Patent ID: 7744007

Claim:
A thermostatic mixing valve, comprising: an elongated valve body defining a cold fluid inlet that is configured to be connected in fluid communication with a cold fluid source, a hot fluid inlet that is configured to be connected in fluid communication with a hot fluid source, and a mix fluid outlet in fluid communication with the cold fluid inlet, the hot fluid inlet, and a mixing chamber disposed within the valve body, said valve body having an in-line configuration wherein the hot fluid inlet, mixing chamber, and mix fluid outlet are substantially axially aligned along a longitudinal axis of the elongated valve body; a fluid flow regulator disposed along the longitudinal axis within the elongated valve body for adjusting the relative flow of cold and hot fluid injected into the mixing chamber; and temperature selection means accessible from outside of the elongated valve body for allowing a user to adjust the temperature of fluid contained within the mixing chamber, wherein the temperature selection means is configured to engage the fluid flow regulator to move the relative position of the fluid flow regulator coextensively along the longitudinal axis of the elongated valve body.
