BYPASS OIL FILTER ADAPTER

摘要

An adapter (10) for connecting a bypass oil filter to an internal combustion engine (14) having a full flow lubricating system is mounted between the oil filter mounting block (12) and the conventional full flow filter (16). The adapter includes means (48, 52) for diverting a portion of the circulating oil flow to the bypass filter and means (46, 74, 76) for returning that portion to the engine. The adapter includes a body portion (36) and an insert (60) which together define the passages necessary for diverting a portion of the oil flow to the bypass filter. The body includes a central axial (38) opening which receives the insert, the body and insert together defining an annular chamber (76) which receives clean oil from the bypass filter through a radial passage (46) in the body. An axial passage (68) in the insert allows clean oil to flow from the full flow filter to the engine and a plurality of radial passages (74) allow clean oil from the bypass filter to enter the axial passage (68) regardless of the relative orientations of the insert and the body. Additional passages are formed in the body to provide the remaining flow paths necessary for the bypass flow.
