Multifunction hand shower

A multifunction hand shower in which at least two modes of operation can be selected in which the shower jets emerge at a relatively high speed and with a relatively small cross-section, namely in a first mode of operation in which the shower jets emerge in a constant stream and a second mode of operation in which the shower jets are periodically interrupted, which comprises:

• (a) a housing;
• (b) a shower base which seals the housing and which has a number of water outlet holes;
• (c) a pulse wheel which is mounted in a circular chamber in the housing through which water flows so that it is capable of rotation and which, as it turns, periodically interrupts and then frees the through-flow of water to the appropriate water outlet openings in the shower base;
• (d) a change-over mechanism to select the mode of operation which comprises:
• i) a manual actuator;
• ii) at least one first change-over device controlled by the manual actuator, which can be moved into at least two different positions and in this way determines the mode of operation of the shower,
• in which the first change-over device acts on a stop which, in the first position of the first change-over device, is located outside the path of movement of a stop mounted on the pulse wheel and which, in the second position of the first changeover device, is located in the path of movement of the stop on the pulse wheel such that the pulse wheel stops in a specific position of rotation,
• the change-over mechanism being designed to set a third mode of operation in which air shower jets emerge from the shower base at relatively glow speed and have a relatively large cross-section.
