A thermostatic mixing valve for the mixing of a first and second fluids is disclosed. The thermostatic mixing valve includes a valve body having first and second inlets, and a mixed fluid outlet. The thermostatic mixing valve includes a valve member configured to control the rate of flow of at least the first fluid. The member includes a thermostat in communication with the mixed fluid and a shuttle coupled to the thermostat, configured for movement within a liner, and oriented to adjustably engage the flow of the first fluid through an opening within a wall of the liner, the direction of flow of the first fluid being at least partially transverse with respect to the shuttle. A fluid inlet may include a check valve configured to prevent fluid from flowing out of the valve through the inlet.

1. An apparatus for a thermostatic mixing valve having a body and a thermostat, comprising: a cylindrical liner adapted and configured to be located within a cavity of the body, said liner having a cylindrical wall extending between first and opposing second ends, a first end being open and the second end including a radially extending end wall, said cylindrical wall including first and second flow passages extending therethrough and being spaced apart between the first end and the end wall, said cylindrical wall including a seal groove located between said first and second flow passages;a shuttle receivable with the inner diameter of said liner, the position of said shuttle within said liner being established at least in part by the thermostat, said shuttle having a first end with a radially extending end wall, said shuttle having an interior pocket and a third flow passage from the interior pocket to the exterior of said shuttle;a spring for biasing said shuttle apart from said liner;a cylindrical valve seat having two ends and a fourth flow passage therebetween, one end including an outwardly radially extending surface adapted and configured for abutting contact with the end wall of said shuttle. 2. The apparatus of claim 1 wherein the second end of said valve seat includes a seal groove for sealing against the inner diameter of said liner. 3. The apparatus of claim 1 wherein said shuttle has an outer diameter receivable with the inner diameter of said liner, and the outer diameter includes a seal groove. 4. The apparatus of claim 1 wherein the second flow passage is located proximate the second end of said liner, said shuttle has a second end opposite of the first end, and the second end substantially obstructs flow through the second passage when the second end of said shuttle contacts the end wall of said liner. 5. The apparatus of claim 1 wherein said spring is a first spring, and which further comprises a second spring for biasing said shuttle toward the end wall of said liner. 6. The apparatus of claim 1 wherein the first flow passage is located between the first end of said liner and the seal groove of said liner, said valve seat includes a wall and a fifth flow passage through the wall, the fifth flow passage being configured and located to receive flow from the first flow passage. 7. The apparatus of claim 1 wherein said valve seat includes an outer cylindrical surface in fixed contact with the inner diameter of said liner, and wherein the fourth flow passage extends axially between the two ends of said valve seat. 8. The apparatus of claim 1 wherein the end of said valve seat is a first end, and wherein said valve seat further includes a second end including a second outwardly radially extending surface adapted and configured for abutting contact with the first end of said liner. 9. The mixing valve of claim 1 wherein the third flow passage extends through the radially extending end wall of said shuttle. 10. In a thermostatic mixing valve configured to produce a mixed fluid substantially of a particular temperature from a first fluid of a temperature higher than the particular temperature and a second fluid of a temperature lower than the particular temperature, the mixing valve including a valve body having a first fluid inlet, a second fluid inlet, and a mixed fluid outlet, and a thermostatic control device in fluid communication with the mixed fluid, the improvement comprising: a cylindrical liner adapted and configured to be located within a cavity of the body, said liner having a cylindrical wall extending between first and second opposing ends, a first end being opened and the second end including a radially extending end wall, said cylindrical wall including first and second flow passages extending therethrough and being spaced apart between the first end and the end wall, said cylindrical wall including a seal groove located between said first and second flow passages, said cylindrical wall having an inner diameter;a shuttle receivable with the inner diameter of said liner, the position of said shuttle within said liner being established at least in part by the thermostat, said shuttle having a first end with a radially extending end wall, said shuttle having an interior pocket and a third flow passage from the interior pocket to the exterior of said shuttle;a spring for biasing said shuttle apart from said liner;a cylindrical valve seat having two ends, one end including an outwardly radially extending surface adapted and configured for abutting contact with the end wall of said shuttle, the other end of said valve seat being receivable within the inner diameter of said liner. 11.
