ABSTRACT:
A pneumatic vibrator is provided which operates without the use of bearings. The vibrator includes a generally cylindrically formed housing and a cylindrical shaped rotor contained within the housing. The housing includes an inlet for receiving pressurized fluid and an outlet for discharging the fluid. The rotor has a number of jets formed adjacent the periphery of the rotor and extending through the outer longitudinal surface thereof. The rotor also includes an axle member extending from the rotor and which engages a recess formed in an end of the housing. In operation, the inlet of the vibrator is connected to a source of pressurized air. At least a portion of one of the jets is aligned with the inlet to receive the pressurized air. The air discharged from the jet produces a thrust driving the rotor about the inner wall of the housing. As the rotor rolls in the housing, each jet in sequence is aligned with the inlet and receives pressurized air while the axle member moves adjacent the inner wall of the recess so that some portion of the outer longitudinal surface of the rotor remains in contact with a portion of the inner wall of the housing. The rotor thereby continues to roll against the inner wall of the housing and the impacting therebetween causes vibrations.
