Abstract

PURPOSE: To make it possible to reduce noises, by locating sound-absorbing blates, extending radially from a center hub of a cylinder case, and by attaching fixedly adjacent rotary vane wheels at the one main shaft in such a manner that an axial distance between both rotary vane wheels is set so as to be in proportion to the wave length of standard frequency sound which the rotary vane wheels produce.
