Abstract
A water flow operated device for winding and/or unwinding a length of flexible material. The device includes a stationary element, a spool with a central axis rotatably engaged by the stationary element and a water flow operated mechanism engaged by the stationary element. The water flow operated mechanism serves to controllably rotate the spool. The water flow operated mechanism includes a water operated motor, a water inlet communicable with a household water source, a water outlet and a valve for controlling a flow of water through the mechanism.
Claims16
A water flow operated device for winding and/or unwinding a length of flexible material, the device comprising:
- (a) a stationary element;
- (b) a spool having a central axis, said spool being rotatably engaged by said stationary element and being rotatable about said central axis;
- and
- (c) a water flow operated mechanism being engaged by said stationary element for controllably rotation said spool, said water operated mechanism including:
- (i) a water operated piston motor having at least two water operated pistons mechanically linked to said spool, and a distribution valve assembly for selectively directing water to said pistons so as to rotate said spool;
- (ii) a water inlet for directing water into said water flow operated mechanism, said water inlet being communicable with a household water source;
- (iii) a water outlet for directing water out of said water flow operated mechanism;
- and
- (iv) a control valve for controlling a flow of water through said water flow operated mechanism.
A water flow operated device for winding and/or unwinding a length of flexible material, the device comprising:
- (a) a stationary element;
- (b) a spool having a central axis, said spool being rotatably engaged by said stationary element and being rotatable about said central axis;
- and
- (c) a water flow operated mechanism being engaged by said stationary element for controllably rotating said spool by connection to an output linkage, said water operated mechanism including:
- (i) a static-pressure-responsive water operated motor configured for driving said output linkage through unlimited revolutions;
- (ii) a water inlet for directing water into said water flow operated mechanism, said water inlet being communicable with a household water source;
- (iii) a water outlet for directing water out of said water flow operated mechanism;
- and
- (iv) a valve for controlling a flow of water through said water flow operated mechanism,
- wherein said valve has at least two operation states including a first operation state in which said valve directs water into said water flow operated mechanism for subsequent release to a drain and a second operation state in which said valve directs water away from said water flow operated mechanism, wherein said second operational state directs water to a channel in fluid communication with a hose.
