defined by an upstream surface 191 of an accessory disk 190 the rotator assembly 192 includes the accessory disk 190 which is press fit onto the rotator 195 a downstream facing surface 196 of the rotator defines ten small spray apertures 197 a 197 b water flowing into the impeller and exiting the tubular hub flows into the rotator assembly and out the 10 spray apertures referring again to fig2 the inlet assembly 12 has a metal ball joint 55 to which a tubular nut 50 is connected the metal ball joint 55 includes at an upstream end a hexagon nut connection having internal female threads the inlet assembly allows for rotation of the shower head about a shower inlet pipe fig5 shows a cross sectional view of the shower head 10 including a schematic representation of water flow through the inlet and outlet assembly 12 14 as seen in fig5 a user may manipulate a dial ring 90 having a thumb tab 91 to divert water to at least one of three flow passages a first flow passage represented by arrows in fig5 illustrates water flow through the rotator 195 which produces the revolving flow pattern illustrated in fig1 water enters the ball joint 55 and passes through a flow restrictor 35 as shown a gasket 65 maintains the downstream end of the ball joint in a sealed position with the housing 70 the tubular nut 50 and the annular lining 60 allow the shower head housing 70 to be rotated about the ball joint 55 as water enters the housing 70 along a center axis a c water is diverted off the center axis as.
