1. In a shower head having means for selectively discharging therefrom, alternatively, a shower spray from a first set of apertures or a pulsating shower spray from a second set of apertures, wherein the shower head includes an upstream axially elongated shell with a water inlet, a manually operable spray selector on the shell, a downstream housing as a part separate from the shell and from which water is discharged as said sprays, and diverter means between said shell and housing for selectively directing the discharging water either from the first or second set of apertures, the improvement comprising, in combination:

  • an axially-elongated diverter body, separate from said shell and downstream housing and positioned therebetween, said diverter body being shaped to provide an elongated, radially extending, control sleeve open at both ends, said diverter body also defining axially extending and radially offset intake and outlet flow passageways which intersect said control sleeve;

    an elongated diverter shaft pivotably mounted in said control sleeve with a portion of said shaft adjacent one end thereof extending radially through said shell to said manually operable spray selector seal means carried on said diverter shaft adjacent said one end and providing a rotary seal both between said shaft and the diverter body and between the shaft and the shell to prevent water leakage therepast, the other end of said diverter shaft being constructed to permit water flow therepast, and diverting seal means carried on said diverter shaft for sealing engagement with the wall of the control sleeve, and being shaped to direct flow from the intake flow passageway in the diverter body either radially outwardly from the control sleeve or to the outlet flow passageway in the diverter body upon selective rotation of the diverter shaft; and

    said shell, diverter body, and downstream housing being shaped, constructed, and arranged to provide, alternatively, a first water flow path through the shower head communicating with said first set of apertures or a second flow path through the shower head communicating with said second set of apertures, depending on the position of the pivotable diverter shaft controlled by the spray selector.
