Abstract
A filter element may include a tubular member including a partition at least partially defining first and second chambers. The tubular member may further include at least one outlet aperture and at least one inlet aperture configured to provide flow communication exiting from the first chamber and flow communication into the second chamber, respectively. The filter element may be configured such that fluid passing through the filter element from an inlet port to an outlet port passes through the first chamber, a filter medium, and the second chamber. The filter element may also include an end cap having a return aperture configured to provide flow communication between fluid exiting from the first chamber and fluid entering the inlet port, wherein a portion of fluid exiting from the first chamber is returned to the inlet port for recirculation through the first chamber.
