Abstract: The invention relates to a filter device (10) for filtering a liquid, in particular a hydraulic oil, having a substantially cylindrical filter housing (12), which accommodates a filter element (30) and can be closed off by means of a cover (18), the filter element (30) having an associated untreated region (70) with an inlet (22) for supplying liquid which is to be filtered and a clean region (74) with an outlet (26) for removing filtered liquid, and the filter element (30) comprising an end plate (58) which is remote from the cover (18) and on which there is mounted a radially acting sealing element (62) for sealing the untreated region (70) of the filter element (30). To develop a filter device of this type in such a manner that it can be produced at lower cost and can be assembled more easily, according to the invention it is proposed that the sealing element (62) comprises a radially protruding sealing lip (64) which bears against the inner side of the filter housing (12) and is inclined toward the untreated region (70) of the filter element (30).

Abstract: A pipe extension for a filtering pot of a return filter has an outlet connection projecting from the filtering pot at its free end and a pipe secured to the outlet connection. An annular groove extending in circumferential direction is arranged at the outlet connection and an annular seal which does not protrude radially beyond the outer circumference of the outlet connection is inserted into the annular groove. Radially projecting, axially extending conical webs are provided at the outer circumference of the pipe connection in the region between the annular groove and the filtering pot and a pipe consisting of metal is pushed onto these webs, whereby the pushed-on pipe is expanded by the conically extending webs to achieve a secure seat. A bead reaching into the annular groove is introduced into the pushed-on pipe.
