Coupling for two fluid-containing components esp. washing fluid pipes of windscreen washer units of motor vehicles consists of two parts, with conical shoulder on one part and sealing ring locked against shoulder

摘要

The device has two coupling parts locked together sealing. The inner part (3) is mushroom-shaped with a reduced-size conical part, and the outer part (2) has a sealing ring. A cylindrical or conical shoulder is formed on the front of the smaller part. The taper angle of the conical shoulder is smaller than that of the reduced-size part, and when the sealing ring (15) is in locked position, it engages elastically tensioned in the transitional area between the shoulder and the reduced-size part. A U-shaped locking element (4) engaging on a stop shoulder (14) on the inner coupling part can be elastically expanded and is contained in a holder (8) in the wall of the outer coupling part.
