Abstract

The air is suctioned through a filter (2) into a first chamber, guided into the turbine and released after being compressed into a second chamber. The relation between the position of the outlet at the turbine and the outlet (3) of the second chamber as well as a layer of foam rubber (7) attached to all inner surfaces of the housing (1) results in a remarkable reduction of the noise normally created by the device. The surface of the rubber layer (7) is either plane or ribbed depending on its position in order to increase the noise absorbing effect.
