Abstract

A pump sleeve includes a tubular body extending from a first end to a second end along a center axis. A first hole is formed in the tubular body and is positioned axially on the tubular body between the first end and the second end. A second hole is formed in the tubular body, the second hole being axially aligned on the tubular body with the first hole. A third hole is formed in the tubular body and is positioned axially on the tubular body between the first end and the first hole. A fourth hole is formed in the tubular body, the fourth hole being axially aligned on the tubular body with the third hole.

First claim

The invention claimed is:

1. A pump sleeve comprising:
a tubular body extending from a first end to a second end along a center axis;
a first hole formed in the tubular body and positioned axially on the tubular body between the first end and the second end;
a second hole formed in the tubular body, wherein the second hole is axially aligned on the tubular body with the first hole;
a third hole formed in the tubular body and positioned axially on the tubular body between the first end and the first hole;
a fourth hole formed in the tubular body, wherein the fourth hole is axially aligned on the tubular body with the third hole;
a fifth hole formed in the tubular body and positioned axially on the tubular body between the first end and the third hole; and
a sixth hole formed in the tubular body, wherein the sixth hole is axially aligned on the tubular body with the fifth hole;
wherein the first hole and the second hole are both wider in a direction of the center axis than the third hole and the fourth hole; and
wherein the third hole and the fourth hole are both wider in the direction of the center axis than the fifth hole and the sixth hole.

2. The pump sleeve of claim 1 , wherein the first end of the tubular body is open.

3. The pump sleeve of claim 2 , wherein the second end of the tubular body is open.

4. The pump sleeve of claim 2 , wherein the first end of the tubular body further comprises a mounting flange.

5. The pump sleeve of claim 1 , further comprising:
a first slot formed on the tubular body,
wherein the first slot is axially aligned on the tubular body with the first and second holes, and
wherein the first slot is disposed circumferentially on the tubular body between the first and second holes.

6. The pump sleeve of claim 5 , further comprising:
a second slot formed on the tubular body,
wherein the second slot is axially aligned on the tubular body with the third and fourth holes, and
wherein the second slot is disposed circumferentially on the tubular body between the third and fourth holes.

7. The pump sleeve of claim 6 , further comprising:
a third slot formed on the tubular body,
wherein the third slot is axially aligned on the tubular body with the fifth and sixth holes, and
wherein the third slot is disposed circumferentially on the tubular body between the fifth and sixth holes.

8. The pump sleeve of claim 1 , wherein the first, second, third, fourth, fifth and sixth holes are equal in dimension in a direction of a circumference of the tubular body.

9. The pump sleeve of claim 1 , further comprising:
a first groove formed on an inside surface of the tubular body proximate the first end; and
a second groove formed on the inside surface of the tubular body proximate the second end.

10. A pump sleeve comprising:
a tubular body extending from a first end to a second end along a center axis;
a first hole formed in the tubular body and positioned axially on the tubular body between the first end and the second end;
a second hole formed in the tubular body, wherein the second hole is axially aligned on the tubular body with the first hole;
a third hole formed in the tubular body and positioned axially on the tubular body between the first end and the first hole;
a fourth hole formed in the tubular body, wherein the fourth hole is axially aligned on the tubular body with the third hole;
a fifth hole formed in the tubular body and positioned axially on the tubular body between the first end and the third hole;
a sixth hole formed in the tubular body, wherein the sixth hole is axially aligned on the tubular body with the fifth hole;
a first groove formed on an inside surface of the tubular body proximate the first end; and
a second groove formed on the inside surface of the tubular body proximate the second end.

11. The pump sleeve of claim 10 , wherein the first hole and the second hole are circumferentially offset on the tubular body from the third, fourth, fifth, and sixth holes.

12. The pump sleeve of claim 11 , wherein the third hole and the fourth hole are circumferentially offset on the tubular body from the fifth and sixth holes.
