LINEAR DRIVE FOR AUTOPILOT
For the MARSILI encoding they are called “systems type B” (same category of the electrohydraulic steering systems).
The MARSILI autopilot steering systems meet perfectly the needs of motorized and sailing vessels of all types from nautical to working ones and/or with a mechanical steering system already installed.
Very simple to install and built with materials which are resistant to the maritime environment.
Usually, the steering systems for autopilot are made up of one or more hydraulic cylinders, an electric bypass and one or more power packs.
The hydraulic cylinder is fixed on the sector of the mechanical steering system already installed.
The electric bypass is necessary to bypass the hydraulic system when the vessel is manoeuvred by the mechanical system.
A large range of electric bypasses, hydraulic cylinders, electrohydraulic power packs with voltage on demand and accessories, allow a precise choice of the most suitable equipment for all necessities, the reliability and comfort are guaranteed.
The MARSILI steering systems for autopilot are designed with an accurate attention to details, during the phases of production and test, aiming to obtain systems with high manoeuvrability, trying not to affect the normal handling of the mechanical steering system.
The MARSILI power packs are adaptable to all kinds of autopilots.
The standard directional valves are 12V or 24V ON-OFF, but proportional directional valves can be supplied as well.
The power packs of the systems Type “B” are classified as “Y” or “W”.
The power packs type “Y” exploit the power of an electric motor coupled to a gear pump, the tank and the base of the electric motor are complete of control and safety valves and filters; the movement of the rudder is obtained by means of a solenoid valve controlled by an electric transmitter on the bridge.
The power packs type “W” exploit the power of a gear pump coupled to a motor on board or to a belt driven support which transmits the rotation and, thus, the oil flow to the valve group installed on the tank.
