Abstract

The filler cap (1) has a male screw thread which engages with a female thread in an aperture in the top of the radiator or heat exchanger (8). An O-ring seal (16) on a central portion of the cap engages with an inturned flange on the filler aperture. The cap incorporates an overpressure valve with a cylindrical inner portion (14) and an anti-rotation device between it and the outer part (12). The cap incorporates a control circuit (57) on a mounting plate (58), which can supply an electric current to a positive temperature coefficient heating resistor (56). This heats a membrane capsule (55) to load a spring and lock the cap in its closed position. The heater is switched on when the water temperature exceeds e.g. 89 degrees C.
