    摘要： A blower muffling apparatus includes a blower chamber (26) for housing a blower (VB) therein, an exhaust chamber (32) positioned adjacent the blower body side of a blower disposed in the blower chamber, communicating in one of upper and lower portions with the blower chamber, and having an exhaust port in the other portion, a muffling passage chamber (30) disposed adjacent the blower chamber in the axial direction of the blower, and having one end communicating with the other portion of the exhaust chamber and the other end communicating with a discharge port of the blower through a flexible exhaust duct, and a duct accommodating chamber (36) for accommodating the flexible exhaust duct therein, each of the chambers being surrounded by a sound-absorbing material. Exhaust gas of the blower is discharged from the flexible exhaust duct through the muffling passage chamber (30) and the exhaust chamber (32) to thereby absorb exhaust noise of the blower.

    摘要： The present invention relates to a vortex flow blower used as an air source to be incorporated into general industrial machines. The vortex flow blower according to the present invention is characterized in that the shape of the blade in its impeller is three dimensionally formed such that at least the inner portion of the blade can be adapted to the three dimensional internal flow. According to the present invention, the aerodynamic performance can be significantly improved and the size of a vortex flow blower can be reduced. Furthermore, an impeller having three dimensionally shaped blades is manufactured by independently manufacturing the shroud and the blades and coupling them, so that the impeller of a complicated shape can be readily manufactured. Furthermore, since the blade can be made of a thin and light material, the secondary moment of inertia of the impeller can be reduced.
