Abstract:
The present invention provides a fluid control system and associated methods. The fluid control system includes a source of a pressurized fluid and a first spool valve having at least two positions, wherein the first spool valve is connected in fluid communication with the source of the pressurized fluid. The fluid control system further includes a second spool valve having at least two positions, wherein the second spool valve is connected in fluid communication with the first spool valve and the source of the pressurized fluid. When the first spool valve is in a first position and the second spool valve is in a second position, a first portion of the pressurized fluid is directed from the source of the pressurized fluid to the second spool valve via the first spool valve.
