Abstract
An oil filter assembly includes a filter housing, an oil filter unit, and a drain valve unit. The filter housing is provided with an oil inflow passageway through which oil is supplied into the filter housing from an oil pan, an oil exhaust passageway communicating with a main oil gallery, and an oil drain passageway through which oil is drained to the oil pan. The oil filter unit is disposed within the filter housing to filter the oil flowing into the filter housing. The drain valve unit is configured to selectively close the oil exhaust passageway and the oil drain passageway in response to whether the oil filter unit is disposed within the filter housing or whether the oil filter is removed from the filter housing.
