FILTER ELEMENT HAVING VENT TUBE AND FILTER ASSEMBLY

摘要

A filter element may include a tubular member, including a first end portion, with the first end portion being substantially open, at least partially defining an inlet port configured to provide flow communication into a first chamber of the tubular member, and at least partially defining an outlet port configured to provide flow communication from a second chamber. The tubular member may further include a second end portion, with the second end portion being located at an end of the tubular member opposite the first end portion. The tubular member may also include at least one outlet aperture, at least one inlet aperture, and a vent tube extending longitudinally between the first end portion and the second end portion. The vent tube may be configured to provide flow communication between the first end portion and the second end portion of the tubular member.

1. A filter element comprising:
a tubular member having a longitudinal axis and including:
a first end portion, the first end portion being substantially open, at least partially defining an inlet port configured to provide flow communication into a first chamber of the tubular member, and at least partially defining an outlet port configured to provide flow communication from a second chamber, the second chamber not being in flow communication with the first chamber within the tubular member;a second end portion, the second end portion being located at an end of the tubular member opposite the first end portion;at least one outlet aperture in the tubular member configured to provide flow communication out of the first chamber;at least one inlet aperture in the tubular member configured to provide flow communication into the second chamber; anda vent tube extending longitudinally between the first end portion and the second end portion, the vent tube being configured to provide flow communication between the first end portion and the second end portion of the tubular member; 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.
