Abstract
The present invention relates to a rotatable cover which can be screwed or plugged on and is to be fastened on a stationary connection of a motor vehicle radiator or compensator reservoir of cooling and heating systems. The cover has a screw or plug cap and/or swivel cap and a rotatable engagement part in which a valve in the form of a combined overpressure/underpressure unit is arranged concentrically. The valve has a sealing member which produces a sealing connection with the stationary connection when the cover is applied. When the cover is positioned on the stationary connection, it is possible to prevent by means of a temperature-related control member removal, such as unscrewing or twisting of the cover. The temperature-related control member or a coupling part actuated by means of the temperature-related control member can be moved substantially radially between a coupling position and a release position. Consequently, a cover is produced which cannot be removed in cooling systems in which the temperature is still excessive, but which can be removed only when the excessive temperature has fallen completely, the cover nevertheless having a space-saving structure.
