Abstract:
1. A method of assembling at least two port assemblies in a cavitation chamber, the method comprising the steps of: boring a first cone-shaped port in a cavitation chamber wall of the cavitation chamber, wherein an external port diameter of said first port and associated with a cavitation chamber external surface is smaller than an internal port diameter of said first port and associated with a cavitation chamber internal surface; boring a second cone-shaped port in said cavitation chamber wall of the cavitation chamber, wherein an external port diameter of said second port and associated with said cavitation chamber external surface is larger than an internal port diameter of said second port and associated with said cavitation chamber internal surface; inserting a first member with a cone-shaped external surface corresponding to said first cone-shaped port through said second cone-shaped port into said cavitation chamber, wherein said first member is 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, and wherein said first diameter is smaller than said internal port diameter of said second port and larger than said external port diameter of said first port; positioning said first member in said first cone-shaped port; positioning a second member with a cone-shaped external surface within a corresponding cone-shaped internal surface of a mounting ring, said cone-shaped external surface of said second member defined by a third diameter associated with said cavitation chamber internal surface and a fourth diameter associated with said cavitation chamber external surface, wherein said third diameter is larger than said fourth diameter, and wherein said mounting ring has a cone-shaped external surface corresponding to said second cone-shaped port; positioning said mounting ring within said second cone-shaped port; and locking said mounting ring in place within said second cone-shaped port with a retaining ring.
