Air filter, Filter Element and Filter Housing of an Air Filter

摘要

An air filter (10) includes an openable filter housing (12) and a filter element (18). The filter housing (12) includes an inlet (26) and an outlet. A filter element (18) with a filter medium (46) is disposed replaceably in the filter housing separating the inlet (26) from the outlet (22). The filter element (18) features on an exterior side facing away from the element interior space (52) on an axial front face relative to the element axis (32) at least one supporting element (58) having at least one supporting lateral surface (60, 61) with at least one cylindrical portion and/or at least one portion with a variable cross-section in the direction of a main axis. The supporting element (58) is supported at least transversely in relation to the element axis (32) with the at least one supporting lateral surface (60, 61) against at least one corresponding support portion (42) on the side of the filter housing (12).

1. An air filter, comprising:
an openable filter housing including
a housing pot;a housing cover sealingly mount onto and removable from the housing pot;at least one air inlet though which airflow to be cleaned enters the filter housing;at least one air outlet through which cleaned air exits the filter housing;wherein the filter housing has a housing axis (32); a filter element removeably and replaceably installed into the element interior space of the filter housing, the filter element including
a filter medium radially surrounding and defining an element interior space within the filter element;wherein the filter element engages with an interior of the filter housing separating the at least one inlet from the at least one outlet;wherein the filter element has an element axis (32; 132; 232);at least one supporting element (58; 158; 258) is arranged at and secured onto a first end on an exterior of an axial end face of the filter element, the exterior axial end face facing away from the element interior space, the at least one supporting element including
at least one axially extending supporting lateral surface (60, 61; 160, 161; 260, 261) arranged on the at least one supporting element;wherein the at least one supporting lateral surface has at least one of: at least one cylindrical portion arranged radially relative to the element axis (32; 132; 232) or at least one portion with a cross section that varies along a direction of the element axis (32; 132; 232);wherein the at least one supporting element is mounted on and supported at least transversely in relation to the element axis (321; 132; 232) on at least one corresponding support member (42; 142) secured onto a side of the filter housing (12; 112; 212).
