| 1 | Variable displacement pump with electronic control | US09634975 | 2000-08-09 | US06408975B1 | 2002-06-25 | Leonard F. Bishop; Shawn P. Cap'ser; John D. Dalpiaz |
| A variable displacement pump 28 having an electronically modulated solenoid relief valve 100 for controlling fluid flow into the pump 28. An engine control module coupled to the electronic relief valve 100 monitors vehicle speed and steering wheel turning rate change directs the solenoid relief valve 100 to adjust the pressure of fluid displacing a movable cam ring 44 within the pump 28 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. | ||||||

A rotary vane pump comprising a stator (10) having a cylindrical surface; a rotor (2) which is positioned relative to the stator to define a fluid chamber between the rotor and the stator, the rotor being rotatable about a longitudinal axis (L) and having a number of radially extending slots therein; a vane (11) slidably mounted in each slot and biased towards the fluid chamber and into engagement with the surface of the stator, the vanes reciprocating in their respective slots as the rotor rotates about the stator; a first fluid passage (36) providing fluid at a first pressure from a fluid inlet to the fluid chamber; a second fluid passage taking fluid at a second pressure higher than the first pressure from the fluid chamber to a fluid outlet; and a electrically operated valve (15) positioned adjacent the fluid chamber and fluidly connecting the first and second fluid passages on detection of a predetermined condition. Energy saving design. |
