A pressure control system for stern tube seals includes at least two resilient radial lip-type seal rings held so as to surround a propeller shaft linear. The closest seal ring lip to the propeller is arranged to face outboard and the other adjacent seal rings\lips are arranged to face suitable directions so as to form annular chambers. The aft annular chamber located most closely to the propeller serves as a chamber having a fixed differencial pressure higher than the seawater pressure. The closest seal ring to the propeller is lifted, thereby allowing ...
A pressure control system for stern tube seals including at least two resilient radial lip-type seal rings brought into sliding contact with a propeller shaft liner and a housing member which is secured to a stern frame member of a hull in such a manner as to surround a propeller shaft and adapted to hold said seal rings, the lip of one of said seal rings being disposed most closely to the propeller side and being arranged to face outboard, the lip of a seal ring adjacent to said one seal ring being arranged to face inboard so as to form an aft annular c...
