Abstract
A valve apparatus for controlling the flow of two sources of a first fluid while preventing mixing of the two fluid sources is disclosed along with a system incorporating the same. The valve apparatus has a first valve chamber with a first valve mechanism for controlling the flow of a first fluid, such as a heated coolant, from a first source. A second valve chamber with a second valve mechanism controls the flow of a first fluid, such as a cooled coolant, from a second source, the first and second valve chambers being fluidly isolated from each other. At least one thermal actuator arranged within a control chamber or control manifold controls operation of the first and second valve mechanisms, the thermal actuator having a first activation temperature for controlling the first valve mechanism and a second activation temperature for controlling the second valve mechanism. A control fluid passing through the control chamber, or control manifold, dictates the operational settings of the first and second valve mechanisms, respectively. The control fluid may comprise a fluid to be heated and/or cooled, such as a transmission fluid.
