ABSTRACT:
A fluid flow controlling device includes a flow control that is interposed between the valve spool of a directional control valve and the work port channel of the directional control valve, and that is effective to control fluid flow to and from one motor port of a fluid motor in proportion to respective sizing of first and second fluid flow paths by the valve spool. The fluid flow controlling device is preferably used in load responsive hydraulic systems.
