Abstract (en)
[origin: WO02095200A1] A closure cap (10) for a fixed neck of a motor vehicle radiator is provided with a cap outer part (12), which comprises a closure element (17) that can be joined to the reservoir neck, and comprises a grip element (13) that is held in a manner that permits it to be twisted in relation to the closure element. A torsional stop (20) is provided between said closure element and grip element. The aim of the invention is to provide a closure cap of the aforementioned type with safety-relevant functions of the torsional stop and of the reduction of excess pressure in a structurally simple manner whereby permitting them to be exactly adapted to one another. To this end, an actuator (15) that can be expanded when subjected to heat is provided both for axially engaging and disengaging the coupling insert (46) of the torsional stop (20) as well as for adjusting the pretension with which the valve body (22) of the valve arrangement (11) is pressed against the sealing seat (21).
