Abstract
PURPOSE: To prevent masker bubbles from invading into a sea chest and improve propelling performance on a rapid voyage, by providing an extended/retracted sea water suction cylinder in the sea chest.
CONSTITUTION: A sea water suction cylinder 1 is guided by a bearing 4 which is secured in a sea chest so that the cylinder 3 is fitted in the circular hole of the bottom of the sea chest 2. As a result, the sea water suction cylinder 1 can be moved up and down. The cylinder 1 has an upper and a lower openings. A shaft 5 is fixed on the cylinder 1. The shaft 5 is supported by a bearing 7. The piston rod 9a of a hydraulic cylinder 9 installed in a hull is coupled to the upper end of the shaft 5.
