Abstract
A shower head for a hand-held shower attachment, an overhead shower attachment or a side shower attachment contains, in its shower-head housing, a vortex chamber which is of funnel shape with the side wall curved. The funnel begins, at the location of the largest diameter, in a radial plane and then decreases in diameter along a curved contour to an exit, where the walls of the funnel run in the axial direction. At the location of the largest diameter of the vortex chamber, upstream of this tapering region, the water is let in tangentially in the circumferential direction and in the axial direction. The vortex which is generated by virtue of the water being let in tangentially accelerates its speed of rotation in the direction of the spray disc. Arranged at the end of the tapering region is a jet-outlet chamber which is very flat, but is of large diameter in relation to the vortex chamber. The vortex travels into this jet-outlet chamber, and therefore, even in the outer region, water jets exit with a massage action out of the jet-outlet openings which are present there.
