Abstract
An acoustic compressor has an acoustic resonator and a piston reciprocated by an actuator at a base of the acoustic resonator. A valve device is provided on the upper end of the acoustic resonator. The valve device comprises a suction chamber and a discharger chamber. External air is fed through an inlet to the suction chamber and sucked into the acoustic resonator through the suction bore. Then, the air in the resonator is compressed by the reciprocating piston. The discharge chamber has a discharge bore and an outlet to the outside. An outward nonreturn valve is larger in valve-opening resistance than an inward nonreturn valve in the suction bore. When the air pressure in the resonator exceeds a certain value, the high-pressure air is transferred to the discharge chamber through the discharge bore by allowing the outward nonreturn valve to open and then discharged through the outlet to the outside.
