摘要：
A poppet valve is disclosed that include a valve body, a poppet guide disposed inside the valve body so as to form a 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.
