Abstract
A pilot valve is provided with a conical first contact surface, and a pilot valve seat is provided with an annular second contact surface of which an initial contact portion with respect to the first contact surface has a circular-arc cross-section. The first contact surface is formed of a resin with elasticity, and the second contact surface is formed of metal. When a pressure-contact load is small, the first contact surface and the second contact surface come into line-contact with each other. When a pressure-contact load increases, the first contact surface and the second contact surface come into plane-contact with each other.
