Flow limiter and use of a flow limiter in an air distribution system of an air conditioning system of an aircraft

摘要

A flow limiter comprises a line segment with an air inlet and an air outlet and at least one resistance element. The resistance element is positioned within the line segment and impresses a predetermined flow resistance on an air flow that extends from the air inlet to the air outlet. Preferably, the resistance element extends at least in part in an axial direction of the line segment. Such a flow limiter is used to adjust an air volume flow and comprises particularly low generation of intrinsic noise.

1. A flow limiter, comprising
a line segment with an air inlet and an air outlet; at least one resistance element, which resistance element is at least in some regions perforated so as to comprise a plurality of openings and at least in part comprises a curvature, a conical shape or the shape of a conical section; at least one absorber; and an air-impermeable covering element for covering some of the plurality of perforation openings while leaving the remaining perforations open for calibrating the flow resistance of the flow limiter, said covering element having a shape adapted to the shape of the resistance element, wherein the resistance element is positioned within the line segment and imposes a predetermined flow resistance on an air flow that extends from the air inlet to the air outlet; wherein the absorber is positioned downstream of the resistance element in the line segment.
