ABSTRACT:
Apparatus is disclosed for temporarily disconnecting from the steering mechanism of a ship one of a plurality of rudders that is in a jammed condition. Each rudder shaft is connected with the steering mechanism via a piston-cylinder motor that is supplied with pressure fluid via a supply system including at least one one-way valve. A safety valve is provided in the system for de-pressurizing the motor to disconnect the tiller member from the rudder shaft when the rudder is jammed and the pivotal force applied to the rudder by the tiller member causes the pressure fluid in the system to exceed the value determined by the safety valve.
