Patent ID: 6857773

Claim:
A compressed gas operated vibrator that includes: a cylindrical housing, having a raceway located therein, the raceway being sized for guiding a rolling member along an orbital path interior of the cylindrical housing, a first end cap for closing a first end of the cylindrical housing and a second end cap for closing a second end of the cylindrical housing, at least one of either the first end cap or second end cap being removably retained thereon, the cylindrical housing further including at least one inlet port for directing a flow of a compressed gas to and towards a selected point of the raceway, an outlet port for exhausting gas from the housing, and a turbine wheel that is carried on a shaft that extends from the first end cap to the second end cap, the shaft being selectively positioned for allowing rotation of the turbine wheel interior of the cylindrical housing, the turbine wheel having a plurality of blade members formed along its outer diameter, the turbine wheel further including a recess portion that is formed into its outer diameter, the recess portion being selectively sized for allowing the rolling member to reside therein while simultaneously allowing the rolling member to contact the raceway; and wherein, the turbine wheel with the rolling member residing in the recess portion therein rotates interior of the cylindrical housing by the action of the compressed gas thereby generating an unbalanced vibratory motion and the turbine wheel minimizing unwanted acceleration of the rolling member as and when the orbiting rolling member is directly acted upon by the flow of compressed gas at the location of the inlet port for minimizing damage to the rolling member and the raceway.
