Embodiment Construction

[0014] An acoustic fluid machine is formed by mounting the actuator 2 below the larger diameter of the base of the resonator 1 and the valve arrangement 3 to the smaller diameter upper end of the resonator 1 .

[0015] The resonator 1 has a resonant cavity 4 having a lower end with a larger diameter, and the diameter gradually decreases towards the top. The size of the resonant cavity 4 is such that when the length from the lower end to the upper end is about 100, the diameter of the upper end is about 5, and the diameter of the lower end is about 35.

[0016] The actuator 2 also serves as a support platform and reciprocates the piston 5 connected to the actuator 2 . A piston 5 is manufactured from light alloy and fitted in the lower end of the resonance chamber 4 , the outer periphery of which is equipped with a seal 6 .

[0017] The outer portion 19 of the surface of the piston 5 slopes gradually upwards from the center 18 .

[0018] The resonator 1 has an outward flange 7...

Abstract

The acoustic fluid machine includes resonator, valve unit, piston and executor. The resonator has base part in relatively great diameter and upper part in relatively small diameter; the valve unit is set in the upper end of the resonator and has sucking hole and exhaust hole; the piston set inside the base part of the resonator and has upper end plane in basically unchanged distance to the upper end of the resonator; and the executor is connected to the piston and makes the piston move reciprocally in high speed and relatively small axial amplitude, so that gas vibrates on the pressure of the resonator and is sucked into the resonator via the sucking hole and exhausted via the exhaust hole.

Description

technical field [0001] The present invention relates to acoustic fluid machines for gases that utilize acoustic resonance based oscillations in the magnitude of pressure changes. Background technique [0002] In the acoustic fluid machinery in the prior art, the piston reciprocates through the high-speed axial small amplitude of the actuator, the piston is arranged at the base of the larger diameter of the resonator, and the gas is sucked into the resonator and reciprocated by the accompanying piston through the upper end of the smaller diameter The pressure within the resonator oscillates to discharge from it. [0003] This acoustic fluid machine utilizes oscillation in the amplitude of pressure change of a standing acoustic wave generated by air column resonance in a tube accompanying the movement of the piston when the piston axially reciprocates with a very small amplitude, and includes only an actuator as an operating part, The actuator causes a piston in the base of t...
