Abstract

A cover with a center axis for a pump assembly includes a plate. A center hole is formed in the plate and positioned on the center axis of the cover. A first edge of the plate extends between a first lobe and a second lobe, a second edge of the plate extends between the first lobe and a third lobe, and a third edge of the plate extends between the second lobe and the third lobe. The first, second, and third lobes each comprise a mounting boss with a thru-hole.

First claim

The invention claimed is:

1. A cover with a center axis for a pump assembly comprising:
a plate;
a center hole formed in the plate and positioned on the center axis of the cover;
a first edge of the plate extending between a first lobe and a second lobe;
a second edge of the plate extending between the first lobe and a third lobe; and
a third edge of the plate extending between the second lobe and the third lobe,
wherein the first, second, and third lobes each comprise a mounting boss with a thru-hole,
wherein the first edge and the second edge are straight, and
wherein the third edge is bent away from the center hole on a plane of the plate.

2. The cover of claim 1 , wherein the third edge is longer in length than the first edge.

3. The cover of claim 2 , wherein the second edge is longer in length than the first edge.

4. The pump assembly of claim 3 , wherein the first edge and the second edge of the plate are positioned equidistant from the center axis.

5. The cover of claim 1 , wherein the plate of the cover is generally triangular in shape.

6. A pump assembly comprising:
a tubular body extending from a first end to a second end along a center axis, wherein the first end is open;
a plurality of pumps disposed within the tubular body; and
a cover connected to the first end, wherein the cover comprises:
a plate;
a center hole formed in the plate and positioned on the center axis of the tubular body;
a first edge of the plate extending between a first lobe and a second lobe;
a second edge of the plate extending between the first lobe and a third lobe; and
a third edge of the plate extending between the second lobe and the third lobe,
wherein the first, second, and third lobes each comprise a mounting boss with a thru-hole,
wherein the first edge and the second edge are straight, and
wherein the third edge is bent away from the center hole on a plane of the plate.

7. The pump assembly of claim 6 further comprising:
a drive shaft connected to at least one of the plurality of pumps and extending through the center hole of the plate of the cover.

8. The pump assembly of claim 6 , wherein the plate of the cover is generally triangular in shape.

9. The pump assembly of claim 8 , wherein the second edge is positioned at an angle of approximately 66 degrees to approximately 70 degrees from the first edge.

10. The pump assembly of claim 9 , wherein the third edge is longer in length than the first edge.

11. The pump assembly of claim 10 , wherein the second edge is longer in length than the first edge.
