Date Sep. 19, 1991.An expansion hose for power steering plants of motor vehicles. The hose includes an outer pressure hose (2) connected to an inlet side end member (1) and to an outlet side end member (3). An inner flexible hollow body (5) is arranged coaxially with pressure hose 2, and which at the inlet side is connected to a nipple plug (4) of the inlet side end member (1) and at the outlet side extends freely into the outlet side end member (3) in its outlet channel (6) with a radial clearance. The nipple plug (4) includes in addition to the axial passage (9) located at the center axial passages (10) at a radial distance outwardly therefrom and distributed circumferentially, and which lead into the annular space (8) between the outer pressure hose (2) and the inner flexible hollow body (5). A part (4a) of the nipple plug (4) formed as a hexagonal body and is pressed into the inlet side end member (1), whereby the passages (10), arranged on a circle, are formed through which the pressurized medium flows throttled into the annular space (8), into which annular space also lead a plurality of spaced radial passage openings (7) arranged distributed along the inner flexible hollow body (5).
