The invention provides a filter assembly (10;100;300;400) for use in a cleaning appliance having a first filter portion (14) and a deformable rim (12;112;312;412), the first filter portion being surrounded by the deformable rim. The first filter portion (14) consists of a non-woven medium. The filter assembly (10;100;300;400) further comprises a second filter portion (16) located downstream of the first filter portion (14). The first filter portion (14) and the second filter portion (16) are held directly adjacent one another by means of the deformable rim (12;112;312;412). The filter assembly (10;100;300;400) further comprises a third filter portion (18) located upstream of the first filter portion (14) and consisting of a mesh material. The first filter portion (14) and the third filter portion (18) are held directly adjacent one another by means of the deformable rim. The filter assembly (10;100;300;400) has a tab (28) located on a surface thereof, to facilitate removal of the filter assembly (10;100;300;400) from a filter housing or a vacuum cleaner.

A filter assembly (10) for a vehicle heating or air conditioning system comprises a filter unit (22) which is cuboidal in the delivery condition. This filter unit (22) is inserted into a filter holding housing (24) and, in the process, is compressed to give a different cross section, which preferably has a trapezoidal shape.

The present invention relates to a filter element and a filter, wherein the filter element (2) comprises a cylindrical filter paper (8), as well as an annular upper ring (6) and an annular lower ring (7) connected to two ends of the cylindrical filter paper; gaps (C) are respectively formed, at least in positions on the outer peripheral surfaces of the annular upper ring (6) and annular lower ring (7), wherein each position is corresponding to an approximately central portion of each of the folds of the cylindrical filter paper (8). The filter element (2) can be pulled off in case of being cleaned, so that distances between the folds of the cylindrical filter paper (8) will be expanded, for the convenience of clearing dust off the cylindrical filter paper.
摘要:
Die vorliegende Erfindung betrifft ein Filter, wobei der Filter ein Gitter aufweist, welches in einem Fluidstrom angeordnet ist, wobei sich das Gitter beim Durchströmen des Fluidstromes in Strömungsrichtung von einer Grundform in eine Strömungsform reversibel verformt und beim Zurückformen von der Strömungsform in die Grundform gegebenenfalls vorhandene Schmutzpartikel abwirft.

Die Erfindung bezieht sich auf eine flexible Filteranordnung (1), bei welchen flexibles Filtermaterial (3) von einem starren, aber gasdurchlässigen Rahmen (2) getragen und durch Gasimpulse bewegt und dadurch gereinigt wird, wobei in das Innere der Filteranordnung ein Injektor (4) für Spülgas reicht und ein den Injektor im Abstand umgebendes Gasleitrohr (5) zum Ansaugen von Prozeßluft vorgesehen ist. Am unteren Ende der Filteranordnung kann eine Umlenkvorrichtung (6) vorgesehen sein, die zentrisch unter der Austrittsöffnung des Injektors angeordnet ein Umlenken des austretenden Spülgases und der durch das Gasleitrohr geführten und beschleunigten Prozeßluft auf die Innenseite des Filtermediums bewirkt.
摘要:
The invention relates to a round filter cartridge which has elastic end plates (34) terminating the front surfaces of a filtering medium (13). A support tube (27) has elastic areas formed by slits (29) at its ends, said areas being engaged in a positive fit with the elastic end plates (34). This connection gives when sealing surfaces (39) are mounted on corresponding connection pieces in the filter housing, so an additional seal is not necessary. The integration of the support tube (27) in the filter cartridge facilitates the mounting process in the housing. The cartridge itself can remain free of metal, which makes it easy to dispose of.
