overload control may also be used connected to an inlet load sensing passage which tends to close said fixed and variable controls.
