Abstract

A crankcase ventilation element is provided. The element includes a plate including a first port. The first port extends from the plate in a first direction. The element includes a housing coupled with the plate. The housing defines an axial centerline. The housing includes a second port extending from the housing in a second direction opposite the first direction. The housing includes a flange extending around a perimeter of the housing. The flange includes a sealing surface. The element includes a filter media disposed between the plate and the housing. The first port and the second port intersect the axial centerline. The first port is axially offset from the second port. The first port is laterally offset from the second port.

First claim

What is claimed is:

1 . A crankcase ventilation element, comprising:
a plate comprising a first port, the first port extending from the plate in a first direction; a housing coupled with the plate, the housing defining an axial centerline, the housing comprising:
a second port extending from the housing in a second direction opposite the first direction; and
a flange extending around a perimeter of the housing, the flange comprising a sealing surface; and
a filter media disposed between the plate and the housing, wherein:
the first port and the second port intersect the axial centerline;
the first port is axially offset from the second port; and
the first port is laterally offset from the second port.

2 . The crankcase ventilation element of claim 1 , wherein the first port defines an inlet opening to receive a fluid and a drain to drain a contaminant separated from the fluid.

3 . The crankcase ventilation element of claim 2 , wherein the first port comprises an inner surface and an outer surface, the inlet opening disposed adjacent to and spaced apart from the inner surface, and the drain extending through the inner surface and the outer surface.

4 . The crankcase ventilation element of claim 1 , wherein the first port defines a port centerline and comprises a plurality of drains, the plurality of drains disposed asymmetrically around the port centerline.

5 . The crankcase ventilation element of claim 1 , wherein:
the flange defines a plane; and the first port comprises an inlet sealing element disposed an inlet seal distance away from the plane, wherein the inlet seal distance is approximately 39 mm.

6 . The crankcase ventilation element of claim 5 , wherein the second port comprises an outlet sealing element, the outlet sealing element disposed an outlet seal distance away from the plane, the inlet seal distance greater than the outlet seal distance.

7 . The crankcase ventilation element of claim 6 , wherein the outlet seal distance is approximately 14.5 mm.

8 . The crankcase ventilation element of claim 1 , wherein:
the flange comprises a first elongated portion and a second elongated portion, the first elongated portion and the second elongated portion defining the axial centerline therebetween; and the first port is disposed closer to the second elongated portion than the first elongated portion.

9 . The crankcase ventilation element of claim 8 , wherein a center of the first port is offset from the axial centerline a lateral offset distance, wherein the lateral offset distance is approximately 7.2 mm.

10 . The crankcase ventilation element of claim 1 , wherein the housing comprises a first end and a second end, the first port disposed a first distance from the first end and a second distance from the second end, the first distance less than the second distance.

11 . The crankcase ventilation element of claim 1 , wherein the crankcase ventilation element comprises no drain opening external to the first port.

12 . The crankcase ventilation element of claim 1 , wherein the plate further comprises a plenum, a majority of the plenum disposed on a first side of the axial centerline and a majority of the first port disposed on a second side of the axial centerline, the first side opposite the second side.

13 . The crankcase ventilation element of claim 1 , wherein the flange of the housing comprises:
a first side comprising:
a first elongated portion;
a first angled portion transitioning from the first elongated portion; and
a first curved portion transitioning from the first angled portion; and
a second side comprising:
a second elongated portion;
a projection transitioning from the second elongated portion, the projection extending away from the first side;
a second angled portion transitioning from the projection; and
a second curved portion transitioning from the second angled portion, the second curved portion transitioning into the first curved portion.

14 . A crankcase ventilation element, comprising:
a plate, comprising:
a plate body; and
a first port extending from the plate body in a first direction, the first port comprising a first sealing element; and
a housing coupled with the plate, the housing comprising:
a first end;
a second end opposite the first end;
a flange extending around a perimeter of the housing, the flange comprising a seal surface, the seal surface defining a plane; and
a second port disposed proximate to the first end of the housing, the second port extends from the housing away from the plate in a second direction opposite the first direction, the second port comprising a second sealing element,
wherein the first sealing element is disposed a first seal distance from the plane and the second sealing element disposed a second seal distance from the plane, the second seal distance greater than the first seal distance; and wherein the first port is disposed closer to the first end of the housing than the second end.

15 . The crankcase ventilation element of claim 14 , wherein:
the plate comprises a plenum extending from the plate body to the first port, the plenum comprising a separator configured to separate a contaminant from a fluid; and the first port defines an inlet opening configured to receive the fluid and a drain configured to drain the contaminant separated from the fluid out of the crankcase ventilation element.

16 . The crankcase ventilation element of claim 15 , wherein the crankcase ventilation element comprises no drain external of the first port.

17 . The crankcase ventilation element of claim 15 , wherein the housing defines an axial centerline, and wherein a majority of the plenum is disposed on a first side of the axial centerline and a majority of the first port is disposed on a second side of the axial centerline.

18 . The crankcase ventilation element of claim 14 , wherein:
the housing defines an axial centerline; and the first port and the second port intersect the axial centerline.

19 . The crankcase ventilation element of claim 18 , wherein the first port is laterally offset from the second port by a port offset distance, the port offset distance being approximately 7.10 mm.

20 . The crankcase ventilation element of claim 13 , wherein:
the first port comprises an inlet sealing element, the inlet sealing element disposed an inlet seal distance away from the plane; the second port comprises an outlet sealing element, the outlet sealing element disposed on outlet seal distance away from the plane; and the inlet seal distance is greater than the outlet seal distance.
