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.
