Patent ID: 8490644

Claim:
A hydraulically powered hose winding apparatus, comprising: a support; a hose reel rotatably mounted on the support; a hose coupled to the hose reel, the hose winding about the hose reel when the hose reel is rotated in a first direction; a valve mechanism having an inlet port for receiving pressurized fluid from a pressurized fluid supply, an outlet port in fluid communication with the hose, a main conduit extending between the inlet port and the outlet port, and a turbine disposed along the main conduit between the inlet port and the outlet port; a gear mechanism having a first gear coupled to the valve mechanism and a second gear coupled to the hose reel, the first gear being coupled to the turbine so that rotary motion is transmitted from the turbine to the first gear when pressurized fluid flows through the valve mechanism, and the first gear transmitting rotary motion from the turbine to the second gear when pressurized fluid flows through the valve mechanism, thereby causing the hose reel to rotate in the first direction and the hose to wind about the hose reel; and a valve member disposed in the main conduit of the valve mechanism upstream of the turbine and a gear for actuating the valve member to incrementally close the main conduit when the hose reel is rotated in the first direction, thereby restricting pressurized fluid flow past the turbine and slowing rotation of the hose reel in the first direction as the hose winds about the hose reel.
