Lubricating oil filter for ic. engines

摘要

Lubricating oil filter, partic. for use in ic. engines,with the following features. The vertical filter chamber (1) is closed at the top by a screwcap (2) which secures the filter carrier (3) with its concertina-folded filter element (4) in a central position. Raw oil is passed into the chamber at (8) and clean oil is removed at (10). In addition a central drain (12), which is normally closed, passes both raw and clean oil when cap (2), together with the attached carrier (3), is removed. Filter element (4) fits at its lower end on an abutment which separates the chambers for raw and clean oil, oil flowing radially through the element. Support tube (5) which is part of carriers (3) is generally perforated to allow cleaned oil to pass into it. It is however solid at its bottom end to form a dividing wall between the two chambers. The clean oil exit (10) lies below this wall and the carrier in this region has a cruciform section.
