PURPOSE:To prevent inferior lubrication in starting and any abnormal wear of a cylinder liner by branching operating air from the route of compressed air supplied under pressure from a high pressure air reservoir in starting for performing a constant oiling per one time just before the starting. CONSTITUTION:When a opening/closing valve 5 is opened to start an engine, compressed air is supplied to a cylinder 7 from a high pressure air reservoir 4 through a starting air main pipe 6. Since, at this time, the compressed air in the starting air main pipe 6 is simultaneously supplied to a power cylinder 3 through a branch pipe 8 and an electromagnetic valve 13, the pinion 2 of an oiling device 15 is driven through the rack 10a of a shaft 10 connected to a piston 9 for supplying cylinder oil to the cylinder 7. And when a projection 14 makes contact with a limit switch 11a due to a stroke of the rack 10a, an electromagnetic valve 12 is opened and the piston 9 is returned by a returning spring 16 and electromagnetic valve 13 is shut off. |
