Abstract
An oil filter adapter device may be used to enable an engine or other machine that was manufactured for using cartridge oil filters to use spin-on oil filters. In some examples, the oil filter adapter may have a docking collar for coupling with an engine, a cylindrical base for coupling with an oil filter housing, and an attachment piece for coupling with a spin-on oil filter. The oil filter adapter may also have a spring disposed between the docking collar and the cylindrical base such that the docking collar is compressible relative to the cylindrical base to allow the oil filter adapter is able to couple to a variety of oil filter housings ranging in size and shape.
Claims20
An oil filter adapter comprising:
- a cylindrical base having a first end for coupling to an engine and a second end for coupling to an oil filter, the cylindrical base having an unfiltered oil passage and a filtered oil passage;
- a cylindrical docking collar movably coupled to the cylindrical base, the cylindrical docking collar having:
- a first end comprising a retainer for coupling to the first end of the cylindrical base;
- a second end comprising a sealing face for coupling to the engine;
- and
- a passage through a center of the cylindrical docking collar in fluid communication with the filtered oil passage of the cylindrical base;
- and
- an oil filter attachment coupled with the second end of the cylindrical base and configured to couple with a spin-on oil filter.
An oil filter adapter comprising:
- a cylindrical base having a first end for coupling to an engine and a second end for coupling to an oil filter, the cylindrical base having a passage for unfiltered oil and a passage for filtered oil;
- a docking collar movably coupled with the first end of the cylindrical base and partially received in the passage for filtered oil;
- a spring interposed between the docking collar and the passage for filtered oil such that the docking collar is compressible into the passage for filtered oil;
- a first oil filter attachment coupled with the second end of the cylindrical base for transporting unfiltered oil;
- and
- a second oil filter attachment coupled with the second end of the cylindrical base for transporting filtered oil.
An oil filter adapter comprising:
- a cylindrical base having a first end for coupling to an engine and a second end for coupling to an oil filter;
- a cylindrical docking collar movably coupled to the cylindrical base, the cylindrical docking collar having:
- a first end comprising a retainer for coupling to the cylindrical base, the retainer comprising a first rubber O-ring;
- a second end comprising a sealing face for coupling to the engine, the sealing face comprising a second rubber O-ring;
- a passage through a center of the cylindrical docking collar in fluid communication with a filtered oil passage of the cylindrical base;
- and
- at least one oil filter attachment coupled with the second end of the cylindrical base.
