摘要	PURPOSE: To obtain a stabilized speed profile of gas flow while suppressing generation of turbulence by employing a nozzle having parallel plane for determining the speed profile of gas flow. CONSTITUTION: When AC power is fed to a piezoelectric diaphragm, the diaphragm oscillates to generate a fluid pressure pulsation in a pump chamber defined in a supporting member 74. Consequently, the fluid is pressurized through an orifice 72 to concentrate the hydraulic pressure in a drain chamber 52. The chamber 52 discharges the fluid through a supply port 25, a manifold chamber 24 and a fluid supply pipe 26 into inlet manifold chamber 27 thence into a nozzle 28. The cubic feet/min(CFM) current velocity of fluid depends on the dimensions and profile of pump chamber. Fluid velocity Vp in a jet chamber 29 depends on the cross-sectional area (A) of nozzle.
