DUAL MODE FUEL PUMP SYSTEM

摘要

A method and system providing a pressurized fluid includes a pump having a pump inlet and a pump outlet, the pump to provide a fluid flow, a bypass path to direct the fluid flow from the pump outlet to the pump inlet, a load path having a load path pressure, the load path including: a fluid accumulator to accumulate a fluid volume, and at least one load device, a bypass regulator valve in fluid communication with the pump outlet, the bypass path, and the load path, and a controller to direct the fluid flow to the load path in response to the load path pressure being less than a low load path threshold pressure via the bypass regulator valve and to direct the fluid flow to the bypass path in response to the load path pressure being greater than a high load path threshold pressure via the bypass regulator valve.

1. A system to provide a pressurized fluid, comprising:
a pump having a pump inlet and a pump outlet, the pump to provide a fluid flow; a bypass path to direct the fluid flow from the pump outlet to the pump inlet; a load path having a load path pressure, the load path including:
a fluid accumulator to accumulate a fluid volume; andat least one load device; a bypass regulator valve in fluid communication with the pump outlet, the bypass path, and the load path; and a controller to direct the fluid flow to the load path in response to the load path pressure being less than a low load path threshold pressure via the bypass regulator valve and to direct the fluid flow to the bypass path in response to the load path pressure being greater than a high load path threshold pressure via the bypass regulator valve.
