Air line pipe for connecting passenger supply units in passenger aircraft, has adjustable air outlet comprising outer and inner pipes, which are frictionally connected with each other by relative rotation to each other

摘要

The pipe (12) has an adjustable air outlet comprising an outer pipe (14) and a telescopically insertable inner pipe (16) whose free ends are connected with respective passenger supply units (10a, 10b). The outer pipe includes two rotatably interconnected pipe sections (18a, 18b), where the inner and outer pipes are frictionally connected with each other by relative rotation to each other. The inner and outer pipes have a slightly oval cross-section, where the inner pipe exhibits outside markings i.e. colored rings, and is connected with a counterpart in an airtight manner.
