Abstract
The invention is concerned with an improvement in a winch and fluid control system. The preferred system which is improved comprises (1) a rotatable drum for receiving and releasing a cable (2) a drive train for supporting the drum and for selectively transmitting rotary drive thereto, said drive train including a brake. A source of pressurized fluid, forms another part of said system. Said system further comprises a control valve having an inlet communicating with said source of pressurized fluid, and having an outlet system and a valving element which is shiftable between at least three positions including a Brake-On position, a Reel-In position and a Brake-Off position. The improvement of the present invention comprises a normally engaged one-way clutch intermediate said brake and a stationary support therefor which always allows substantially unrestricted rotation of said drive train relative to said stationary support in a Reel-In direction and normally prevents rotation of said drive train relative to said stationary support in a Reel-Out direction; and means for selectively disengaging said brake to allow substantially unrestricted rotation of said drive train in said Reel-Out direction.
