A variable displacement pump ( ) having a combination inlet port ( ) and an outlet ( ) formed integrally on the rear body ( ). By integrating the combination inlet port ( ) and outlet ( ) on the rear body ( ), this invention simplifies the manufacture of the pump ( ) as compared with known variable displacement pumps.

Variable displacement pump

A variable displacement pump having an electronically modulated solenoid relief valve for controlling fluid flow into the pump . An engine control module coupled to the electronic relief valve monitors vehicle speed and steering wheel turning rate change directs the solenoid relief valve to adjust the pressure of fluid displacing a movable cam ring within the pump to provide for greater fluid flow when evasive maneuvers may be required and lesser fluid flow when low steering efforts are needed, thus resulting in energy and fuel savings.
