Abstract

PURPOSE:To obtain an alarm system which is high in its reliability and easy in its assembly in such a way that abnormal low oil pressure is detected by a mechanical means which is assembled in the lubricating oil circuit. CONSTITUTION:When the engine is started, and a marine gear has power transmitted, an oil pump 6 is operated, oil pressure is produced, and proper oil pressure is formed respectively on the upstream side of a change-over valve 3 in a clutch oil pressure circuit 8 and in a lubricating oil circuit 11 by means of a clutch oil pressure regulating valve 10 and a lubricating oil pressure regulating valve 12. If such an abnormality as oil leak or another occurs, and if lubricating oil pressure is lowered, even though oil pressure in a pipeline 16 is slowly lowered by means of a damper 21 and a variable flow valve 20, because there is no subsequent oil pressure rise, pressure in the pipeline 16 continues to be on the decline, and finally it goes down until it gets to the determined pressure to close an oil pressure switch 17, and it actuates the alarm device.
