Oil filter for the cleaning of lubricating oil |
摘要 |
An oil filter has a cap screwed to the approximately upright arranged filter housing of the oil filter for the cleaning of lubricating oil, with a ring-shaped filter insert being detachably fastened on the cap and separating the outer inflow space from the inner flow-off space. In the lower zone of the filter housing, provision is made for a valve-like acting member, which is automatically opened with each change of the filter insert and serves for discharging oil that remained in the filter housing into an oil-collecting space via a discharge duct. A center bar is rotatably connected with the cap. The center bar is axially displaceable in a limited way and has in its zone close to the cap a piston-like flange, which is sealed against the filter insert and separates the inflow space from the flow-off space. The center bar has, in its lower end zone, the valve-like acting member cooperating with the discharge duct.
