Abstract

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). The VDP (102) includes a variable stop (110) configured to vary minimum displacement of the variable displacement mechanism (108) based on position of the variable stop (110) relative to a housing of the VDP (102). A pressure sensing valve (PSV (114)) is operatively connected between the inlet line (104) and the outlet line (106) to actuate a stop member (116) to adjust stopping position of the variable stop (110) based on pressure differential between the inlet line (104) and the outlet line (106).
