Abstract:
A thermostatic mixing valve configured to produce a mixed fluid substantially of a particular temperature from the mixing of a first fluid of a temperature higher than or equal to the particular temperature and of a second fluid of a temperature lower than or equal to the particular temperature, and comprising:a valve body including a first fluid inlet, a second fluid inlet, and a mixed fluid outlet; anda valve member configured to control the rate of flow of at least the first fluid, the valve member comprising:a thermostatic control device in communication with the mixed fluid;a shuttle coupled to the thermostatic control device, configured for movement within a liner, and oriented to adjustably engage the flow of at least the first fluid through at least one opening within a wall of the liner, the direction of movement of the shuttle with respect to the liner defining the major longitudinal axis of the thermostatic mixing valve, the direction of flow of the first fluid being at least partially transverse with respect to the major longitudinal axis of the valve; andan auxiliary valve seat configured to coact with the shuttle so that engagement of the shuttle and the auxiliary valve seat obstructs the flow of at least the first fluid upon a failure of the thermostatic control device.
