Abstract
A multifunction hand shower can be used in at least two modes of operation: in the first of these modes of operation, the shower jets emerge from the shower base (3) in a constant stream at relatively high speed and with a small cross-section ('hard jet mode') and in the second mode of operation they emerge at high speed and with a relatively small cross-section, but are intermittently interrupted ('pulse jet mode'). The periodic interruption of the 'pulse jets' is ensured by a pulse wheel (23) which is housed in a circular chamber (20) in the housing (1) in such a way that it can rotate. In the 'hard jet mode', the rotation of the pulse wheel (23) is interrupted, by a stop (45), in a quite specific angular position which allows the hard jets to emerge from the shower base (3) in a constant stream. To change over to 'pulse jet mode', the stop (45) is moved out of the path of movement of a stop (28) which is connected to the pulse wheel (23) such that the pulse wheel (23) is now able to rotate freely. The paths taken by the water inside the housing (1) and especially the water outlet openings (4) through which the water flows are the same in the 'hard jet mode' and the 'pulse jet mode'.
