摘要： A normally opened solenoid valve includes: a coil; a fixed core; a movable core; a valve seat located at one of openings of a through hole formed in the fixed core; and a valve body inserted into the through hole. The valve body includes: a shaft part inserted into the through hole and pressed by the movable core; a valve part seated on or separated from the valve seat; and a connection part configured to connect the shaft part with the valve part. The connection part includes a conical portion increased in diameter toward the shaft part from the valve part. A plurality of reduced thickness portions, each having a concave shape as viewed in an axial direction, are formed in the conical portion. The reduced thickness portions are located at equal intervals in a circumferential direction of the conical portion.

摘要： A normally open electromagnetic valve includes: a fixed core; a movable core which is driven when excited; a valve seat member in the fixed core and having a funnel-shaped valve seat surface; a valve member disposed so that the valve member advances or retreats together with the movable core with one end of the valve member kept in contact with the movable core, and that the other end of the valve member closes or opens a flow passage by coming into contact with or separates from the valve seat surface; and a return spring. The fixed core has a cylindrical holding hole. The valve member advances or retreats being guided by the holding hole in sliding contact with the holding hole. The movable core has a projection which projects toward the fixed core and which is directly inserted into the holding hole.
