Abstract
A valve mechanism which opens in response to a high temperature includes a stopper positionable at a closed position that blocks the flow of water in a cylindrical body attached to a water supply pipe. A stopper support permits the stopper to be movable from the closed position to an open position, wherein pressure of the water in the supply pipe tends to move the stopper from the closed position to the open position. A locking unit is positionable to lock the support in a position wherein the stopper blocks the channel, and has an inclined surface inclined obliquely to the water flow direction. A heat sensitive section blocks movement of the locking unit from the locking position and includes a heat sensitive portion responsive to the temperature of an environment of the valve mechanism.
