Embodiment Construction

[0020] The filter device 1 according to the invention comprises a filter housing formed by a bottom plate 2, a top plate 3 and a cylindrical wall 4 located between the plates. Wherein the bottom plate 2 and the top plate 3 are connected to the cylindrical wall 4 by means of screws, which are schematically indicated by the axis 5 in the figure. To ensure a seal between the bottom plate 2 and the cylindrical wall 4 and between the top plate 3 and the cylindrical wall 4 , O-ring seals 6 are provided.

[0021] Inside the filter housing, there is a first or bottom sealing element 8 and a second or top sealing element 9 tightly mounted on the bottom plate 2 by means of drill-through hollow bolts provided with two sealing rings. A filter insert 10 is arranged between the end sealing elements 8 and 9 . The filter element 10 comprises filter paper 11 wound on a wound core 12, which may also comprise a large number of layers of tissue paper. The winding core 12 is provided with holes ...

Abstract

The invention relates to a filter device for microfiltration of oil, in particular for use in engines, automatic transmissions and hydraulic applications. The filter device comprises a tubular microfilter cartridge through which medium can flow in the transverse direction and which has open ends. This filter cartridge is accommodated in a filter chamber which is enclosed by a filter housing and is accommodated between two end closure elements, between which the filter cartridge is clamped under prestress. On their surface facing towards the filter cartridge the end closure elements are provided with at least one rib which extends in the transverse circumferential direction of the filter cartridge. The holding means comprise a spring which acts with prestress on one of the end closure elements, in such a manner that his closure element follows the end wall which it adjoins in the event of longitudinal expansion and also in the event of longitudinal contraction.

Description

technical field [0001] The invention relates to a filter device for microfiltration of oil, especially in engines, automatic transmissions and hydraulic systems, the filter device comprises a microporous tubular filter element having an open end and allowing media to flow laterally; a A filter housing enclosing a filter chamber in which the above-mentioned filter element is or can be accommodated in such a manner that the filter chamber is divided into a first space outside the filter element and a second space inside the filter element, these spaces being passed through The tubular walls of the filter element used as a filter communicate with each other; the filter housing is provided with a first end sealing element and a second end sealing element for closing the open end of the filter element and at least partially or completely overlapping the end of the filter element on the wall; and the filter housing is provided with fixing means for sandwiching the filter element bet...
