Filter with rotational end cap base retention

摘要

A filter includes a filter element mounted to a base and having first and second end caps spaced axially along an axis. Fluid to be filtered flows laterally through the filter element and axially through a hollow interior and through an axial flow opening of the second end cap. The filter element is mounted to the base solely by the second end cap in rotational relationship independently of the first end cap, eliminating the third component traditionally needed for mounting a housing cover to the base and enclosing and/or sealing and/or retaining the filter element in the housing.
