<p>IMPROVED CONTROL VALVE A temperature-responsive valve for controlling the flow of fluid substantially without being affected by the pressure of or the turbulence generated by said fluid, comprises a housing having a chamber therein, an inlet port communicating with said outlet port communicating with said chamber, a temperature deflectable partition having an aperture and a tube. The tube extends from said inlet port past said aperture when the deflectable partition is in the position permitting a full flow of fluid. When the temperature of the fluid transmitted to said partition reaches a first predetermined value, the deflectable partition snaps to restrict with its surface the flow of fluid into said outlet port and remains in that position until the temperature of said fluid transmitted to said partition reaches a second predetermined value. The deflectable partition then snaps to permit the full flow of fluid into said outlet port. The tube substantially eliminates the effect of the pressure and the turbulence of the fluid upon temperature at which the deflectable partition snaps to restrict the flow of fluid. The temperature-responsive valve is especially useful in showers for protecting users from discomfort or scalding in the event the temperature of the shower water rises above the desired value.</p> |
