A method and an apparatus for generating a pulsating air by communicating an air passage intermittently by rotating a valve (4, 4A, 4B) while feeding air into a casing or discharging air from the casing (3, 3A, 3B, 3C) by a blower (6) connected to a connecting port of the casing (2a - 2g). The air passage extends from the connecting port for the blower (2a - 2g) to a transmitting port (1, 1A, 1B) of the casing (3, 3A, 3B, 3C) for transmitting a pulsating air. The apparatus for generating a pulsating air is comprised of a casing (3, 3A, 3B, 3C) provided with a connecting port for a blower (2a - 2g) and a transmitting port for a pulsating air (1, 1A, 1B). The connecting port (2a - 2g) is connected with a feeding side of the blower (6) or a suction side of the blower (6). The valve (4, 4A, 4B) is designed to be operated so as to intermittently communicate the air passage. <IMAGE> |
