  • Patent number: 4651971
    Abstract: A direct acting valve assembly including a valve body and a guide tube attached thereto. An insert is secured within the guide tube and includes a central aperture and at least one filtering aperture. The valve body includes an annular surface between an annular inlet and a centrally located outlet, and an annular seal is positioned in a central recess in the bottom of the insert and adjacent the annular surface to provide a fluid tight seal therebetween. The guide tube receives a closure member which has one end tapered to a point positionable through the central aperture of the insert and adjacent the annular seal. A spring and solenoid combination is operable to move the closure member between a first position displaced from the annular seal and opening the valve and a second position adjacent the annular seal and sealing the central passageway.
