ABSTRACT:
A bimetal valve is disclosed which is adapted to open and close a fluid flow conduit, or change flow paths from one to another due to the snapping action of bimetal discs in response to ambient temperature changes of the valve. In a first embodiment, there is used a combination of two bimetal discs and a valve seat cooperative therewith, thereby opening and closing flow of fluid between two ports. In a second embodiment, there is used a combination of two bimetal discs and a hold-down plate having a valve body thereon, thereby opening and closing flow of fluid between the two ports. In a third embodiment, there is used a combination of three bimetal discs, a hold-down portion, a stem portion and a valve body, thereby changing flow paths from one to another. In a fourth embodiment, there is used a combination of three bimetal discs, a partition plate, a stem portion secured to a valve body, thereby also changing fluid paths.
