摘要： There is disclosed an axially folded tubular filter element for the filtration of fluids. The ends of the radially extending folds are in abutment at the internal folds with a support core and in abutment at the externally facing folds internally with an outer support grid. The support has a plurality of perforations. The ends of the tubular filter element are enclosed by a cap which encloses the ends of the tubular filter element in a sealing manner. The outside of the support core which supports the internally facing fold edges has a series of outwardly extending corrugated sections with rounded corrugated outwardly extending ridges, and the said perforations are located in the valleys of the corrugations. The corrugated structure extends in a longitudinal direction, is relatively flat and runs in a circumferential direction. A drainage pathway is also supplied along the outer surface of the support core.

摘要： A filter consisting of connected upper housing and lower housing parts and a hydrophobic flat filter disc for gas filtration sandwiched therebetween, intended in particular for an exchange between a container such as a liquid reservoir partially filled with liquid and the surrounding atmosphere. The upper housing part includes an integral channelled filter support having channels for communication into a gas inlet-outlet means of the said upper housing part. The lower housing part includes an integral, channelled filter support having channels for communication into a centrally disposed bore located at a right angle to the filter support and empties into the gas area of a liquid reservoir for instance. The filter support is constructed to prevent liquid from completely blocking the hydrophobic filter disc.The filter support of the lower housing forms a planar plane with an annular channel therein and a series of radially extending channels terminating at a centrally located bore. The channels having a controlled depth. The bore diameter is also controlled. The upper housing is dimensioned to provide a controlled distance for the filter from the filter support in the lower housing.

摘要： In a filter with fluid connections, an upper housing part (1) and a lower housing part (8) a flat filter blank (7) is sealingly clamped in like a sandwich between their circular and circumferential opening edges (6) and flange parts (11) in such a manner between the interconnected housing parts (1,8) that fluid can penetrate from one housing part (1) into the other housing part (8) only through the selectively permeable flat filter blank (7). The one housing part comprises threads (5) on the cylindrical outer edge of its opening edge facing the flat filter blank (7) and the connection of both housing parts (1,8) consists of a sprayed-on plastic ring (12) which holds the two housing parts (1,8) with flat filter blank (7) in a sealing and clamping position, completely fills up the threads (5) of the one housing part (1) and extends over the edge (11) of the other housing part (8) like a detachable union nut, so that a detachable housing connection is formed and the flat filter blank (7) can be removed from the filter housing for further testing.
