Filter element with retaining surfaces, filter with a filter element and filter housing of a filter

A filter element (10) configured for installation into an air filter housing (11), comprising:

• an filter body (16) of a filter medium (18), the filter body having
• an oncoming flow side (28) where fluid to be filtered enters the filter element;
• and
• an outgoing flow side (30) where fluid to be filtered exits the filter element and defining an element axis (14) extending through the filter element from the oncoming flow side (28) to the outgoing flow side (30),
• wherein, as used herein, axial is a direction parallel to the element axis and radial is a direction transverse to the element axis;
• the filter body comprising a plurality of radially outer longitudinal surfaces (24) of the filter body (16), the plurality of radially outer longitudinal surfaces extending axially from the oncoming flow side (28) of the filter body (16) to the outgoing flow side (30) of the filter body (16);
• wherein the filter element comprises:
• a first end disk (32) disposed on and connected to a first radially outer longitudinal surface of the plurality of radially outer longitudinal surfaces of the filter body(16), the first end disk arranged between the oncoming flow side (28) and the outgoing flow side (30);
• wherein the plurality of radially outer longitudinal surfaces of the filter body (16) include a pair of radially opposing outer longitudinal surfaces consisting of:
• a radially opposing outer longitudinal surface arranged at a first edge of the first radially outer longitudinal surface of the filter body (16);
• and
• a second opposing outer longitudinal surface of the filter body (16) arranged at an opposite second edge of the first radially outer longitudinal surface of the filter body (16);
• at least one longitudinal retaining configuration (38) connected to and extending axially across a radially outer surface of the first end disk, having:
• at least one longitudinal retaining surface (40) extending axially across a radially outer surface of the first end disk,
• wherein the at least one longitudinal retaining surface (40) is adapted to contact a corresponding longitudinal mating surface of the filter housing (11) when in an installed state in the filter housing, the at least one longitudinal retaining surface (40) supporting the filter element (10) in position axially;
• and
• a traverse retaining configuration (46) connected to the first end disk (32) and spaced axially away from the at least one longitudinal retaining configuration (38), the traverse retaining configuration (46) including:
• at least one transverse retaining fork (250), each have a first leg (52) and a second leg (52), the first and second legs spaced apart in a radial direction transverse to the element axis forming a gap therebetween, the first leg (52) and the second leg (52) projecting radially outwardly from the first end disk,
• wherein the at least one transverse retaining fork is configured to receive and engage a transverse retaining receptacle (54) of the filter housing into the gap between the first and second legs,
• wherein in the installed state, the at least one retaining fork (250) fixes a position of the filter element (10) in the housing (11) in a direction traverse to the element axis (14).
