Abstract
A pulsating vibration air generator in which wave height, frequency and wave shape of the pulsating vibration air can be optionally modified and such pulsating vibration air can be periodically and continuously emitted. The pulsating vibration air generator has a valve chamber with an inlet port and an outlet port where a valve plug and a valve seat with a control opening are provided and a cam mechanism which moves the valve plug to open or close the opening of the valve seat, whereby positive or negative pulsating vibration air is emitted from the outlet port while pressurized air is supplied into the inlet port or air is sucked from the inlet port.
