Patent abstract
An acoustic fluid machine has an acoustic resonator and a piston reciprocated by an actuator at the base of the acoustic resonator. A valve device is provided on the upper end of the acoustic resonator. External air is introduced into the acoustic resonator through the valve device. The piston has through-holes, through which front space communicates with rear space thereby reducing load applied onto the piston.
