  • Poppet valve with sloped purge holes and method for reducing a pressure force therein
    Patent number: 8453670
    Abstract: A poppet valve is disclosed that includes a valve body, a poppet guide disposed inside the valve body so as to form a flow passage from an inlet to an outlet of the valve, a poppet shutter disposed inside the poppet guide, and a biasing member to bias the poppet shutter away from the poppet guide toward an inside surface of the flow inlet so as to block the flow passage. The poppet valve further includes at least one discharge hole placing an inner chamber of the poppet guide in flow communication with a region of low static pressure of the flow passage. A method for reducing a closing pressure force acting on a poppet shutter of a poppet valve is also disclosed.
    Type: Grant
    Filed: July 31, 2008
    Date of Patent: June 4, 2013
    Assignee: Nuovo Pignone, S.p.A.
    Inventors: Stefano Francini, Nicola Campo, Michele Bianchini
  • Poppet valve with diverging-converging flow passage and method to reduce total pressure loss
    Patent number: 8136547
    Abstract: A poppet valve is disclosed that include a valve body, a poppet guide disposed inside the valve body so as to form a flow passage from a flow inlet to a flow outlet of the valve, a poppet shutter disposed inside the poppet guide, and a converging-diverging flow passage formed by a portion of an outer surface of the poppet shutter and a corresponding portion of an inner surface of valve body. A method for reducing a closing pressure force acting on a poppet shutter of a poppet valve is also disclosed.
