Detailed Description

According to an embodiment of the present invention, there is provided an end cap for an open end of a filter housing, the end cap comprising a disc-shaped portion having a top surface, a bottom surface, and a central opening extending through the top and bottom surfaces, the disc-shaped portion having a hollow cylindrical portion extending from the top surface; the cylindrical portion having a bottom end connected to the top surface and communicating with the central opening, a top end, and an outer sidewall; the outer sidewall includes at least one plurality of outwardly extending rounded features.

In a preferred embodiment, the plurality of outwardly extending radiused structures are linearly arranged at an angle relative to the axis A-A of the end cap.

In an exemplary embodiment, the end cap includes two pluralities of outwardly extending rounded structures arranged about 180 ° apart on the outer sidewall.

In a preferred embodiment, the top end of the cylindrical portion contains a groove in the outer sidewall, and the end cap may further include a seal disposed in the groove.

Each component of the present invention will now be described in more detail below, wherein like components have like reference numerals.

In the illustrated embodiment of the invention, the end cap 100 includes a disc-shaped portion 1 having a top surface 11, a bottom surface 12, an axis a-a from the top surface to the bottom surface, and a central opening 10 extending through the top and bottom surfaces, the disc-shaped portion having a hollow cylindrical portion 20 extending from the top surface; the cylindrical portion has a bottom end 22 connected to the top surface and communicating with the central opening, a top end 21, and an outer sidewall 24; the exterior sidewall includes at least one grouping 50 of a plurality of outwardly extending rounded structures 50'. Typically, the rounded structure is annular or elliptical, or is generally annular or generally elliptical.

In a preferred embodiment, the top end 21 of the cylindrical portion contains a groove 25 in the outer sidewall, and as shown in fig. 7, the end cap may further include a seal 75 (shown as an O-ring) disposed in the groove.

Various seals are suitable for use in embodiments of the present invention, preferably the seal comprises an O-ring.

Preferably, as shown in FIG. 4, the plurality of outwardly extending radiused structures are linearly arranged at an angle relative to the central axis of the end cap. In some embodiments, this angle improves the operation of screwing the end cap (which is attached to the filter housing of the filter assembly) into the mating groove of the manifold, and in those embodiments where the end cap contains a group of two sets of rounded structures and the top end of the cylindrical portion contains a groove in the outer sidewall and a seal disposed in the groove, when the end cap is rotated, this angle improves the efficiency of pulling the end cap into the manifold and the seal is compressed and seated into the mating sealing surface of the manifold.

In the illustrated embodiment, the end cap contains two

sets

50A, 50B of a plurality of outwardly extending rounded structures arranged 180 ° apart. Typically, each set comprises a grouping of at least three outwardly extending rounded structures, and in the illustrated embodiment, each set comprises five outwardly extending

rounded structures

51, 52, 53, 54, 55.

Typically, the bottom surface of the end cap may be thermally bonded to one or more of: a filter housing, a shroud, a core, and/or a filter pack or filter element.

A variety of materials are suitable for use in manufacturing end caps according to embodiments of the present invention. In a preferred embodiment, the end cap is polypropylene.

As will be appreciated by those skilled in the art, the diameter, thickness and profile of the disc-shaped portion of the open end cap can be varied to receive different filter diameters or to vary according to the requirements of the manufacturing operation (e.g., end-capping to assemble the filter element). The diameter of the cylindrical portion may be varied to fit different manifold outlets and to receive different sized seals. The groups of outwardly extending radiused structures, each group arranged to form part of the threads, can be adjusted by varying the size, shape, number and arrangement of the structures to fit different manifold outlet configurations. The open end cap may be attached to a plenum connecting the outlets of the plurality of filters to the open end cap.
