Such compressor units are z. B. with or as part of devices for sealing and inflating inflatable objects, in particular for sealing and inflation of motor vehicle tires needed (breakdown sets).

Die DE 44 29 097 AI zeigt eine solche Kompressoreinheit bzw. einen Kolbenverdichter mit einem im Stand der Technik üblichen Auslassventil, welches gleichzeitig das einzige „Überdruckventil" für den Innenraum des Kompressors ist. Ein solches Auslassventil besteht aus einer federbelasteten Scheibe, welche eine Auslassbohrung des Compressed gas source further comprise a sealant container for a fillable in the inflatable article automatic sealing means, a valve and distributor unit for sealant and compressed gas and are provided with an attachable to the compressed gas source inlet conduit and connectable to the inflatable object outlet.

Kompressionsraum/Druckraum zu verhindern. Dies erhöht insgesamt die Baugröße von Vorrichtungen zum Abdichten und Aufpumpen aufblasbarer Gegenstände. Ein Compression space / pressure chamber to prevent. This increases the overall size of devices for sealing and inflating inflatable objects. One
vergrößerter Bauraum steht aber dem Entwicklungstrend entgegen, solche Vorrichtungen und insbesondere deren Kompressoren möglichst platzsparend zu gestalten. However, increased space is contrary to the development trend to make such devices and in particular their compressors as space-saving.
Handelsübliche Pannensets zur Reifenabdichtung, die über einen Kleinkompressor verfügen, mit dessen Hilfe Reifen aufgepumpt werden können, nutzen zur Begrenzung des Maximaldruckes in der Regel also entweder das Auslassventil im Kompressionsraum in Verbindung mit einem entsprechend ausgelegten Totraum oder aber ein Ventil in der nachfolgenden Verteilereinheit, welches somit zwischen Auslassventil und Reifenventil bzw. zwischen Kompressor und Manometer angeordnet ist. Commercially available breakdown kits for tire sealing, which have a small compressor, with the help of tires can be used to limit the maximum pressure usually either the exhaust valve in the compression chamber in conjunction with a suitably designed dead space or a valve in the subsequent distribution unit, which is thus arranged between exhaust valve and tire valve or between compressor and pressure gauge.
Die Anordnung eines Überdruckventils zwischen Verteilereinheit und Auslassventil kann dazu führen, dass beim Pumpen von Dichtmittel Druckzustände entstehen können, die dazu führen, dass es zu einem unerwünschten Dichtmittelrückfluß kommt, der den Kompressor unbrauchbar macht. Andererseits verhindert ein Rückschlagventil in der nachfolgenden Verteilereinheit zwischen Auslassventil und Reifenventil, dass bei abgeschaltetem Kompressor mit dem integrierten Manometer der bestehende Druck messbar bleibt. Dementsprechend löst ein zusätzliches Rückschlagventil zwischen Kompressor und Manometer das Problem auch nicht zufriedenstellend. Für die Erfindung bestand daher die Aufgabe ein Überdruckventil bereitzustellen, welches die Begrenzung des Maximaldrucks im Kompressionsraum bei gleichzeitiger Vermeidung von Dichtmittelrückfiuß gewährleistet und damit Gebrauchsdauer und Zuverlässigkeit des Kompressors erhöht. Gelöst wird diese Aufgabe durch die Merkmale des Hauptanspruchs. Weitere vorteilhafte Ausbildungen sind in den Unteransprüchen offenbart. Dabei weist der Zylinderkopf ein parallel zum Auslassventil angeordnetes separates Überdruckventil für den Kompressionsraum auf. Damit erfolgt die Absicherung/Einstellung des Maximaldrucks schon im The arrangement of a pressure relief valve between the distributor unit and the outlet valve can lead to pressure conditions during the pumping of the sealant, which lead to undesirable reverse flow of the sealant, which renders the compressor unusable. On the other hand, prevents a check valve in the subsequent distribution unit between exhaust valve and tire valve that with the compressor off with the integrated pressure gauge, the existing pressure remains measurable. Accordingly, an additional check valve between compressor and pressure gauge does not solve the problem satisfactorily. For the invention, therefore, the object was to provide a pressure relief valve, which ensures the limitation of the maximum pressure in the compression chamber while avoiding Dichtmittelrückfiuß and thus increases the useful life and reliability of the compressor. This object is achieved by the features of the main claim. Further advantageous embodiments are disclosed in the subclaims. In this case, the cylinder head on a parallel to the exhaust valve arranged separate pressure relief valve for the compression chamber. Thus, the hedge / setting of the maximum pressure is already in
Kompressionsraum (Zylinder). Dadurch muss die nachfolgende Konstruktion nicht mehr den Maximaldrücken standhalten, was zu einer Material- & Kostenersparnis führt, da diese nachgelagerten Teile nicht so aufwendig konstruiert werden müssen. Der Rückfluss von Dichtmittel bei Pumpsystemen ist mit einer solchen Kompressoreinheit ausgeschlossen. Das Auslassventil trennt nämlich das Fördersystem vom Überdruckventil. Dies ermöglicht eine Dichtmitte lpumplösung, die auch in Verbindung mit niedrigen Maximaldrücken und der Verwendung von hochviskosem Dichtmittel funktioniert. Als niedrige Maximaldrücke werden solche bezeichnet, die erheblich unter den heute üblichen Drücken von 600 bis 800 kPa liegen.  Compression space (cylinder). As a result, the subsequent design no longer has to withstand the maximum pressures, resulting in a material and cost savings, since these downstream parts do not need to be designed so expensive. The reflux of sealant in pump systems is excluded with such a compressor unit. The outlet valve separates the conveyor system from the pressure relief valve. This enables a sealant solution that also works in conjunction with low maximum pressures and the use of highly viscous sealant. Low maximum pressures are those which are considerably lower than the usual pressures of 600 to 800 kPa.
Eine vorteilhafte Weiterbildung besteht darin, dass das Überdruckventil einen An advantageous development is that the pressure relief valve a
Überdruckventilkörper und/oder einen Überdruckventilsitz aus elastomerem Material, vorzugsweise aus Gummi, aufweist. Bei einem Überdruckventilkörper aus elastomerem Material kann ein sehr schnell arbeitendes Ventil geringer Masse bereitgestellt werden, das sogar so ausgelegt werden kann, dass die eigene Elastizität genügend Federkraft bereitstellt, um den Überdruckventilkörper bis zum Erreichen eines bestimmtem Drucks auf dem Überdruckventilsitz zu fixieren. Bei einem Überdruckventilsitz aus elastomerem Material, in den sich der Überdruckventilkörper eindrücken kann, entsteht auf einfache Weise zusätzliche Elastizität / Federkraft. Relief valve body and / or a pressure relief valve seat made of elastomeric material, preferably made of rubber. In a relief valve body made of elastomeric material, a very fast working valve of low mass can be provided, which can even be designed so that its own elasticity provides sufficient spring force to fix the pressure relief valve body until a certain pressure on the pressure relief valve seat is reached. In a pressure relief valve seat made of elastomeric material, in which the pressure relief valve body can press, creates additional elasticity / spring force in a simple way.
Eine weitere vorteilhafte Ausbildung in diesem Sinne besteht darin, dass der A further advantageous embodiment in this sense is that the
Überdruckventilkörper federbelastet ist, bzw. zusätzlich zur eigenen Elastizität Relief valve body is spring loaded, or in addition to its own elasticity
federbelastet ist. Eine weitere vorteilhafte Ausbildung besteht darin, dass das Überdruckventil einen alsspring loaded. A further advantageous embodiment is that the pressure relief valve as a
Rückschlagventil mit einer federbelasteten Stahlkugel als Überdruckventilkörper aufweist. Dies ist eine besonders einfache und vielfach bewährte Ausführung, die als Zubehör leicht erworben werden kann. Die Stahlkugelventilkonstruktion ermöglicht den Einsatz auch für Zylinderköpfe aus Metall und lässt höhere Einsatztemperaturen zu. Eine weitere vorteilhafte Ausbildung besteht darin, dass die Vorspannung, also der „Sitzdruck" des Überdruckventilkörpers auf dem Überdruckventilsitz einstellbar ist. In einfachster Ausführung geschieht dies beispielsweise durch eine die Federkraft beeinflussende Einstellschraube. Eine weitere vorteilhafte Ausbildung besteht darin, dass die Überdruckventilöffnung einen Durchmesser zwischen 1 und 5 mm aufweist, vorzugsweise 1,5 bis 3 mm. Damit lässt sich auf einfache Weise die Auslegung auf Federwirkung und Durchlassmenge beim Öffnen beeinflussen. Besonders geeignet ist eine solche Kompressoreinheit für eine Vorrichtung zum Abdichten und Aufpumpen aufblasbarer Gegenstände, insbesondere zum Abdichten und Aufpumpen von Kraftfahrzeugreifen. Having check valve with a spring-loaded steel ball as a pressure relief valve body. This is a particularly simple and well proven design that can be easily purchased as an accessory. The steel ball valve construction also allows the use of metal cylinder heads and allows higher operating temperatures. A further advantageous embodiment consists in that the pretension, that is the "seat pressure" of the overpressure valve body, can be adjusted on the overpressure valve seat In the simplest embodiment, this is done, for example, by an adjustment screw which influences the spring force 1 and 5 mm, preferably 1.5 to 3 mm, which makes it easy to influence the design of the spring effect and the amount of opening during the opening process Inflating motor vehicle tires.
