Claim:
A method of providing an integrated valve sleeve comprising the steps of: providing a cylinder of malleable material having a first part, a second part, and a third part, wherein both the first part and the second part have a diameter; reducing the diameter of the first part of the cylinder to be less than the diameter of the second part of the cylinder; raising the second part of the cylinder in a first location in a direction away from the first part of the cylinder, wherein the first location of the second part of the cylinder defines a first raised wall; expanding the third part of the cylinder in a direction substantially perpendicular to both the first part and the second part, wherein expanding the third part of the cylinder further comprises expanding the third part of the cylinder in a first portion of the cylinder between the first part of the cylinder and the second part of the cylinder by compressing the first part of the cylinder in an axial direction toward the second part of the cylinder; and raising the second part of the cylinder in a second location in a direction away from the first part of the cylinder, wherein the second location of the second part of the cylinder defines a second raised wall; wherein the cylinder has a mass and all of the first part, second part, third part, first raised wall, and second raised wall are formed from the cylinder material.
