摘要： The invention relates to a filter element comprising a supporting pipe (10) permeable to fluids which is surrounded by a mat filter (12) which in turn is enclosed by a filter casing (16) which has openings (18) and delimits a filter chamber (14). The filter element further comprises two end caps (20, 22) arranged on the faces. Because the filter casing (16) consists of a plastic casing formed from an even blank the two ends (24, 26) of which are bent towards each other and firmly joined together by means of a sealing seam (28) formed by a heat sealing-, heat element-, or ultrasonic welding method, thus forming the filter chamber (14), a filter element is created which is economical to produce and which is more suitable for being recycled in its entirety.

摘要： The invention relates to a tubular filter element and to a device for producing the same for filtering fluids. Said filter element comprises a filter mat (10) whose facing ends (14) are fixed in position by a connecting device (16) which at least partially overlaps said ends (14). The connecting device (16) consists of a thermally deformable plastic and is welded to the ends (14) of the filter mat (10). The connecting device (16) is configured as a connection strip in the form of a clip (18), is slid onto the filter mat ends (14), and holds these together for a thermal welding process. When the clip (18) is in the melted-on state, it is joined to the filter mat ends (14) without using welding supplements. A particularly strong and durable connection of the filter mat ends (14) is realized by virtue of the fact that the plastic clip (18) is embossed at least along one or both of its limbs (24) during a thermal welding such that the filter mat ends (14) are welded to one another in compressed manner.

摘要： The invention concerns a filter device with a bypass valve (20) which, releases a fluid-conveying path to an outlet when a filter element (14) becomes clogged and comprises a closure part (22) on which at least one closure spring (24) acts. According to the invention, in order to adjust the spring pretension and hence the opening force for the closure part (22), an adjusting device (28) is provided for adjusting the opening force of the respective closure spring (24). As a result, a filter device is provided which can be economically adapted without any structural modifications to very different applications in a predetermiend pressure range.
