ABSTRACT:
In a pressurized-fluid operated steering gear system for a ship of the kind in which a plurality of actuators (piston-and-cylinder or rotary vane) are disposed in opposed pairs to turn the tiller arm when a diametrically opposed pair is pressurized and the other diametrically opposed pair is relieved of pressure the improvement that there is located in the cylinder, or arcuate chamber, of each actuator a free moving member which separates two distinct pressurized fluid inlets of said cylinder or chamber. If there is no pressure delivery from one inlet the member moves to one end of the cylinder or chamber so that the actuator is worked by pressure solely from the other inlet.
