  • Shower heads
    Patent number: 4203550
    Abstract: A shower head comprises a water chamber and attachment means for connecting the water chamber to a water conduit. A rotor in the water chamber is rotated by swirling motion of the water and causes pulsating emission of water from holes in an end face of the water chamber. A movably mounted outer casing has windows formed therein to allow the pulsating emission through. Changing the position of the outer casing causes water to be emitted continuously from holes formed in the outer casing and sealed from the windows.
