Abstract
A filter device with a filter housing (2, 6), in which a replaceable filter element (4) is accommodated and which has a cover part (2). Element material (30) is delimited at the end by at least one end cap (32). This end cap (32) of the filter element (4) is placed on a fluid channel (58). A device (84) for transverse force support for the filter element (4) is provided between this one end cap (32) and the fluid channel (58). The device (84) for transverse force support supports the filter element (4) in relation to the fluid channel (58) engaging in the interior of the filter element (4) at least partially at the end.
Claims16
A filter device, comprising:
- a filter housing having a cover part;
- a replaceable filter element in being accommodated in the filter housing and having element material delimited at one end thereof by an end cap placed on a fluid channel;
- a transverse force support supporting the filter element and being provided between the end cap and the fluid channel, the transverse force support supporting the filter element in relation to the fluid channel and engaging in an interior of the filter element at least partially at the one end, the transverse force support including a sleeve having a turned-in rim at one end of the sleeve and a perimeter wall as part of a guide for the fluid channel at another end of the sleeve;
- and
- a bar-shaped annular flange formed at the outer circumference of the perimeter wall and engaging the end cap with a step-shaped recess.
A filter device, comprising:
- a filter housing having a cover part;
- a replaceable filter element in being accommodated in the filter housing and having element material delimited at one end thereof by an end cap placed on a fluid channel;
- a transverse force support supporting the filter element and being provided between the end cap and the fluid channel, the transverse force support supporting the filter element in relation to the fluid channel and engaging in an interior of the filter element at least partially at the one end;
- and
- guide ridges projecting from the end cap, the guide ridges having conically converging guide surfaces pointing in a direction of a receiving opening in engagement with the fluid channel.
