Abstract
A shower head jet disk (4) has inlet and outlet openings (8, 9) on opposite sides, with a passage duct (10a, 10b) fluidically connecting each outlet to at least one inlet. An upstream control disk (2) is rotatable relative to the jet disk and has a control slot pattern (131, 134) opening the inlets depending on the rotational position of the control disk. The control slot pattern and the inlets are coordinated such that two adjacent inlet openings (8a, 8b) that correspond with a common outlet opening (9) via two passage ducts (10a, 10b) with non-parallel side walls (12a, 12b) provide different jet outlet directions (Sa, Sb), or two regions of an inlet opening that corresponds with an outlet opening via a passage duct with non-parallel side wall regions provide different jet directions, or two adjacent inlet openings that correspond with two adjacent outlet openings are opened, in alternating fashion.
