The valve enables connection between a pressure outlet (13) of the air pump and the chamber in another position. Valve chambers (16-18) comprise freely movable valve bodies (19-21), which takes an end position associated with the former position of the valve, and another end position associated with the latter position of the switching valve. Motion of the bodies is mechanically released between the end positions by a level of fluid in the chamber. Independent claims are also included for the following: (1) a domestic appliance i.e. washing/drying appliance, comprising a chamber pump (2) a method for operating a chamber pump.
