Abstract
A take-up reel for winding and storing an elongate hose or electrical cable comprises a reel that is rewound by a torsional spring. A viscous clutch is coupled to the reel by means of a unidirectional clutch, which engages the viscous clutch to the reel to rewind the reward speed, but disengages the viscous clutch from the reel when the hose or cable is being payed-out. This permits the hose or cable to be payed-out without resistance from the viscous clutch. The uni-directional viscous clutch assembly thus allows the hose to be payed-out at any speed while providing the substantial safety benefits of a viscous speed governor during rewind.
