  • Patent number: 4809382
    Abstract: A hand spray has rotating brushes and consists of a housing with an inlet for the supply of water. In the housing an annular distribution chamber is delimited by means of a cup-shaped inner housing member, within which a turbine wheel is mounted. The turbine wheel is impinged by water flowing from the chamber through nozzles provided in the cup-shaped housing member. The turbine wheel drives the brushes via a gear transmission. In order to obtain a washing effect by means of regular jets simultaneously with the brushing effect of the rotating brushes, a circular array of holes is provided in the part of the housing facing away from the bottom of the cup-shaped housing member, the inner ends of said holes opening into the housing substantially flush with the inner side of the wall of the cup-shaped housing member, the outer ends of the holes opening directly into the open. The brushes of the hand spray are aranged within said circular array of holes.
