Description

Die vorliegende Erfindung bezieht sich auf einen Verschlussdeckel für einen ortsfesten Stutzen eines Behälters, insbesondere Kraftfahrzeugkühlers, nach dem Oberbegriff des Anspruchs 1, (siehe WO 95/32904 ).The present invention relates to a closure cap for a stationary neck of a container, in particular motor vehicle radiator, according to the preamble of claim 1, (see WO 95/32904 ).

Bei einem derartigen aus der DE 197 53 597 A1 bekannten Verschlussdeckel ist die Verdrehsicherung zwischen Verschlusselement und Griffelement durch einen axialen Kupplungsbolzen gebildet, der von einer temperaturabhängig arbeitenden Federanordnung beaufschlagt ist.In such a from the DE 197 53 597 A1 Known closure lid, the rotation between closure element and grip element is formed by an axial coupling pin, which is acted upon by a temperature-dependent working spring arrangement.

Bei einem aus der DE 199 23 775 A1 des weiteren bekannten Verschlussdeckel ist die Verdrehsicherung durch einen axial bewegbaren und innerhalb des Griffelements angeordneten Bügel gebildet, der von einem thermischen Antrieb in form eines Dehnstoffelementes betätigt ist. In beiden bekannten Fällen ist es schwierig, die konkret im Behälter bestehende Wärme ohne größere Temperaturverluste an die durch Wärme beeinflussbare Verdrehsicherung zu bringen. Dies ist nicht zuletzt durch die im Wege zwischen Behälterinnerraum und Verdrehsicherung angeordnete Ventilanordnung in Form eines Überdruck- und eines Unterdruckventils schwierig zu gestalten. Entsprechendes gilt auch bei solchen Verschlussdeckeln, die, wie bereits vorgeschlagen, mit einer Druckgesteuerten Verdrehsicherung arbeiten.At one of the DE 199 23 775 A1 Further known closure lid, the rotation is formed by an axially movable and arranged within the handle member bracket, which is actuated by a thermal drive in the form of a Dehnstoffelementes. In both known cases, it is difficult to bring the existing concrete heat in the container without major temperature losses of the heat-influenceable against rotation. This is not least due to the valve arrangement in the form of an overpressure valve and a vacuum valve, which is arranged in the way between the container interior space and the anti-rotation device. The same applies to such caps, which, as already proposed, work with a pressure-controlled anti-rotation.

Aufgabe der vorliegenden Erfindung ist es deshalb, einen Verschlussdeckel für einen ortsfesten Stutzen eines Behälters, insbesondere Kraftfahrzeugkühlers, der eingangs genannten Art zu schaffen, an dessen Verdrehsicherung bzw. deren Antrieb in einfacherer Weise und ohne unzulässig hohe Verluste die im Behälterinneren vorhandene Temperatur bzw. der im Behälterinneren vorhandene Druck herangebracht werden kann.The object of the present invention is therefore to provide a closure cap for a stationary neck of a container, in particular motor vehicle radiator, of the aforementioned type, at its rotation or their drive can be brought in a simpler manner and without unduly high losses present in the container interior temperature or existing in the container interior pressure.

Durch die erfindungsgemäßen Maßnahmen ist erreicht, dass das temperaturabhängig oder druckabhängig arbeitende Antriebselement beispielsweise in Form einer Dehnstoffkapsel bzw. einer Membran, die im Behälterinneren herrschende Temperatur bzw. den im Behälterinneren herrschenden Druck unmittelbar, ohne Verluste und unverzögert aufnehmen kann. Die Übertragung der Bewegung des im wesentlichen unmittelbar im Behälterinneren angeordneten Antriebs auf die Verdrehsicherung ist in konstruktiv einfacher Weise und unmittelbar möglich, wobei gleichzeitig erreicht ist, dass die Überdruck/Unterdruckventilanordnung in der bekannten Weise im Deckelinnenteil verbleiben kann.The inventive measures it is achieved that the temperature-dependent or pressure-dependent driving element, for example in the form of a Dehnstoffkapsel or a membrane, the temperature prevailing inside the container or the pressure prevailing in the container interior directly, without losses and without delay. The transmission of the movement of the arranged substantially directly in the container interior drive on the anti-rotation is in a structurally simple manner and immediately possible, which is achieved at the same time that the pressure / vacuum valve assembly can remain in the known manner in the inner lid.

Mit den Merkmalen des Anspruchs 4 und/oder 5 ist eine konstruktiv einfache und unmittelbar zum Behälterinneren weisende Anordnung des Antriebs gegeben. Dabei ist es für eine Unmittelbarkeit des Vorhandenseins der Verhältnisse im Behälterinneren an den Antrieb zweckmäßig, die Merkmale nach Anspruch 7 und/oder 8 vorzusehen.With the features of claim 4 and / or 5, a structurally simple and directly to the container interior facing arrangement of the drive is given. It is expedient for an immediacy of the presence of the conditions in the container interior to the drive to provide the features of claim 7 and / or 8.

Während des Motorbetriebs wird sich die Kühlflüssigkeit erwärmen, so dass im Behälter die Temperatur bzw. der Druck ansteigt. Durch die unmittelbar Anordnung des Antriebs 14 bzw. 114 im Behälterinneren wird bei Druckerhöhung gemäß Figur 1 bzw. Figur 2 jeweils linker Halbschnitt die Membran 50 ausgelenkt und entgegen der Wirkung der auf die Verdrehsicherung wirkenden Druckfeder 44, 44' in Richtung des Pfeiles B axial bewegt, wobei diese axiale Bewegung auf die Bewegungsübertragungsvorrichtung 70, 70' und damit auf die Sperrplatte 27 bzw. den Sperrhebel 27' übertragen wird. Beim Ausführungsbeispiel der Figur 3 und der Variante der Figur 4, jeweils linker Halbschnitt, wird aufgrund der Temperaturerhöhung der Dehnstoff ausgedehnt, so dass sich die Thermokapsel 150 in Richtung des Pfeiles B ebenfalls entgegen der auf die Verdrehsicherung wirkenden Druckfeder 144, 144' axial dehnt. Auch hier wird diese Dehnungsbewegung der Thermokapsel 150 über die Bewegungsübertragungsvorrichtung 170 bzw. 170' auf die Sperrplatte 127 bzw. den Sperrhebel 127' übertragen. In beiden Fällen wird die Sperrplatte 27, 127 bzw. der Sperrhebel 27', 127' in Richtung des Pfeiles B unter Zusammendrücken der Druckfeder 44, 44', 144' angehoben, so dass die Klauen 29, 129 bzw. Sperrfinger 29', 129' der Sperrplatte 27, 127 bzw. des Sperrhebels 27', 127' aus den Nuten 31, 131 bzw. den Zwischenräumen zwischen jeweils zwei Rastnasen 31', 131' freikommen.

Diese Lehrlaufverbindung zwischen Griffelement und Verschlusselement verhindert ein Abschrauben des Verschlussdeckels 10, 110 bzw. 10', 110' vom Behälterstutzen. Ergeben sich wieder normale Ausgangswerte von Druck- bzw. Temperatur im Behälterinneren, gelangt die Verdrehsicherung 19, 119 bzw. 19', 119' unter der Wirkung der Druckfeder 44, 144 bzw. 44', 144' wieder in ihre Ausgangsstellung, so dass der Verschlussdeckel durch die drehfeste Verbindung von Griffelement und Verschlusselement wieder abgeschraubt werden kann.During engine operation, the coolant will heat up, causing the temperature or pressure in the reservoir to rise. Due to the immediate arrangement of the drive 14 or 114 in the container interior, the membrane 50 is deflected at pressure increase according to Figure 1 and Figure 2 each left half section and axially against the action of acting on the rotation pressure spring 44, 44 'in the direction of arrow B. , this axial movement is transmitted to the motion transmission device 70, 70 'and thus to the locking plate 27 and the locking lever 27'. In the embodiment of Figure 3 and the variant of Figure 4, each left half section, the expansion material is extended due to the increase in temperature, so that the thermal capsule 150 in the direction of arrow B also opposite the compression spring 144, 144 'acting on the anti-twist device axially stretches. Again, this expansion movement of the thermal capsule 150 via the motion transmission device 170 and 170 'on the locking plate 127 and the locking lever 127' transmitted. In both cases, the locking plate 27, 127 and the locking lever 27 ', 127' in the direction of arrow B under compression of the compression spring 44, 44 ', 144' is raised, so that the jaws 29, 129 and locking fingers 29 ', 129 'of the locking plate 27, 127 and the locking lever 27', 127 'from the grooves 31, 131 and the spaces between each two locking lugs 31', 131 'free. In this state (each left half section), the rotationally fixed connection between the closure element 17, 117 and 17 ', 117' and handle member 18, 118 and 18 ', 118' repealed, so that the handle member rotates hollow relative to the closure element. This training connection between the handle element and closure element prevents unscrewing of the closure lid 10, 110 and 10 ', 110' from the container neck. Return to normal output values of pressure or temperature in the container interior, enters the rotation 19, 119 and 19 ', 119' under the action of the compression spring 44, 144 and 44 ', 144' back to its original position, so that the Closing lid can be unscrewed through the non-rotatable connection of handle element and closure element again.
