Abstract
A solenoid actuated valve device for electrically controlling the flow of fluid includes a body having an inlet port and an outlet port, a hollow core positioned within the body and having first and second axially spaced openings which provide fluid communication between said inlet and outlet ports and a cover member secured to one end of the body so that the core is supported by the body and the cover member for axial adjustment movement relative thereto. A bobbin is slidably mounted on the core and is provided with a valve portion for controlling the effective area of the first and second openings. A solenoid coil is provided for shifting the value in opposite directions. In the absence of electric current to the coil first and second springs maintain the bobbin in a position so that the valve portion thereof is located between the first and second openings in the coil so that one opening will be completely open and the other will be completely closed.
