Abstract
PURPOSE: To ensure safety of a ship when the ship is propelled, by such means that to prevent a propeller from damage due to an obstacle the propeller is swung upward and then automatically suwung again downward.
CONSTITUTION: A reversible liquid pressure pump 8 driven by a reversible motor 7 press feeds liquid to a pipe line 10 for its forward rotation while to a pipe line 9 for its reverse ratation. The pipe lines 9, 10 are connected to a reservoir 12 through check valves 11, 15 further the pipe line 9 is connected to the reservoir 12 through a relief valve 13. A port 14c of a selector valve 14 is connected by a pipe line 16 to a contraction side liquid pressure chamber 6c in a liquid pressure cylinder 6 while a port 14d is connected to an extension side liquid pressure chamber 6d in the cylinder. A resetting valve 19 is a valve for swinging a propeller downward after swinging the propeller upward, and a piston valve 20 is provided with a valve spool 20b, in this way high pressure liquid in the resetting valve can be relieved to the reservoir 12.
