  • Patent number: 7111795
    Abstract: A shower head with structural features for providing a water spray pattern having revolving characteristics is disclosed. The shower head includes an inlet assembly connectable to a water source and a cooperatively engaged outlet assembly including a body having a front facing surface, an impeller having a plurality of blades and a rotator assembly having a spray surface defining a plurality of spray apertures. The rotator spray surface forms a portion of the front facing surface. A seal spacer disposed between the inlet assembly and the front facing surface has a plurality of radially spaced ports. Each port is axially transverse to a plane of the seal spacer. Water flow through the ports creates a multi-directional water current downstream from the spacer to drive the impeller and consequently, cause rotation of the rotator spray surface and water emission in a revolving spray pattern.
