ABSTRACT:
A check valve for use in an oral inflation valve has an articulated connection between the valve head and valve stem. The valve stem has a trailing end in the form of a spherical ball and a socket carried by the valve head rotatably receives the ball so that the valve head may skew about an axis of articulation when the valve is open. The trailing end of the valve body is flat and the mating surface of the valve head is flat so that the head seats squarely on the seat when the valve is in repose. The flat trailing end of the valve body is coincident with the axis of articulation. In a second embodiment, the ball and socket are not spherical, but are of frusto-conical configuration to facilitate assembly of the device.
