ABSTRACT:
An ultrasonic liquid delivery device in which a housing of the device has an internal chamber and at least one exhaust port in fluid communication with the internal chamber of the housing. A valve member is moveable relative to the housing between a closed position in which liquid is inhibited against exhaustion from the housing via the at least one exhaust port, and an open position in which liquid is exhaustable from the housing via the at least one exhaust port. An ultrasonic waveguide separate from the housing and valve member is disposed at least in part within the internal chamber of the housing to ultrasonically energize liquid within the internal chamber prior to liquid being exhausted from the housing in the open position of the valve member. An excitation device is operable in the open position of the valve member to ultrasonically excite the ultrasonic waveguide.
