ABSTRACT:
The invention pertains to a self-sealing conduit fitting of the ball valve type. A spherical ball valve having a diametrical bore is pivotally supported within a fitting passage and operated by a pivot axis eccentrically related to the valve center. The pivot is restrained against axial movement, but is radially displaceable, and biasing means within the fitting body bias the ball valve axially into engagement with an annular valve seat also capable of axial displacement within the fitting. The ball valve pivot causes the ball valve to rotate between opened and closed positions upon axial displacement of the ball valve by its valve seat, or under the influence of the biasing means. Stop means determining the axial position of the valve seat maintains the ball valve in a closed condition when the fitting is disconnected.
