A temperature responsive valve has an inlet 5 and two outlets 9, 10 and a valve member 6, 7 movable to block one or other of said outlets. The valve member has an expansion part which when heated expands against a spring 8 to cause the valve member to move to a position blocking outlet 9. When cool, the valve member blocks outlet 10. The expansion part may contain material which undergoes a transition when heated, such as wax. |
