Abstract:
A fluid actuated system comprising:a variable delivery pump having a piston and a high pressure conduit, an actuator having a plunger, moveable between a first position at which a maximum fluid output being delivered and a second position at which a minimum fluid output being delivered, a position sensor connected to said pump and being adapted to deliver a signal relative to the position of the actuator between said first and second position; a fluid pressure sensor connected to said high pressure conduit and being adapted to deliver a pressure signal representative of a fluid pressure in said high pressure conduit; and an electronic control module connected to receive said pressure signal and said position signal, and delivering a first directional move signal in response to said pressure signal being below a first predetermined value and said actuator being at a location between said first and second positions, said actuator receiving said first directional move signal and moving said plunger in a first direction toward maximum fluid output.
