Patent ID: 7073258

Claim:
A method of assembling a port assembly in a cavitation chamber, the method comprising the steps of: boring a cone-shaped port in a cavitation chamber wall of a first cavitation chamber piece of the cavitation chamber, wherein the cavitation chamber is comprised of multiple cavitation chamber pieces including said first cavitation chamber piece, wherein an external port diameter associated with a cavitation chamber external surface is smaller than an internal port diameter associated with a cavitation chamber internal surface; locating a mounting ring with a cone-shaped external surface corresponding to said cone-shaped port within said multiple cavitation chamber pieces, said mounting ring having an internal cone-shaped surface defined by a first diameter associated with said cavitation chamber internal surface and a second diameter associated with said cavitation chamber external surface, wherein said second diameter is smaller than said first diameter; joining said multiple cavitation chamber pieces together to form the cavitation chamber, wherein said mounting ring is located within said cavitation chamber prior to completion of said joining step; placing a member with a cone-shaped external surface corresponding to said internal cone-shaped surface of said mounting ring within said cavitation chamber, said cone-shaped external surface of said member defined by a third diameter corresponding to said cavitation chamber internal surface and a fourth diameter corresponding to said cavitation chamber external surface, and wherein said third diameter is smaller than said external port diameter; pulling said mounting ring into said cone-shaped port; and pulling said member into said mounting ring.
