<p>Steering apparatus for steering a substantially cylindrical body, especially for steering the rudder post (1; 101) on a ship, comprising an actuator (2; 102) having a rotor member (3; 103) attached to the rudder post (1; 101) and one in relation to the rudder post (1; 101) stationary house member (4; 104), said rotor member (3; 103) being provided with vanes (4a, 4b; 104a, 104b) which in the actuator (2; 102) define pressure chambers (105a) which are connected to steering power units (8a; 108a), which steering apparatus for the object of providing a safer operation of the apparatus at the same time as the apparatus can be manufactured by means of simple basic elements and a simple machining thereof, and at the same time as the apparatus can be inspected and maintained more rationally, is characterized in that the actuator (102) comprises at least two pressure chambers (105a, 205a) or at least two sets of pressure chambers (105a, 106a respectively 205a, 205b) which are operated by their own individual independent power unit.</p> |
