Embodiment Construction

[0081] figure 1 A schematic cross-sectional view of a compressed air filter 1 according to a first preferred embodiment of the invention is shown. from figure 1 As can be seen in the figure, the compressed air filter 1 has a multi-part filter housing 2 consisting of a housing head 3 and a housing cover 4 which can be fixedly connected to the housing head. The housing head 3 has an inflow or outflow line 9 and an outflow or inflow line 10 for the compressed air to be cleaned or cleaned, as well as corresponding connections.

[0082] The compressed air filter 1 also includes a filter element 5 which can be inserted into the filter housing 2, which consists of an element base 6, an element head 7 and a filter medium 8 and which according to the present embodiment is preferably removed from the The rib 15 is designed rotationally symmetrically with respect to the central axis 46 . filter media according to figure 1 For example, it is coiled or folded in the shape of a hollow c...

Abstract

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).

Description

technical field [0001] The invention relates to a filter element and a compressed air filter for separating foreign bodies from a compressed air stream. [0002] Although the invention can be used in any filter system, the invention and the problem underlying the invention are explained in detail with reference to a compressed air filter. However, the concept of the invention can be applied, for example, to liquid separators or the like. Background technique [0003] Conventional compressed air filters generally consist of a two-part housing with a housing head and a housing cover, which are either screwed to one another or connected to one another by means of union nuts or bayonet connections. The housing head usually has inflow and outflow ducts on diametrically opposite sides. The inflow line opens either centrally into a hollow barrel-shaped replaceable filter element which is inserted or screwed into the housing head in a sealed manner or into an annular space between...
