Fluid driven screw type (moyno) sonic oscillator system

摘要

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.
