  • Winch with hydraulic motor especially for helicopter equipped with sonar
    Patent number: 5735506
    Abstract: A winch operates with a hydraulic motor which is supplied by a servo-valve. The servo-valve is connected as a 3-way system so that the supply hose used as a discharge when the load is being winched up is connected directly to the fluid return and so that during the descent, this motor is no longer supplied with high pressure and the fluid is circulated in a closed circuit without pressure. Fluid is refreshed with a flow rate low enough so that it does not excessively increase the supply of energy, but high enough that it limits the overheating of the fluid.
