Abstract
The present invention relates to a filter element comprising an oil filter port adapted to be in fluid communication with an oil port of an engine the oil filter port includes threads for attaching the filter element in the oil port of the engine. Thus, the inventors realized that by providing the oil port with threads, the oil port of the filter element may be tightened in the oil port of the engine to in this way ensure axial locking of the filter element in the engine. The present invention also relation to a corresponding filter housing.
Claims14
A filter element for an oil filter, configured to be releasably lockable in a filter housing comprising a locking mechanism, the filter element comprising:
- a filter medium mechanically connected to an upper end plate, the filter medium being adapted to capture contaminants in oil passing through the filter medium;
- a cylindrical oil filter port adapted to be in fluid communication with an oil port of an engine to return filtered oil to the engine, the cylindrical oil filter port is arranged on one distal end of the filter element and is comprised in and extends away from the upper end plate to reach into the oil port of the engine, the cylindrical oil filter port includes threads formed in an outer surface of the cylindrical oil filter port configured to engage with threads of the engine oil port of the engine for attaching the cylindrical oil filter port filter element in the oil port of the engine;
- and
- a locking mechanism for locking the filter element in place in the filter housing;
- wherein the locking mechanism is a circumferential locking mechanism arranged on a cylindrical flange and arranged on the other distal end of the filter element, on an opposite side of the filter medium and including at least one locking member having a locking portion configured to prevent a counter rotation.
An oil filter, comprising:
- a filter housing comprising threads adapted for attaching the filter housing to an engine;
- and
- a filter element configured to be releasably lockable in the filter housing comprising a locking mechanism, the filter element comprising:
- a filter medium mechanically connected to an upper end plate, the filter medium being adapted to capture contaminants in oil passing through the filter medium;
- a cylindrical oil filter port adapted to be in fluid communication with the oil port of an engine to return filtered oil to the engine, the cylindrical oil filter port is arranged on one distal end of the filter element and is comprised in and extending away from the upper end plate to reach into the oil port of the engine, the cylindrical oil filter port includes threads formed in an outer surface of the cylindrical oil filter port to engage with threads of the engine oil port of the engine for attaching the cylindrical oil filter port in the oil port of the engine, wherein the lead of the threads in the oil port of the filter element are substantially equal to the lead of threads on the filter housing;
- and
- a locking mechanism for locking the filter element in place in the filter housing.
