Embodiment Construction

[0015] corresponds to figure 1 , the filter device 1 according to the invention has a filter housing pot 2 and a filter housing cover 3 connected thereto. In this case, the filter housing pot 2 is made of metal and has at least one through-opening 5 in the form of an escutcheon in the bottom region 4 . In the embodiment shown, the filter device 1 according to the invention has in the bottom region 4 two through holes 5 and 5'. Furthermore, the filter device 1 has a component 6 made of plastic in the form of at least one nozzle 7 for supplying or removing the filter device 1 . The component 6 made of plastic is here sealed relative to the filter housing pot 2 by means of an annular seal 8 , wherein the nozzle 7 protrudes through the through opening 5 in the bottom region of the filter housing pot 2 . In addition, component 6 has a heating device 9 . In this case, the heating device 9 can be embedded in the plastic of the component 6 or can also be fixedly connected to t...

Abstract

The invention relates to a filter device (1) having a filter housing vessel (2) and a filter housing cover (3) which can be connected thereto, wherein - the filter housing vessel (2) is formed from metal and, in a floor region (4), has at least one passage opening (5) formed in the manner of an aperture mask, - a component (6) formed from plastics material and having a heating device (9) and at least one fitting (7) for supply to, or removal from, the filter device (1) is provided, which component is sealed with respect to the filter housing vessel (2) and is penetrated by the at least one passage opening (5) in the floor region (4) of the filter housing vessel (2). In this way it is possible to provide in particular a crash-optimised filter device (1) in an inexpensive manner.

Description

technical field [0001] The invention relates to a filter device having a filter housing pot and a filter housing cover connected thereto. Background technique [0002] In order to be able to design the filter devices reliably, in particular also for crash situations, the filter housings of these filter devices are usually made of metal, whereby the filter device itself has a significantly increased stability. However, such metal filter housings have the disadvantage that all nozzles for the supply or removal of the filter device must be welded or welded and sealed at high cost, resulting in a non-negligible cost factor . Contents of the invention [0003] The problem addressed by the invention is therefore to provide an improved or at least an alternative embodiment of a filter device which is characterized on the one hand by a high crash stability and on the other hand by a relatively low manufacturing cost. cost. [0004] According to the invention, this problem is so...
