Abstract
The application discloses a collection vessel for a condenser of an air-conditioning system, preferably for motor vehicles. The collection vessel 1 holds in its interior a drier that can be exchanged via an opening which can be closed by means of a releasable lid. The lid is designed as a piston-like, cylindrical stopper , and be sealed and guided in an axially displaceable manner in a corresponding hole in the collection vessel . The stopper is pressed outwardly against a securing ring by the internal pressure (pi) in the vessel, which securing ring is fixed in an annular groove in the collection vessel and is secured against release by a blocking shoulder on the stopper . Due to this measure, the lid of the collection vessel cannot be removed when pressure is prevailing inside the vessel. Only when the vessel is depressurized can the securing ring and therefore also the stopper be removed, so that a drier cartridge can be exchanged.
