Abstract:
A fluid system for supplying a low pressure fluid and a high pressure fluid, the fluid system comprising:a first fluid pump configured to discharge a first fluid pump outlet flow, which is divisible into a first and a second portion; a fluid filter connected to said first fluid pump to receive said first portion of said first fluid pump outlet flow and configured to discharge a fluid filter outlet flow, which is divisible into a first and a second portion; a low pressure fluid accumulator connected to said fluid filter to receive said first portion of said fluid filter outlet flow; a priority valve connected to said first fluid pump to receive said second portion of said first fluid pump outlet flow, connected to said fluid filter to receive said second portion of said fluid filter outlet flow, and configured to discharge a priority valve outlet flow, said priority valve movable between a first position, which provides a first priority valve fluid flow path between said second portion of said first fluid pump outlet flow and said priority valve outlet flow, and a second position, which provides a second priority valve fluid flow path between said second portion of said fluid filter outlet flow and said priority valve outlet flow; a second fluid pump connected to said priority valve to receive said priority valve outlet flow and configured to discharge a second fluid pump outlet flow; and a high pressure fluid accumulator connected to said second fluid pump to receive said second fluid pump outlet flow.
