A ring filter element, e.g., for a liquid filter device, is disclosed. The ring filter element includes an upper end disc, a lower end disc, and a filter material arranged in between the upper end disc and the lower end disc. A pin eccentrically arranged on the lower end disc that projects in an axial direction is provided for closing off a drainage channel. At least one support contour is disposed on the lower end disc adjacently to the pin. The at least one support contour projects from the lower end disc in the axial direction for supporting on a filter housing.

Ring filter element and liquid filter device

A filter device is disclosed. The filter device includes a coalesce and a final separator arranged one after another in a flow direction. The final separator includes final separator material and is arranged radially within the coalesce. The coalesce is configured hollow-cylindrical and includes a coalescer material and an external support structure with an upper coalescer ring and a lower coalescer ring that are connected with one another via axial coalescer ribs. A positioning element is provided on the final separator. A positioning opening is provided in a region of the at least one lower coalescer ring. The positioning opening is configured in a complementary manner to the positioning element and the final separator engages into the positioning opening in a mounted state with the positioning element and thereby aligns the final separator relative to the coalesce.

Filter device

A liquid filter device may include a filter housing and a ring filter element arranged in the filter housing. The filter housing may include a filter housing cover and a filter housing pot connectable tightly therewith via a housing seal. A discharge channel, a central clean channel, and a vent channel may be disposed in the filter housing pot. The ring filter element may include an upper end plate, a lower end plate, and a pleated star. When the liquid filter device is in an operating state, a pin arranged on the lower end plate may be disposed in and seal the discharge channel via a first seal, a second seal arranged on the lower end plate may be disposed against a surface of the clean channel, and a third seal arranged on the upper end plate may be disposed against a surface of the vent channel.

Liquid filter device

A filter arrangement may include a filter housing and a ring filter element arranged in the filter housing. The ring filter element may include an upper end plate, a lower end plate, and a filter material arranged therebetween. An axially projecting pin may be disposed on the lower end plate and may engage into a channel on a filter housing side. The filter arrangement may also include a tubular dome which may engage into an interior of the ring filter element. The tubular dome may have a guide contour. The guide contour may cooperate with a guide element arranged on the ring filter element and may have an axial groove. The guide contour may be configured as at least one of a circular ramp and a chamfered cannula. On the upper end plate, an axial stop may project into the interior of the ring filter element.

Filter arrangement

Filter

A filter device may include a filter housing, a ring filter element arranged within the filter housing, a tubular dome engaging in an interior of the ring filter element, and a valve arranged in a clean channel. The ring filter element may include a lower end disc and a pin. The ring filter element may engage a first channel via the pin. The tubular dome may have a guiding contour which may interact with a guiding element of the ring filter element. The guiding contour may include an axial groove. The pin may be introducible into the first channel when the guiding element enters the axial groove. The guiding element and the valve may be structured and arranged such that the guiding element interacts with a valve body of the valve and transfers the valve body into an opening position when the guiding element is slid into the axial groove.

A filter element of at least one of a vehicle and an internal combustion engine may include an annular filter body, an inner frame supporting the filter body, an upper end plate and a lower end plate arranged axially on the filter body, a pin eccentrically arranged on the lower end plate, a plurality of centring elements, and a positioning web. The annular filter body may surround a cylindrical inner space. The plurality of centring elements may be arranged distributed in a circumferential direction of the filter body around the first plate opening, protrude axially into the inner space, and respectively have a chamfer. The positioning web may be arranged on at least one of the upper end plate and the inner frame in the circumferential direction between two centring elements of the plurality of centring elements and extend parallel to the two centring elements.
