ABSTRACT:
A temperature-dependently actuated 3-port, 2-way valve 1 has a bimetallic disc 22 which closes either a valve seat 15, as shown, or a valve seat 14 when it snaps over into an upwardly domed position. The disc 22 is floatingly supported by two 3-legged springs 23 and 24 acting on its opposite sides. When, as shown, the disc is downwardly domed, only the upper spring 23 acts on the disc 22 and the legs of the lower spring 24 act against abutments 26. The reverse happens when the disc is upwardly domed. In this way the disc is always pressed against one seat or the other only by the appropriate spring and the closure force is independent of the flexural strength of the disc. The floating support of the disc 22 also ensures that it snaps over at or very near the correct operating temperature.
