ABSTRACT:
A flexible hose take-up assembly for automatically retracting a flexible fluid dispensing hose is disclosed. A cabinet having an interior chamber at least partially filled with a damping liquid houses a pulley assembly and a pair of counterweights used to control flexible hose pay out and retraction. A flexible hose of the type used in automotive service centers is attached to the ends of the cable of the pulley assembly such that the hose is stored adjacent the exterior of the cabinet when in the stored position. The pulley assembly permits the movement of the counterweights carried by the pulley assembly, the counterweights being at least partially immersed in the damping liquid, in a first direction away from a home position within the cabinet in response to the movement of the flexible hose from its stored position to one of its fluid dispensing positions, and permits the gravitational movement of the counterweights through the liquid in a second direction back toward the home position in response to the release of the hose from its fluid dispensing position. The hydraulic damping imposed on the counterweights by the liquid provides a uniformly controlled rate of retraction and substantially eliminates hose snap-back during movement in the second direction.
