ABSTRACT:
The piezoelectrically driven diaphragm of an air pump is extended through a chamber and commmunicating outlet passage of the pump's housing. During vibration of the diaphragm, air pulses are alternately expelled through the outlet passage portions positioned on opposite sides of the diaphragm. The air pulses are collected in a rectifying device, carried by the housing, for delivery to a fluidic device or system.
