What component will move along with the ram unit in an electrohydraulic steering system?

In an electrohydraulic steering system, the ram unit is responsible for translating hydraulic pressure into movement. When the hydraulic system activates, the ram unit extends or retracts, and its movement is directly tied to the rudder. As the ram moves, it pushes or pulls the rudder, enabling the vessel to change direction. This direct connection between the ram and the rudder ensures that any movement of the ram translates into an appropriate response from the steering mechanism of the ship.

The steering wheel, while crucial for initiating steering commands, does not move with the ram; instead, it sends a signal to the hydraulic system to operate the ram. The hydraulic fluid serves as the medium through which the pressure is transmitted but does not move independently in conjunction with the ram. The propeller is not related to the steering function at all and is instead part of the propulsion system. Therefore, the rudder is the component that moves in direct response to the ram's action in an electrohydraulic steering system.
