Beim Ausfuhrungsbeispiel der Figur 1, bei dem der Antrieb druckgesteuert ist, ist das Ubertragungselement 54 als Hohlstab mit einer Durchgangsbohrung ausgebildet. Der Hohlstab 54 ist dem unteren Raum 47 abgewandt mit einem Flansch 57 versehen, der auf dem Zwischenboden 21 des Verschlusselementes 17 aufliegt. Am Flansch 57 ist der Sperrplatte 27 zugewandt eine den Antrieb 14 bildende Membran 50 außenumfangsseitig druckdicht eingespannt gehalten. Die das Behälterinnere gegenüber dem Griffelement 18 druckdicht abdichtende Membran liegt in der in Figur 1 dargestellten drucklosen Ausgangsstellung mittig auf dem Flansch 57 auf und überdeckt die Durchgangsbohrung 56. Die Membran 50 ist an einem Ringbereich zwischen dem genannten mittigen Bereich 51 und ihrem Einspannbereich mit einer Ringwölbung 52 versehen, die die axiale Auslenkung des mittigen Bereich 51 der Membran 50 ermöglicht. Der mittige Bereich 51 der Membran 50 ist durch die Wirkung der Druckfeder auf die Sperrplatte 27 auf den Flansch 57 gedrückt.In the exemplary embodiment in FIG. 1, in which the drive is pressure-controlled, the transmission element 54 is designed as a hollow rod with a through hole. The hollow rod 54 facing away from the lower space 47 is provided with a flange 57 which rests on the intermediate floor 21 of the closure element 17. On the flange 57, the locking plate 27 faces a membrane forming the drive 14 50 clamped pressure-tight on the outer circumference. In the pressure-free starting position shown in FIG. 1, the membrane that seals the inside of the container from the handle element 18 in a pressure-tight manner lies centrally on the flange 57 and covers the through hole 56. The membrane 50 is at an annular region between the central region 51 mentioned and its clamping region with an annular curvature 52 provided, which enables the axial deflection of the central region 51 of the membrane 50. The central region 51 of the membrane 50 is pressed onto the flange 57 by the action of the compression spring on the locking plate 27.
Beim Ausführungsbeispiel der Figur 2 ist der Antrieb 114 durch eine Thermokapsel 150 gebildet, die außenrandseitig auf dem Zwischenboden 121 des Verschlusselements 117 aufliegt und auf der mittig der mittige Bereich der Sperrplatte 127 unter der Wirkung der Druckfeder 126 aufliegt. Die Thermokapsel 150 jetzt bodenseitig in den endseitig verschlossenen thermischen Übertragungshohlstab 154 über. Thermokapsel 150 und Hohlstab 154 beinhalten einen Dehnstoff, der sich unter dem Einfluss von Wärme bei Temperaturerhöhung ausdehnt. Der Thermostab 154 kann auch als Vollstab ausgebildet sein und die Wärme vom Behälterinneren auf den Dehnstoff in der Thermokapsel 150 übertragen .In the exemplary embodiment in FIG. 2, the drive 114 is formed by a thermal capsule 150 which lies on the outer edge side on the intermediate floor 121 of the closure element 117 and on which the central region of the locking plate 127 rests under the action of the compression spring 126.

Der Unterdruckventilkörper 13, 113 gemäß den beiden Ausführungsformen ist an der Unterseite des Zwischenbodens 38, 138 des Ventiltopfes 36, 136 an einer Stelle des die mittige Öffnung 39, 139 umgebenden Ringbereichs exzentrisch zur Längsachse 55, 155 des Verschlussdeckels 10, 110 angeordnet. Der Unterdruckventilkörper 13, 113, der unterschiedliche Formen besitzen kann, ist innerhalb einer Nebenkammer 60, 160 angeordnet, die über eine Öffnung 61, 161 im Zwischenboden 38, 138 mit der Überdruckventilkammer 37 in Verbindung steht. Die Nebenkammer 60, 160 ist etwa topfförmig, wobei die offene Seite zum Behälterinneren hinweist. Innerhalb der Nebenkammer 60, 160 ist eine horizontale Zwischenplatte 62, 162 vorgesehen, in deren Bohrung der Unterdruckventilkörper 13, 113 gehalten ist. Die Unterseite der Zwischenplatte 62, 162 ist mit einer Dichtscheibe 64, 164 versehen, an der derThe vacuum valve body 13, 113 according to the two embodiments is on the underside of the intermediate floor 38, 138 of the valve cup 36, 136 at a location of the ring area surrounding the central opening 39, 139 eccentrically to the longitudinal axis 55, 155 of the closure cover 10, 110. The vacuum valve body 13, 113, which can have different shapes, is arranged within a secondary chamber 60, 160, which communicates with the pressure valve chamber 37 via an opening 61, 161 in the intermediate floor 38, 138. The secondary chamber 60, 160 is approximately pot-shaped, the open side pointing towards the inside of the container. A horizontal intermediate plate 62, 162 is provided within the secondary chamber 60, 160, in whose bore the vacuum valve body 13, 113 is held. The underside of the intermediate plate 62, 162 is provided with a sealing washer 64, 164 on which the
Unterdruckventilkörper 13 mit seiner Ringdichtfläche 65, 165 unter der Wirkung der Druckfeder 66, 166 aufsitzt, die in dem der Öffnung 61, 161 im Zwischenboden 38, 138 zugewandten Nebenkammerteil zwischen dem Unterdruckventilkörper 13, 113 und der Zwischenplatte 62, 162 angeordnet ist. Auf diese Weise kann bei im Behälterinneren herrschendem Unterdruck der Unterdruckventilkörper 13, 113 von der Dichtscheibe 64, 164 entgegen der Wirkung der Druckfeder 66, 166 abgehoben werden, so dass ein Druckausgleich stattfindet.Vacuum valve body 13 rests with its annular sealing surface 65, 165 under the action of compression spring 66, 166, which is arranged in the secondary chamber part facing opening 61, 161 in intermediate floor 38, 138 between vacuum valve body 13, 113 and intermediate plate 62, 162. In this way, the vacuum valve body 13, 113 can be lifted from the sealing disk 64, 164 against the action of the compression spring 66, 166, so that a pressure compensation takes place.
Während des Motorbetriebs wird sich die Kühlflüssigkeit erwärmen, so dass im Behälter die Temperatur bzw. der Druck ansteigt. Durch das Übertragungselement 54, 154, das mit dem Antrieb 14, 114 verbunden ist, wird bei Druckerhöhung gemäß Figur 1, linker Halbschnitt, die Membran 50 ausgelenkt und entgegen der Wirkung der Druckfeder 44 in Richtung des Pfeiles B axial bewegt, während sich beim Ausführungsbeispiel gemäß Figur 2, linker Halbschnitt, aufgrund der Temperaturerhöhung der Dehnstoff ausdehnt und sich die Thermokapsel 150 in Richtung des Pfeiles B entgegen der Wirkung der Druckfeder 144 axial dehnt. In beiden Fällen wird die Sperrplatte 27, 127 in Richtung des Pfeiles B unter Zusammendrücken der Druckfeder 44, 144 angehoben, so dass die Klauen 29, 129 der Verdrehsicherung 19, 119 bzw. der Sperrplatte 27, 127 aus den Nuten 31, 131 des Verschlusselements 17, 117 freikommen. In diesem Zustand ist die drehfeste Verbindung zwischen Verschlusselement 17, 117 und Griffelement 18, 118 aufgehoben, so dass das Griffelement 18, 118 gegenüber dem Verschlusselement 17, 117 hohl dreht. Diese Leerlaufverbindung zwischen Griffelement 18, 118 und Verschlusselement 17, 117 verhindert ein Abschrauben des Verschlussdeckels 10, 110 vom Behälterstutzen. Ergeben sich wieder normale Ausgangswerte von Druck bzw. Temperatur im Behälterinneren, gelangt die Verdrehsicherung 19, 119 unter der Wirkung der Druckfeder 44, 144 wieder in ihre Ausgangsstellung, so dass der Verschlussdeckel 10, 110 durch die drehfeste Verbindung von Griffelement 18, 118 und Verschlusselement 17, 117 wieder abgeschraubt werden kann. The coolant will heat up while the engine is running, causing the temperature or pressure in the tank to rise. Through the transmission element 54, 154, which with the Drive 14, 114 is connected, the diaphragm 50 is deflected when the pressure increases according to FIG. 1, left half-section, and is moved axially against the action of the compression spring 44 in the direction of arrow B, while in the embodiment according to FIG. 2, left half-section, due to the temperature increase the expansion material expands and the thermal capsule 150 axially expands in the direction of arrow B against the action of the compression spring 144. In both cases, the locking plate 27, 127 is raised in the direction of arrow B by compressing the compression spring 44, 144, so that the claws 29, 129 of the anti-rotation device 19, 119 or the locking plate 27, 127 out of the grooves 31, 131 of the closure element 17, 117 are released. In this state, the rotationally fixed connection between the closure element 17, 117 and the grip element 18, 118 is canceled, so that the grip element 18, 118 rotates hollowly with respect to the closure element 17, 117. This idle connection between handle element 18, 118 and closure element 17, 117 prevents the closure cover 10, 110 from being unscrewed from the container neck. If normal output values of pressure or temperature in the interior of the container are again obtained, the anti-rotation device 19, 119 returns to its initial position under the action of the compression spring 44, 144, so that the closure cover 10, 110 due to the rotationally fixed connection of the grip element 18, 118 and the closure element 17, 117 can be unscrewed again.
