ABSTRACT:
An air blast generator is provided in the form of a pressure accumulator with a spring-loaded bellows. Air pressure expands the bellows, compressing the spring to store energy. When a valve is opened the spring aids in expulsion of the air such that a high pressure discharge of air is provided for a larger duration than would be possible without the spring.
