  • Patent number: 4707279
    Abstract: A self-seating valve with compressive release is provided. The invention includes a tubular valve body which is capable of elastic axial compression by means of the compression of circumferential compression rings. A diametrical bar supports a longitudinal valve stem at the end of which is affixed a valve element adjacent to a valve seat. Upon the axial compression of the valve body, the valve stem is axially displaced thereby lifting the valve from the valve seat.
