Patent ID: 7049730

Claim:
A cavitation system, comprising: a spherical cavitation chamber, comprising: an external surface defined by a spherical curvature; and an internal surface, wherein said spherical cavitation chamber external surface and said spherical cavitation chamber internal surface define a spherical cavitation chamber wall; an acoustic driver assembly coupled to said spherical cavitation chamber, comprising: at least one piezo-electric transducer; a tail mass adjacent to a first side of said at least one piezo-electric transducer; a head mass with a first end surface and a second end surface, wherein said first end surface of said head mass is adjacent to a second side of said at least one piezo-electric transducer and wherein said second end surface of said head mass has a spherical curvature equivalent to said spherical curvature of said spherical cavitation chamber external surface; and a first centrally located threaded means coupling said tail mass, said at least one piezo-electric transducer and said head mass together, wherein said first centrally located threaded means is threaded into a corresponding threaded hole in said head mass; and a braze joint coupling said second end surface of said head mass to a portion of said spherical cavitation chamber external surface.
