  • Patent number: 6105613
    Abstract: A distributor for a hydraulic hoist which is controllable with regard to position and applied force, for tractors and agricultural machines, comprises a compact body having at least one inlet duct for a pressurized fluid, at least one discharge duct and at least one duct for connection to a hydraulic cylinder for lifting the hoist arms. Arranged in the body of the distributor are a valve for modulating the flow of pressurized fluid and for communicating with the connecting duct by way of a main internal duct and a valve unit for discharging the fluid coming from the hydraulic lifting cylinder. A slider is movable inside the cylindrical body in two opposite directions with respect to a neutral position and controls the modulating valve hydraulically, preferably with the interposition of a consent valve. The slider also controls the discharge valve unit and a variable choke member arranged in the main internal duct.
