Abstract:
A control valve system comprising:a housing having an inlet, a first output, and a second output; a valve positionable in at least a first position where fluid communication is established between said inlet and said first output, a second position where fluid communication is established between said inlet and said second output, and a third position where fluid communication is generally prevented between said inlet and said first output or said second output, said valve being biased into said first position by a biasing force; a solenoid valve assembly coupled in fluid communication with said inlet, said solenoid valve assembly being positionable in an actuated position where fluid communication is established with said inlet to move said valve from said first position to said second position and a deactuated position; and a piston extendable against said valve to counteract said biasing force for alternating said valve between said second position and said third position in response to fluid pressure within said first output.
