  • Poppet valve with pivotable seal
    Patent number: 11873915
    Abstract: A poppet valve apparatus has a valve body with an aperture rimmed by a first sealing surface, and a valve stem with an axially oriented cup at its tip with a spring disposed within the cup. The valve plate includes a sealing surface at its perimeter and also has a central pocket which receives a spheroid. The valve stem passes through a collar which is affixed to the valve plate to trap the spheroid beneath the spring so that the plate is pivotably coupled to the valve stem and also tolerates radial and lateral excursion to allow the valve plate to self-align and seal within the valve seat.
