Abstract
A noise damper for a compressed air device includes a tubular housing part provided with an air inlet and an inserted insulating material, in particular, an inserted knitted fabric roll. The air inlet is embodied in the envelope of the tubular housing part such that the supplied air tangentially flows through the insulating material or the knitted fabric roll, is radially deviated inside the tubular housing part, and axially flows out from at least one end of the tubular housing part.
Claims32
A noise damper for a compressed air device, comprising a tubular housing part having an air inlet, an air outlet, a jacket and sound damping material disposed therein, said air inlet being defined in said tubular housing part to direct a flow of incoming air through a portion of said sound damping material substantially tangential to said portion, and radially deflecting said air through said portion such that said air spirals axially there-through and out from at least one end of said tubular housing part.
A noise damper for a compressed air device, comprising a tubular housing part having an air inlet, an air outlet, a jacket and sound damping material disposed therein, wherein said tubular housing part is closed at ends thereof, said air inlet being defined in said tubular housing part to direct a flow of incoming air substantially tangentially relative to said sound damping material, wherein said air is radially deflected inside said tubular housing part such that said air flows axially out from at least one end of said tubular housing part.
