Dual pressure fluid system and method of use

Image Number 3 for United States Patent #6742503.

A fluid system for supplying low and high pressure fluid is provided. A first pump discharges a first pump flow. A filter receives a first portion of the first pump flow and discharges a filter flow. A first accumulator receives a first portion of the filter flow. A valve receives a second portion of the first pump flow and a second portion of the filter flow, and discharges a valve flow. The valve is movable between a first position, providing a first flow path between the second portion of the first pump flow and the valve flow, and a second position, providing a second flow path between the second portion of the filter flow and the valve flow. A second pump receives the valve flow and discharges a second pump flow. A second accumulator receives the second pump flow.
