PURPOSE:To make lubricating oil feedable without fail even if any of individual discharge ports of a lubricating oil pump is blocked up, by interconnecting all discharge ports of the lubricating oil pump to a single distribution chamber, and also interconnecting the distribution chamber and lubricating oil feed parts of each cylinder through by means of each distributing pipe. CONSTITUTION:A lubricating oil pump 20 sucks up lubricating oil inside a tank 19 and is fed to a distribution chamber 37 from each of discharge ports 22A- 22C by way of a collection chamber 35 and a main pipe 36, while further fed to each cylinder from feed ports 41-43 of each carburetor 18 by way of distributing ports 37A-37C and distributing pipes 38-40. And, even in case a closure happens due to the admixture of foreign substances of the like into the setup part of a check valve belonging to any of individual discharge ports 22A- 22C, the discharge of lubricating oil into the collection chamber 35 from other discharge ports where no closure happens is continued to discharge out, so that the lubricating oil is surely fed to each cylinder. |
