Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Flüssigkeitsfilter nach der Gattung des Hauptanspruchs. Es ist schon ein Flüssigkeitsfilter aus der
Aus der
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Flüssigkeitsfilter mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass das Flüssigkeitsfilter weniger Bauraum benötigt, indem die Aufnahme für das Druckregelventil in das Filtergehäuse hineinragt. Auf diese Weise wird die Aufnahme optimal in das Filtergehäuse integriert und beansprucht weder außerhalb noch innerhalb des Filtergehäuses zusätzlichen Bauraum.The liquid filter according to the invention with the characterizing features of the main claim has the advantage that the liquid filter requires less space by the receptacle for the pressure control valve protrudes into the filter housing. In this way, the recording is optimally integrated into the filter housing and claimed neither outside nor within the filter housing additional space.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Flüssigkeitsfilters möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim liquid filter are possible.
Sehr vorteilhaft ist, wenn das Druckregelventil von außen in die Aufnahme einsetzbar ist, da die Montage des Druckregelventils auf diese Weise unabhängig von dem Herstellungsprozess des Filtergehäuses erfolgen kann. Das Druckregelventil ist außerdem austauschbar, ohne das Filtergehäuse öffnen zu müssen.It is very advantageous if the pressure control valve can be inserted from the outside into the receptacle, since the assembly of the pressure control valve can be effected in this way independently of the production process of the filter housing. The pressure regulator is also interchangeable without having to open the filter housing.
Besonders vorteilhaft ist, wenn die Aufnahme derart ausgebildet ist, dass das Druckregelventil vollständig in der Aufnahme versenkbar ist, da das Druckregelventil auf diese Weise keinen Bauraum außerhalb des Flüssigkeitsfilters beansprucht.It is particularly advantageous if the receptacle is designed such that the pressure control valve is completely retractable in the receptacle, since the pressure control valve claimed in this way no space outside of the liquid filter.
Weiterhin vorteilhaft ist, wenn die Aufnahme eine von dem Druckregelventil gesteuerte Druckablassöffnung des Filtergehäuses aufweist. Auf diese Weise kann der im Inneren des Flüssigkeitsfilters herrschende Druck über die Druckablassöffnung und das Druckregelventil verringert werden.It is also advantageous if the receptacle has a pressure relief opening of the filter housing which is controlled by the pressure regulating valve. In this way, the pressure prevailing in the interior of the liquid filter pressure can be reduced via the pressure release opening and the pressure control valve.
Desweiteren vorteilhaft ist, wenn das Druckregelventil in die Aufnahme eingesteckt und in der Aufnahme mittels eines Sicherungsringes gehalten ist, da das Druckregelventil auf diese Weise besonders einfach und kostengünstig am Filtergehäuse montierbar ist.Furthermore, it is advantageous if the pressure regulating valve is inserted into the receptacle and held in the receptacle by means of a securing ring, since the pressure regulating valve can be mounted in this way in a particularly simple and cost-effective manner on the filter housing.
Außerdem vorteilhaft ist, wenn der Sicherungsring einen Anschluss zur elektrischen Erdung des Druckregelventils aufweist, da auf diese Weise elektrostatische Ladungen vom Druckregelventil ableitbar sind und keine Gefahr der Funkenbildung besteht.It is also advantageous if the retaining ring has a connection for electrical grounding of the pressure regulating valve, since in this way electrostatic charges can be derived from the pressure regulating valve and there is no risk of sparking.
Auch vorteilhaft ist, wenn die Aufnahme für das Druckregelventil an die Geometrie des Druckregelventils angepasst ist, da das Druckregelventil auf diese Weise gut gegenüber der Wandung der Aufnahme abdichtbar ist. Gemäß dem Ausführungsbeispiel ist an dem Ventilgehäuse des Druckregelventils zur Abdichtung ein mit der Wandung der Aufnahme zusammenwirkender Dichtring vorgesehen.It is also advantageous if the receptacle for the pressure regulating valve is adapted to the geometry of the pressure regulating valve, since the pressure regulating valve can be sealed well in this way with respect to the wall of the receptacle. According to the embodiment, a cooperating with the wall of the receptacle sealing ring is provided on the valve housing of the pressure regulating valve for sealing.
Weiter vorteilhaft ist, wenn das Druckregelventil einen Ventileinlass und einen Ventilauslass aufweist, wobei der Ventileinlass an einer der Aufnahme zugewandten Stirnseite und der Ventilauslass am Umfang des Ventilgehäuses vorgesehen ist. Die Anordnung des Ventilauslasses am Umfang hat den Vorteil, dass eine große Abströmöffnung erreicht wird.It is also advantageous if the pressure regulating valve has a valve inlet and a valve outlet, the valve inlet being provided on an end face facing the receptacle and the valve outlet being provided on the circumference of the valve housing. The arrangement of the valve outlet at the periphery has the advantage that a large discharge opening is achieved.
