  • Patent number: 5685489
    Abstract: A shower head includes a mouthpiece having a central, axial, throughgoing channel for flow-through of water. A rotationally symmetrical deflector element for the water is situated in the vicinity of the outer mouth of the channel. The mouthpiece is in threaded connection with a support through which the water is supplied and is adapted to be adjusted axially relatively to the support. The deflector element is carried by a stem which extends axially in the channel with a radial clearance and is fastened to the support. On the side facing the channel, the deflector element is concave, in that a circumferential groove having a curved cross section extends around the stem. The region of the mouthpiece around the deflector element provides a conical surface which extends converging outwardly. The shower head reduced water consumption at low water pressure and also permits pulsating showering.
