PRESSURE-REDUCING VALVE

摘要

Provided is a pressure-reducing valve, comprising a valve chamber, a pressure control chamber, a partition member which has a communication hole, and a valve body. The partition member comprises the communication hole and a valve seat. The valve body comprises a main body part and a rod part. The valve seat comprises a plurality of inclined surfaces which have different angles of inclination with respect to the center axis of the valve body. The circumference wall of the communication hole and the valve seat are connected with a connection part. The angles of inclination of the valve seat change incrementally such that the valve seat and the valve body make contact at a position more distant in the radial direction from the center axis of the valve body toward the outer side than the connection part.
