摘要：
A poppet valve is provided with a seat portion which has a conical inner peripheral surface with a center axis, and a conical portion which is displaced along the center axis inside the seat portion, forms a flow passage having an annular cross-section between the conical portion and the seat portion and is supported at a position concentric with the seat portion. An effect of rectifying fluid flowing in the flow passage is thereby obtained and the generation of noise is prevented.
