Abstract (en)
Described is a ship propulsion system (1) comprising a propeller arrangement (2) having at least one adjustable propeller blade (3) connected to a hub (6) housing a hydraulic cylinder arrangement comprising a first pressure chamber (7) and a second pressure chamber (8) separated by a piston (9) connected to and operating an regulating device for the at least one adjustable propeller blade (3) and a propeller shaft (5) located between the hub (6) and a torque transmission unit (4) where the propeller shaft (5) comprises a valve arrangement (10) provided with fluid from a hydraulic power unit (11) and having a number of valve fluid channels (17,18,19,20) connected to a number of check valves (15,16) for controlling a flow of fluid through a first duct (13) and a second duct (14) to the first pressure chamber (7) and from the second pressure chamber (7), respectively, or vice versa. The ship propulsion system is characterized in that the valve arrangement (10) comprises at least one check valve (15,16) arranged in a valve housing (12) being mounted to an outside surface of the propeller shaft (5) and rotating together with the propeller shaft (5).
