Abstract
Abstract A screw shaped rotor is freely mounted for rolling rotation in a mating screw shaped stator which is mounted in a housing. The rotor is rotatably driven by means of a fluid stream to generate sonic energy in the housing with a lateral mode of vibration at a frequency which is the function of the rate of fluid flow. The oscillator housing is coupled to the load which it drives uniformly along the entire length of the oscillator. The drive fluid for the oscillator is coupled thereto through a flexible coupling such as a section of rubber hose so that this coupled end of the oscillator is not substantially constrained against lateral vibration and is free to vibrate laterally along with the rest of the housing. The oscillator housing may be coupled along its entire length to the load to be vibrationally driven or can be suspended in a liquid which is to be vibrationally energized.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A system for providing sonic vibrational energy to a load comprising: an orbital oscillator including a housing, an elongated screw shaped stator mounted in said housing and an elongated screw shaped rotor mounted for precessionally rolling rotation freely in said stator; a fluid inlet formed in one end of said housing; a fluid outlet formed in the end of said housing opposite said one end thereof; means for supporting said housing; liquid drive means fed into said fluid inlet and exited from said fluid outlet for rotatably driving said freely mounted rotor at a rolling precessional speed such as to effect orbital lateral sonic vibration of said housing; and means for coupling substantially the entire extent of said housing to said load to transfer said sonic vibration thereto in a uniform in-phase manner through the coupling between the housing and the load; said rotor drive means and said means for supporting said housing being coupled to said rotor and said housing respectively so as to effect minimal constraint to the lateral vibration of said housing.
