Latest Patents
Rita holds a patent for a "Soft seal poppet type check valve." This invention features a check valve that typically blocks fluid flow from a bore to a passage. It includes a spring that normally holds a ball in sealing engagement with a valve seat, forming a primary metal-to-metal hard seal. Additionally, another spring holds a poppet in engagement with a second valve seat, allowing an annular protuberance on the poppet to sealingly engage a resilient seal. This design provides a more positive secondary soft seat seal. The innovative mechanism ensures that the poppet is unseated from the valve seat by a piston stem before the ball is unseated, allowing the soft seal to open at essentially zero flow conditions. Rita's patent represents a significant advancement in check valve technology.
