Abstract
A filter assembly includes a housing, a proximal end cap, and a nut plate. The housing defines a longitudinal axis and includes an inner surface surrounding the longitudinal axis. The proximal end cap is disposed within the housing and defines a central aperture. The nut plate is disposed within the housing and includes a flange portion and an outer wall. The flange portion is disposed within the central aperture. The outer wall includes a plurality of protrusions disposed about the longitudinal axis. At least one of the plurality of protrusions engages the inner surface to prevent rotation of the nut plate relative to the housing.
Claims21
A filter assembly comprising:
- a housing defining a longitudinal axis and including an inner surface surrounding the longitudinal axis;
- a proximal end cap disposed within the housing and defining a central aperture;
- and
- a nut plate disposed within the housing and having a flange portion and an outer wall, the flange portion disposed within the central aperture, the outer wall having a plurality of protrusions disposed about the longitudinal axis, at least one of the plurality of protrusions engaging the inner surface to prevent rotation of the nut plate relative to the housing.
A method of manufacturing a fluid filter assembly, the method comprising:
- providing a housing defining a longitudinal axis and having an inner surface;
- inserting a filter element within the housing;
- inserting a nut plate within the housing, the nut plate having a plurality of protrusions disposed about the longitudinal axis;
- engaging at least one of the plurality of protrusions with the inner surface to prevent rotation of the nut plate about the longitudinal axis relative to the housing;
- and
- engaging the inner surface of the housing with an end of the nut plate to secure the nut plate within the housing.
A filter assembly comprising:
- a housing defining a longitudinal axis and including an inner surface surrounding the longitudinal axis;
- and
- a nut plate disposed within the housing, the nut plate having a lower end, an upper end, and an outer wall extending between the upper end and the lower end, the lower end and the outer wall including a plurality of protrusions configured to engage the inner surface.
