Filter element and compressed air filter for separating foreign matter from a compressed air stream

摘要

The present invention provides a compressed air filter (1) and a filter element (5) for separating foreign matter from a compressed air stream, comprising an element base (6), an element top (7) with a neck section (13) that forms a first flow channel (9) and a collar section (14) that is designed at least in sections to surround the neck section (13) and that is connected to the neck section (13), thereby forming a second flow channel (10), and comprising a filter medium (8) that is connected to the element base (6) and to the element top (7) to form a gas stream path between the first flow channel (9) and the second flow channel (10) through the filter medium (8) in a sealing manner, wherein the collar section (14) comprises a support surface (16) that is provided on the outer periphery at least in sections and that narrows in the direction of the element base (6), said support surface accommodating an associated seal ring (22) such that a force acting on the seal ring (22) approximately axially from the direction of the element base (6) causes a radial expansion of the seal ring (22) along the support surface (16).
