A system includes a variable displacement pump (VDP (102)) in fluid communication with an inlet line (104) and with an outlet line (106). The VDP (102) includes a variable displacement mechanism (108) configured to vary pressure to the outlet line (106). T...

A system includes a variable displacement pump (VDP) (102) with a pump inlet (104) and a pump outlet (106). The VDP is configured to receive a flow at the pump inlet at a first pressure and to outlet a flow from the pump outlet at a second pressure elevate...

A variable displacement piston pump, having: a housing (170), a pivot assembly (190) to pivot between minimal and maximum pivot angles; a pump cover (350) defining an actuator bore with an actuator piston (370), an actuator arm (380) extending from the act...
