Quick change oil filter

Abstract:

A quick change oil filter includes a filter canister and filter base that may be installed and removed manually from an engine adapter on an internal combustion engine. The filter canister and filter base may hold at least about one third of the required engine oil supply when removed from the engine adapter. The engine adapter includes an oil inlet passage, an oil outlet passage, and a filter base mounting cavity. A check valve is biased to close an oil outlet opening from the filter canister, trapping oil inside the filter canister when it is removed from the engine adapter.
