Filter Element Having Dual Filtration Capacity and Filter Assembly

摘要

A filter element may include a tubular member including a partition at least partially defining first and second chambers. The partition may be configured to prevent flow communication between the first and second chambers within the tubular member. The tubular member may further include an inlet port configured to provide flow communication into the first chamber, and an outlet port configured to provide flow communication from the second chamber. The tubular member may also include at least one outlet aperture configured to provide flow communication out of the first chamber, and at least one inlet aperture configured to provide flow communication into the second chamber. The filter element may also include a filter medium associated with the at least one outlet and inlet apertures. The filter element may be configured such that fluid passing through the filter element passes through both the first chamber and the second chamber.

1. A filter element comprising:
a tubular member having a longitudinal axis and including:
a partition at least partially defining a first chamber and at least partially defining a second chamber, the partition extending longitudinally in the tubular member and being configured to prevent flow communication between the first chamber and the second chamber within the tubular member;an end portion at least partially defining an inlet port configured to provide flow communication into the first chamber, and at least partially defining an outlet port configured to provide flow communication from the second chamber;at least one outlet aperture in the tubular member configured to provide flow communication out of the first chamber; andat least one inlet aperture in the tubular member configured to provide flow communication into the second chamber; and a filter medium associated with the at least one outlet aperture and the at least one inlet aperture, wherein the filter element is configured such that fluid passing through the filter element from the inlet port to the outlet port passes through both the first chamber and the second chamber.
