Eine bevorzugte Ausführungsform sieht vor, dass die Ringkammer mit einer Kontrolfflüssigkeit gefüllt ist und mit einem Kontrollbehälter kommuniziert. Damit wird der Vorteil einer ständigen Kontrolle der Dichtwirkung erreicht. Bevorzugt weist der Kontroübehälter eine Flüssigkeitsstandanzeige auf, durch welche der Flüssigkeitsstand laufend kontrolliert werden kann. Sinkt beispielsweise der Stand der Kontroll- flüssigkeif im Kontrolibehälter ab, läuft Kontrollflüssigkeit aus der Ringkammer aus, d. h. das innere (dem Bootsinπeren zugewandte) Dichtelement ist undicht, sodass die Kontrollflüssigkeit in das Bootsinnere ausströmt. Andererseits kann der Stand der Kontrollflüssigkeit im Kontrollbehälter ansteigen - in diesem Falle dringt Seewasser in die Ringkammer ein, d. h. das äußere, seewasserseitige Dichtelement ist undicht, während das innere Dichtelement noch intakt ist. Schließlich ist der Fall möglich, dass beide, das innere und das äußere Dichteiemenf undicht werden, auch dann ergibt sich eine Änderung des Kontrollpegels, d. h. eine Warnung für einen Wasserein-A preferred embodiment provides that the annular chamber is filled with a control liquid and communicates with a control container. Thus, the advantage of a permanent control of the sealing effect is achieved. Preferably, the Kontroübehälter on a liquid level indicator, by which the liquid level can be controlled continuously. If, for example, the level of the control fluid in the control tank drops, control fluid escapes from the annular chamber, i. H. the inner (the Bootsinπeren facing) sealing element is leaking, so that the control fluid flows into the boat interior. On the other hand, the level of the control liquid in the control tank may increase - in this case, seawater enters the annular chamber, i. H. the outer, seawater-side sealing element is leaking, while the inner sealing element is still intact. Finally, the case is possible that both the inner and outer density belts are leaking, even then there is a change in the control level, i. H. a warning for a water intake

Damit ist auch das Volumen der Rsπgkammer zur Aufnahme der Kontrollflüssigkeit definiert.Peripheral area of the trunk opening. Thus, the Dichtefemente can be clamped with their peripheral beads on both sides, so that there is a leak-tight seal. This also defines the volume of the Rsπgkammer for receiving the control liquid.
Nach einer weiteren bevorzugten Ausführungsform ist die Rumpföffnung in einem Rumpfzwischenstück, im folgenden auch kurz Zwischenstück genannt, angeordnet, welches in den Bootsrumpf einsetzbar ist. Daraus ergibt sich der Vorteil, dass die Ringkammer, die flexiblen Dichtelemente und die Klemmvorrichtungen mit dem Zwischenstück ais Baueinheit vormontiert werden können, welche dann in die eigentliche Rumpföffnung eingesetzt wird.According to a further preferred embodiment, the hull opening in a fuselage intermediate piece, hereinafter also referred to as intermediate piece, arranged, which can be inserted into the hull. This results in the advantage that the annular chamber, the flexible sealing elements and the clamping devices can be pre-assembled with the intermediate piece as a unit, which is then inserted into the actual hull opening.
Nach einer weiteren bevorzugten Ausführungsform kann das Rumpfzwischenstück als Crashtei! ausgebildet werden, und zwar vorzugsweise in Sandwichbauweise. Da das Zwischenstück - aufgrund der flexibieπ Dichtelemente - keine Reaktionskräfte aus dem Schraubenschub aufnimmt, kann es leicht und verformbar ausgebil-According to another preferred embodiment, the fuselage interface as Crashtei! be formed, preferably in sandwich construction. Since the intermediate piece - due to the flexible sealing elements - does not absorb any reaction forces from the screw thrust, it can be easily and deformably formed.

Fig. 2 zeigt die Dichtungsanordnung 1 in Verbindung mit einem teilweise dargestellten Bootsantrieb 8 und dem Zwischenstück 2, welches hier mit der inneren Stahlplatte 2a und einer äußeren (seewasserseitigen) Stahlplatte 2b dargestellt ist. Der Bootsantrieb 8 umfasst eine schwenkbare, über ein nicht näher erläutertes Getriebe antreibbare Steuereinrichtung 9, welche ein Gehäuse 9a zur Aufnahme einer Antriebswelle 10 für einen nicht dargestellten Propeller (auch Schraube genannt) aufweist. Die Steuereinrichtung 9 ist gegenüber einem rumpfseitig abgestützten Lager 11 schwenkbar um die Hochachse z gelagert und in beiden axialen Richtungen fixiert. Am Lager 11 ist die innere Kiemmvorrichtung 3 befestigt, während die äußere Klemmvorrichtung 4 mit dem Zwischenstück 2 verbunden ist. Der gesamte Bootsan- \s Lager 11 , i« ti und dem Gewicht des Bootsaπtriebes 8 direkt in den Rumpf eingeleitet werden. DasFig. 2 shows the seal assembly 1 in conjunction with a partially illustrated boat drive 8 and the intermediate piece 2, which is shown here with the inner steel plate 2a and an outer (seawater side) steel plate 2b. The boat drive 8 comprises a pivotable control device 9, which can be driven via an unspecified transmission and which has a housing 9a for receiving a drive shaft 10 for a propeller (also called a screw), not shown. The control device 9 is mounted pivotably about the vertical axis z relative to a support 11 supported on the fuselage side and fixed in both axial directions. At the bearing 11, the inner Kiemmvorrichtung 3 is fixed, while the outer clamping device 4 is connected to the intermediate piece 2. The entire boat Bearing 11, i «ti and the weight of the boat drive 8 are introduced directly into the hull. The
elastischen Aufhängung führt der Bootsaπtrieb 8, insbesondere in senkrechter Richtung (z-Richtung) Schwingungen aus, d. h. es findet eine Relativbewegung zwischen der inneren Klemmvorrichtung 3 und der äußeren Klemmvorrichtung 4 statt, welche durch die flexiblen Dichtelemente 5, 6 zugelassen wird.elastic suspension leads the Bootsaπtrieb 8, in particular in the vertical direction (z-direction) oscillations, d. H. There is a relative movement between the inner clamping device 3 and the outer clamping device 4 instead, which is allowed by the flexible sealing elements 5, 6.
Die Ringkammer 7, weiche mit einer KontroHflüssigkeit gefüllt ist, kommuniziert mit einem Kontrolibehälter 11 , welcher eine nicht dargestellte Hüssigkeitsstandan- zeige aufweist. In der äußeren Klemmvorrichtung 4 sind eine Quer- und eine Längsbohrung 12a, 12b angeordnet, über welche die Ringkammer 7 an eine nicht dargestellte flexible Verbindungsleitung zum Kontrallbehäiter 11 angeschlossen werden kann. Mit diesem System ist eine FunktionskontroHe der Dichtelemente 5, 6 möglich. Bei einer Veränderung des Flüssigkeitsstandes im Kontrollbehälter 11 liegt in der Regel eine Funktionsstörung der Dichtung vor. Steigt der Flüssigkeitspege! im Kontrollbehälter, ist das seewasserseitige Dichtelement 6 defekt, Seewasser strömt in die Ringkammer 7 und von dort in den KontroIlbehäSter 11. Fällt der Fiüssigkeitspege! im Kontroflbehälter 11 , ist das innere Dichtelement 5 defekt, und die Kontrollflüssigkeit tritt aus der Ringkammer 7 in das Bootsinnere aus. Bei sinkendem Flüssigkeitspegel im Kontrolibehälter 11 kann ferner der FaI! vorliegen, dass beide Dichtelemente 5, 6 undicht sind und somit Seewasser in den Bootsinnenraum strömt. Somit ist durch die mit dem Kontrolibehälter 11 über die Kontroilflüssigkeit kommunizierende Ringkammer 7 eine wirksame und ständige Kontrolle darüber gegeben, ob die Dichtung intakt ist oder ob eine Störung in Form einer Undichtigkeit vorliegt.The annular chamber 7, which is filled with a KontroHflüssigkeit communicates with a Kontrolbehälter 11, which has a Hüssigkeitsstandan- display, not shown. In the outer clamping device 4, a transverse and a longitudinal bore 12a, 12b are arranged, via which the annular chamber 7 can be connected to a flexible connecting line, not shown, to the Kontrallbehäiter 11. With this system, a FunktionskontroHe the sealing elements 5, 6 is possible. In a change in the liquid level in the control vessel 11 is usually a malfunction of the seal. Rises the liquid spege! in the control tank, the seawater side sealing element 6 is defective, seawater flows into the annular chamber 7 and from there into the KontroIlbehäSter 11. Falls the Fiüssigkeitspege! in the Kontroflbehälter 11, the inner sealing element 5 is defective, and the control liquid exits from the annular chamber 7 in the boat interior. With decreasing liquid level in the Kontrolbehälter 11 may also FaI! be present that both sealing elements 5, 6 are leaking and thus seawater flows into the boat interior. Thus, the annular chamber 7 communicating with the control tank 11 via the control fluid provides effective and constant control as to whether the gasket is intact or whether there is a malfunction in the form of a leak.
Im dargestellten Ausführungsbeispiel ist lediglich eine Ringkammer 7 dargestellt, welche von zwei Dichtelementen 5, 8 eingeschlossen wird.
