ABSTRACT:
The disclosure is directed to a flexible fluid line arrangement suited for connecting a hand held fluid-driven appliance to a source of motive fluid in a manner providing reliable, effective fluid supply, while permitting easy and facile manual manipulation of the appliance. The application specifically discloses a water driven power toothbrush adapted for connection to a household faucet. Concentrically arranged tubes connect the faucet with the hand held appliance, with the pressure side of the faucet connected to the innermost tube, while the exhaust or discharge side connects to the annular space between the inner and outer tubes. Novel, simplified swivel connections are provided between the appliance and the concentric tubes, and also between the tubes and the outlet fitting at the faucet.
