ABSTRACT:
A simple bypass valve device for carrying a winter thermostat in an automotive cooling system obviates the need for seasonal thermostat changes. The valve device includes a casing defined by identical end portions and a ring rotatably mounted between the end portions for carrying the winter thermostat. The end portions and ring contain passages which can be placed in fluid communication in spring or summer by rotating the ring so that the winter thermostat is bypassed, and, in autumn or winter, removed from fluid communication by reverse rotation of the ring so that the winter thermostat is in the flow path of the coolant, which cannot flow therearound.
