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.
A shower head comprising a mouthpiece (1) having a central, axial, throughgoing channel (8) for flow-through of water, whereby a rotationally symmetrical deflector element (6) for the water is situated in the vicinity of the outer mouth of the channel, the mouthpiece (1) being in threaded connection with a support (2) through which the water is supplied and is adapted to be adjusted axially relatively to the support, while the deflector element (6) is carried by a stem (3) which with a radial clearance extends axially in the channel and is fastened to the support (2), characterized in that the deflector element (6) on the side facing the channel (8) has a concave circumferential groove (6') having a curved cross section around the stem (3), and that the region of the mouthpiece (1) around the deflector element (6) or immediately axially inside thereof, provides a conical surface (7) which extends converging outwardly and turns into a mainly cylindrical surface nearest to its free end, there being an annular gap (4) between the deflector element (6) and the conical surface (7).
