    摘要： An anti-roll stabilizer device for boats includes a container adapted to be mounted on a suspension so as to oscillate around a first axis; a mass rotatably supported inside the container so as to form a rotor that rotates around a second axis transverse to the first axis; and a rotor cooling system having a hollow shaft arranged along the second axis, a first and a second cooling chamber sealed from the container of the rotor and from the outside, arranged at the ends of the hollow shaft and communicating through the hollow shaft, the first chamber having an inlet and the second chamber an outlet that are connected to a forced circulation circuit of the cooling fluid so that the cooling fluid can circulate from the first chamber to the second chamber through the hollow shaft and from the second chamber to the first chamber through the circulation circuit.

    摘要： A hydraulic steering device for boats, vessels or the like, includes a hydraulic pump coupled to a drive motor to feed a drive fluid alternately according to two flow directions; a hydraulic actuating cylinder connected to the delivery and return of the pump; and a fluid flow distributor switching the connection of the delivery and suction of the pump alternatively to one of two inlets/outlets of the cylinder communicating with one of two chambers of the cylinder. The actuating cylinder is mechanically articulated to a steering member, which determines direction change by modifying its orientation relative to an axis of the boat, the vessels or the like, preferably to a longitudinal axis, the modification of steering member orientation being implemented by the actuating cylinder according to the supply of the drive fluid to the cylinder caused by operation of the pump. The motor has inputs for a power supply signal to drive the pump to supply fluid flow according to one of the two predetermined directions of flow.

    摘要： A device for controlling reverse gears, particularly of marine engines, includes a fixed part and a movable part, the movable part being adapted to be rotatably coupled to a control member having at least three operating states corresponding to a first, a second and a third angular position of the movable part of the device. The fixed part includes at least one first and one second sensor, for example of the type generating a voltage when subjected to an external magnetic field due to Hall effect, which are arranged at predetermined distance and configured to detect the presence of a magnetic field. The movable part comprises a magnet with such characteristics to generate a magnetic field detected by the first or second sensors when the movable part is in the first or second positions respectively or vice versa, the third position corresponding to a situation of absence of magnetic field detectable by the sensors.

    摘要： Steering control system for a watercraft with a steering tiller manually operated and operatively connected to a direction changing member acting on or into the water, such as a rudder plate or an outboard motor; a device locking the steering tiller in the steering position. which can be activated for maintaining the tiller in a predetermined angular position and can be deactivated for allowing the tiller to be moved in a different angular position to carry out a change in the direction. The locking device is of the hydraulic type, that is, oil-hydraulic type, and includes a hydraulic cylinder having a rod that is fastened stationary to the transom of the watercraft and a cylindrical body that is movable along the rod and is connected to a steering arm of the motor or of the rudder member, or vice versa, there being provided a closed circuit for flowing the oil between the two chambers of the cylinder, within which circuit there is provided a valve opening and closing the circuit, which locking device can be activated/deactivated by an actuator that opens/closes the valve opening and closing the circuit. The system further includes an interposition element between the steering tiller and the watercraft direction changing member, the tiller being pivotably articulated to such element, and a member transforming the pivoting movement of the tiller with respect to the interposition element into commands actuating the valve.

    摘要： A steering system for a boat, a marine vessel or the like, having an outboard motor with an underwater propeller and a removable fastening terminal at the hull, includes a steering control member, such as a steering wheel, a rudder bar or a rudder wheel, and an actuator that changes the orientation of the propeller by changing the angular position of the rotation axis thereof relative to the longitudinal axis of the boat. An intermediate framework, positioned between the stationary part of the boat and the fastening terminal of the engine, includes a housing for at least a portion of the drive assembly and/or of the actuator fastened to the intermediate framework.
