Abstract

A system includes a variable displacement pump (VDP) in fluid communication with an inlet line and with an outlet line. The VDP (102) includes a variable displacement mechanism configured to vary pressure to the outlet line. A relief valve (RV) includes an RV inlet in fluid communication with the outlet line, and an RV outlet in fluid communication with a bypass line that feeds into the inlet line upstream of the VDP (102). An actuator is operatively connected to control the RV (110) to change function of the RV (110) between a first function and a second function. The first function is a high pressure relief valve function. The second function is as a wind milling bypass function. A controller is operatively connected to the actuator to control the RV (110) to change back and forth between the first function and the second function.
