Filter element, a filter set, and a filter device
A filter element for a motor vehicle for filtering a fluid has engaging and/or receiving elements that are designed to be connected to an adapter ring. The engaging and/or receiving elements have several hooks for engaging recesses of the adapter ring. and are arranged uniformly spaced in a circumferential direction about an central axis of the filter element. A filter set includes the filter element and the adapter ring, wherein the adapter ring deactivates a locking device of a first housing part that receives the filter element.
1. A filter set for a motor vehicle, the filter set comprising:
an adapter ring;
a filter element including:
a filter medium;
an end disk secured to the filter medium;
engaging or receiving elements secured to said filter element, said engaging and/or receiving elements comprise a plurality of hooks adapted to detachably engage into recesses of the adapter ring;
wherein the hooks are formed on the radially outer rim of the end disk and extend therefrom axially outwardly away from the filter medium; and
wherein the adapter ring is a separate component from the filter element, the adapter ring removably received over a radial exterior of the filter element and removably held in engagement with the engaging and/or receiving elements by the force of gravity;
wherein the adapter ring is adapted to deactivate a locking device of a first housing part that receives the filter element;
wherein the adapter ring is an annular ring element having an upper annular end face having the recesses adapted to receive the plurality of hooks of the filter element;
wherein the annular ring element on its radially outer side includes a plurality tabs protruding radially outwardly from the ring element, the tabs configured for engaging into matching recesses in a second housing part when the adapter ring is installed into the second housing part.
2. The filter set according to claim 1 , wherein
the engaging and/or receiving elements are arranged uniformly spaced in a circumferential direction about a central axis of the filter element.
3. The filter set according to claim 1 , wherein
the hooks are L-shaped hooks comprising:
a first leg having a first send secured onto the radially outer rim of the end disk and then extending in an axial direction outwardly away from the filter element to an opposing second end;
a second leg having an first end secured to the opposing second end of the first leg, the second leg extending in a radial direction outwardly away from the filter element and first leg.
4. A filter device for a motor vehicle, the filter device comprising:
a filter set comprising a filter element received in the first housing part, the filter element comprising:
a filter medium;
an end disk secured to the filter medium;
engaging or receiving elements secured to said filter element, said engaging and/or receiving elements adapted to be detachably connected to an adapter ring;
wherein the engaging and/or receiving elements comprise a plurality of hooks adapted to detachably engage into recesses of an adapter ring removably received over a radial exterior of the filter medium; and
wherein the hooks are formed on the radially outer rim of the end disk and extend thereform axially outwardly away from the filter medium;
wherein the adapter ring is received over a radial exterior of the filter element;
a first housing part having a locking device;
a second housing part that receives the filter element and is screw-mounted to the first housing part;
wherein the second housing part has a rim that is facing the and said adapter ring includes means to supplement a surface of said rim; and
wherein the locking device comprises a radially spring-pretensioned plunger adapted to slide along said supplemented surface of said second housing part and said locking device is deactivated by said adapter ring and said supplemented surface.
