Abstract
A valve housing has a bottomed hollow cylindrical main body and a boss projecting from and smaller in diameter than the main body. The main body has a tapered surface circumferentially along a joint where a side wall and a bottom wall of the main body are joined to each other. A plurality of inlet ports are defined in the tapered surface. The boss has an outlet port for discharging a fluid introduced into the main body. When a valve head coupled to the movable member is displaced and a seating ridge of a resilient member mounted on the valve head is seated on a valve seat surface, the inlet ports and the outlet port are brought out of fluid communication with each other.
