Abstract
A multiple aspirator has a disk with an axial hole and a plurality of radial bores, providing liquid feeding channels, which end at the axial hole. A round rod is disposed coaxially in the axial hole. Gas flow parallel to the axis, through the hole past said disk, is forced by the rod into an annular pattern, thereby aspirating fluid from the radial bores and nebulizing it in said annular pattern.
