Patent ID: 7406765

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 the cavitation chamber, said cone-shaped port defined by a first diameter associated with a cavitation chamber internal surface and a second diameter associated with a cavitation chamber external surface, wherein said first diameter is smaller than said second diameter; positioning a 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 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 cone-shaped port; positioning said mounting ring within said cone-shaped port; and locking said mounting ring in place within said cone-shaped port with a retaining ring.
