Drainage system for a hollow space/water box in a car bodywork has a sealing element in a drain hole and a drainage opening

摘要

A sealing element (100) is held in a car bodywork drain hole (11) so as to seal a peripheral side. A seal closes up a drainage opening (101) in the sealing element and, when pressure is applied, is moved into an outlet position by water collected in a hollow space/water box.
