Embodiment Construction

[0056] Components that are the same or of the same type are provided with the same reference symbols in the figures. The figures show examples only and are not to be construed as limiting.

[0057] figure 1 A cross-sectional view of a filter system 100 according to one embodiment of the invention is shown. A filter system 100 for filtering fluids having an inlet 102 on the front side and an outlet 104 comprises a filter element 10, a filter housing 108, a housing for coupling the filter system 100 to the outside of the filter system Coupling device 30 at part 32 (in image 3 ), and a seal holder 16 with a seal 18 for sealing the filter system at the receptacle 32 . In this case, the coupling device 30 provides a plurality of coupling elements 36 which, by means of a push-rotation movement, can be introduced at least partially in the axial direction L into a coupling contour 34 arranged in the receptacle 32 in order thereby to The filter system 100 is held and locked in the...

Abstract

The invention relates to a filter system (100) for filtering fluids with a front-side inlet (102) and outlet (104), comprising at least one filter element (10), a filter housing (108), A coupling device (30) for coupling a filter system (100) to a receptacle (32) external to the filter system and comprising a seal holder (16) with a seal (18) which The piece (18) is used to seal the filter system at the receiver (32). In this case, the coupling device ( 30 ) provides one or more coupling elements ( 36 ), which can be inserted into the mountings arranged on the receiving part at least partially in the axial direction (L) by means of a push-rotation movement. ( 32 ) in the coupling contour ( 34 ) in order thereby to hold and lock the filter system ( 100 ) in the end position ( 38 ) in the receptacle ( 32 ). The invention furthermore relates to the combination of a filter system ( 100 ) and a holder ( 32 ) according to one of the preceding claims.

Description

technical field [0001] The invention relates to a filter system with a coupling device for filtering fluids, in particular for use as a fuel filter for an internal combustion engine. Background technique [0002] It is known that one of the challenges in the construction of replaceable filter systems is to achieve a secure mounting and sealing on the receptacle on which the filter system is mounted. The mechanical interface must be designed as simply as possible and still be solid and reliable. The filter system must be able to be replaced repeatedly as simply, quickly and without problems as possible. Furthermore, it applies that a large number of installations are covered with a similar solution in order to be able to realize a cost-effective filter system. [0003] Fuel filters typically use disposable filter elements that are replaced after predetermined intervals of filter use. Disposable elements are traditionally secured at the filter construction base by holding o...
