ABSTRACT:
A shower head has a body forming a rear compartment pressurizable with water and a forwardly open mouth having an inner periphery and an end disk generally closing the mouth, extending perpendicular to an axis, and having an elastically deformable outer rim formed with a plurality of axially through-going and radially outwardly open grooves opening rearwardly into the compartment and radially outwardly closed by the body. The rim further is formed with an annular and elastically deformable lip projecting axially past a downstream face of the disk and a downstream end of the body. The grooves are formed in the lip. Thus the critical downstream ends of the flow passages constituted by the grooves are formed in an elastically deformable lip that can be deformed. Since the deposits are normally very hard, such deformation of the lip will flake any lime deposits off.
