ABSTRACT:
A check valve apparatus is provided for use in connecting two fluid passageways, such as between which have multiple fluid passageways. The check valve manifolds and servovalves apparatus includes a poppet seal and a spring which engages and biases the poppet outward in sealing engagement with a portion of the wall surrounding the fluid passageway entrance and the entrance is effective for receiving an extension of the other fluid passage so that the extension engages and biases the poppet open. Mounted on the poppet is a means for sealing and retaining said poppet within the cavity which in the preferred mode is an elastomeric O ring restrainedly mounted within an annular channel circumscribing the poppet. One embodiment contemplates servovalve including a casing having extensions which comprise a filter.
