Abstract
A filter device has a filter housing (1), in which a replaceable filter element (7) is accommodated. The filter housing has a cover part (2), wherein the element material (9) of the filter element (7) extends between two end caps (13, 14) of the filter element. The filter housing (1) is formed as an outlet pipe (3). The element material and the outlet pipe extend between both end caps (13, 14).
Claims15
A filter device, comprising:
- a filter housing having a cover part and being an outlet pipe with first and second axial ends;
- a replaceable filter element being accommodated in the cover part and having an element material extending between first and second end caps of the replaceable filter element, the outlet pipe only extending between the first and second end caps as well as the element material;
- first and second slot-shaped annular guides in the first and second end caps, respectively, receiving the first and second axial ends, respectively, of the outlet pipe, the first and second slot-shaped annular guides at least partially contacting wall parts on inner and outer circumferences of the outlet pipe;
- and
- a support tube extending on an outside of the element material between the first and second end caps,
- wherein:
- the second end cap has, on a top face thereof, a flat contact surface which is radially delimited on an outside by a peripheral rim projecting axially upwards;
- and
- the peripheral rim has on an inside a latching notch, to which a latching lug of the support tube is configured to be latched, to axially secure the support tube to the second end cap.
A filter device, comprising:
- a filter housing having a cover part and being an outlet pipe with first and second axial ends;
- a replaceable filter element being accommodated in the cover part and having an element material extending between first and second end caps of the replaceable filter element, the outlet pipe only extending between the first and second end caps as well as the element material;
- first and second slot-shaped annular guides in the first and second end caps, respectively, receiving the first and second axial ends, respectively, of the outlet pipe, the first and second slot-shaped annular guides at least partially contacting wall parts on inner and outer circumferences of the outlet pipe;
- and
- a support tube extending on an outside of the element material between the first and second end caps,
- wherein:
- the first end cap has a wall part projecting coaxially downward from a bottom of the first end cap, the wall part defining an enclosure for an upper end of the element material and an upper end of the support tube;
- a latching notch is defined on the wall part for latching the support tube to the first end cap;
- and
- a latching lug is defined on the support tube for latching the support tube to the first end cap.
