Patent ID: 7224103

Claim:
A cavitation system, comprising: a spherical cavitation chamber, comprising: a spherical external surface; and a spherical internal surface, wherein said spherical external surface and said spherical internal surface define a 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 said second end surface of said head mass is adjacent to a portion of said spherical external surface, wherein a threaded hole in said second end surface is surrounded by a first portion of said second end surface, wherein said first portion of said second end surface of said head mass is surrounded by a second portion of said second end surface of said head mass, wherein said second portion of said second end surface extends beyond said first portion of said second end surface, and wherein said second portion of said second end surface defines a ring of contact between an outer perimeter of said second end surface of said head mass and said spherical external surface; 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 first end surface of said head mass; and a second centrally located threaded means, wherein a first end portion of said second centrally located threaded means is threaded into said threaded hole in said second end surface of said head mass and a second end portion of said second centrally located threaded means is threaded into a corresponding threaded hole in said spherical external surface.
