Bypass and full flow combination filter

A filter for filtration of oil and/or fuel comprising a combination of a bypass filter portion and a full flow filter portion wherein,

• the bypass filter portion has a bypass filtration medium and the full flow filter portion has a full flow filtration medium;
• the filter has an inlet port enabling entry of oil or fuel to the full flow filtration medium encircling a return channel through which the oil or fuel may exit the filter;
• a bypass inlet is located within the return channel enabling entry of oil or fuel to the bypass filter portion;
• and
• a restriction orifice is disposed at a forward end of the bypass filter portion, between the bypass inlet and the bypass filtration medium, thereby allowing a controlled volume of fluid to pass into the bypass filtration medium for filtration before exiting the filter.
