Abstract
A description is given of a sanitary article or object, particularly a hand-operated shower, having a changeover device (2) for controlling a liquid flow, the sanitary article having a liquid inlet and a liquid outlet, as well as an air suction device which can be turned on or off by operating the changeover device in the manner of a water jet pump. The changeover device is so constructed that a passage cross-section formed between the liquid inlet (6) and liquid outlet (7) can be widened on turning off the air suction device. For this purpose, in addition to the pump jet opening (38) of the air suction device, it is possible to open a ring channel-like, further passage cross-section (30) arranged concentrically thereto. Whereas with the air suction device turned on and limited water consumption it is possible to produce a highly aerated, soft-feeling water jet, with the air suction device turned off roughly twice the water quantity can be delivered in the form of a powerful water jet suitable for massaging purposes.
