ABSTRACT:
Secondary and tertiary air passages through the air nozzle surround the primary compressed air passage and induce a flow of low pressure air which surrounds the stream of compressed air to reduce the noise to acceptable levels. When the outlet end of the nozzle is blocked, flow through the tertiary air passages reverses to allow the compressed air to escape therethrough.
