Abstract

See full text

A control valve includes a valve body, which defines first, second, and third valve passageways. The valve body also defines a supply passageway. The control valve includes a first spool movable relative to the valve body between first and second positions. The control valve includes a second spool movable relative to the valve body between open and closed positions. The supply passageway is in fluid communication with the first valve passageway when the first spool is in the first position. The supply passageway is in fluid communication with the second valve passageway when the first spool is in the second position. The supply passageway is in fluid communication with the third valve passageway when the second spool is in the open position. The second spool precludes fluid flow between the supply passageway and the third valve passageway when the second spool is in the closed position.
