ABSTRACT:
A method and an apparatus for generating a pulsating air by communicating an air passage intermittently by rotating a valve while feeding air into a casing or discharging air from the casing by a blower connected to a connecting port of the casing. The air passage extends from the connecting port for the blower to a transmitting port of the casing for transmitting a pulsating air. The apparatus for generating a pulsating air is comprised of a casing provided with a connecting port for a blower and a transmitting port for a pulsating air. The connecting port for the blower is connected with a feeding side of the blower or a suction side of the blower. The valve is designed to be operated so as to intermittently communicate the air passage.
