Abstract: A compressed air muffler comprises a rear attachment section, a compressed air muffler section adjoining it in the longitudinal direction with a compressed air muffler body of a porous compressed air muffler material and an outlet duct extending in the length direction as far as a front outlet opening, such outlet duct having in the muffler section, a form tapering toward the outlet opening. The muffler body has a bare outer peripheral face, its outer periphery face constituting an outlet face for the compressed air flowing through its wall athwart the longitudinal direction. The duct section extending through the attachment section, of the outlet duct merges steplessly with the duct section running in the muffler section.

Abstract: An additive atomizing device and further means and a method for the atomization of a liquid additive in a gaseous pressure medium, more particularly compressed air, flowing through a pressure medium flow duct (10). The additive is conveyed from one inlet (26) of an additive passage duct (24) for supplying the additive from an additive supply means (27 and 28) to an outlet (25) opening into the pressure medium flow duct (10). A detecting means (17 and 18) detects at least one physical characteristic in the pressure medium flow duct (10) and signalizes same by way of a signalizing means (19 and 20) to a control means (21). The control means (21) controls a pressure producing device (43 and 47) in a manner dependent on the at least one physical characteristic found by the detecting means (17 and 18) by way of a control connection (23.
