ABSTRACT:
A pneumatic vibrator is disclosed including a tubular housing having closed ends, an inlet port in the housing through which a fluid, such as air can flow into the housing, and a free-floating piston in the housing having two passageways through which the pressurized air entering the housing through the inlet port flows to act alternately against opposite ends of the piston and cause the piston to reciprocate in the housing. Exhaust ports are located in the housing through which the air ahead of the moving piston is exhausted from the housing. A plurality of relatively small openings is located in the housing through which pressurized air can flow into the housing and provide a fluid bearing between the piston and the housing, and means are provided to supply the inlet port opening with air under pressure.
