In one embodiment, a watercraft control apparatus according to the present invention includes a control member that operates a power-consuming unit or load. The control member is operably connected to the power-consuming unit or load through a drive member that transmits a control force and/or a displacement from the control member to the power-consuming unit or load. The watercraft control apparatus further includes an actuator for actuating the power-consuming unit and a magnetic unit for transducing the force and/or the displacement of the control member into a corresponding electric/electronic signal for a corresponding operation of the actuator.

The invention relates to an hydraulic device for the synchronized steering of at least a pair of marine outboard motors (7, 8), comprising an hydraulic cylinder (6) steering a main motor (7) sliding along a rod (10) parallel to the axis of the tube (9) tilting said motor (7), it is connected to an arm (13) steering said motor (7) by means of an articulated linkage (12), it is rotatable about at least an axis, and by means of articulated linkage (24, 29, 35) it is connected to an arm (17) steering a secondary motor (8). According to the invention, the device comprises a slide guide (14, 14′) stationary associated to the secondary motor (8) which is parallel to the axis of the tube (15) tilting it, and an axial steering slider (16, 16′) that can slide on said guide (14, 14°) and by means of articulated linkage (29, 36) it is connected to the pivotable end of the arm (17) steering the secondary motor (8), and it is slidably driven by means of at least a bar (24, 35) articulately connected with an end to the steering slider (16, 16′) and with the other end connected to the cylinder (6) steering the main motor (7).
摘要:
A method for fabricating a stranded cable particularly for mechanical motion transmission, which cable is composed of multiple strands or wires, helically wound around a common longitudinal axis, including the steps of: a—winding the strands that form the cable in a helical arrangement around a common longitudinal axis, b—flattening and smoothing the exterior profile of the each strand of the cable. Cable produced by that method.

Control device with a control mechanism for setting operation conditions of an engine and/or of other operating units. The control mechanism is movable along a predetermined path for a predetermined travel between two end-limit stop positions. A setting device sets an engine supply and/or operation parameters of other operating units. The setting device has at least a mobile setting mechanism, for example, a carburetor throttle is connected to the control mechanism by mechanical transmission. A movement thereof causes a movement of the setting mechanism. The system further provides a movement and/or position sensor on the control mechanism. The sensor produces electrical signals univocally correlated to the position/movement of said control mechanism. A motor actuator operating the setting mechanism is connected to a control gearcase. The gearcase produces control signals of the actuator univocally correlated and corresponding to signals transmitted by the position/movement sensor. The actuator and the mechanical transmission are contemporaneously connected to the setting mechanism.

The remote-control device features a servomechanism that transmits the movements of a first control cable or tie rod, which is connected to handgrip or control pedal, to a second cable or tie rod which is connected to an application. The servomechanism features two neutral levers with bodies having a cylindrical sector. The levers are connected, respectively, to the cables or tie rods. This servomechanism features a shaft of a geared motor which is arranged coaxially between two bodies of the levers, features a spiral spring arranged between the two bodies and the shaft, and is tightly wound on the shaft. The spring has opposing ends which face outward and extend between the bodies. The servomechanism further features a transducer which detects the movements of first control cable and actuates an electronic unit which controls the geared motor in such a way that the remote control can be effected electromechanically or, in the event that the electrical components malfunction, mechanically.

In a helm, throttle and directional control system for small craft, a safety device arranged to operate between an actuating member and an actuated member has such members coupled rotatively together by means of mechanical one-way coupling devices wherein a resilient force holds the actuated member constantly biassed to a locked position, and wherein the locking action is released by moving the actuating member against the resilient force, thereby motion can be transferred to the actuated member from the actuating member.
