Abstract: A water powered massager 10 comprised of a diviter valve 30 connected to a shower head 20 that diverts water into a hose 40 having an inlet channel 180 and an outlet channel 190 and is connected to a body 60. The water flows from the diviter valve 30, through the inlet channel 180 and into the body 60. Within the body 60 is a propeller 210 inside a propeller cavity 230. As water is introduced into the propeller cavity 230 from the inlet channel 180, it turns the propeller 210 and then exits the propeller cavity 230 back into the hose 40 in the outlet channel 190. The water travels through the outlet channel 190 back to the diviter valve and out to the nozzle 300 of the shower head 20. A flex plate 80 is attached to the body 60 and vibrates as a result of the water inside the propeller cavity 230. As the propeller 210 turns due to the force of the water, it rotates a central pin 220 which in turn rotates a rotating disk 160. The rotating disk 160 is adjacent to and in communication with a pulsating disk 150.
