Abstract
A fluid horsepower control system is adapted to operate a fluid load by output of a variable delivery pump having a control cylinder governed by a pressure compensated variable orifice connected in multiple with a load sense control valve for causing fluid flow to be inversely proportional to pump discharge pressure and maintaining constant drop across the orifice, without requiring mechanical feedback from the variable delivery pump to the load sense control valve.
