Claims

[Scope of Claim for Utility Model Registration] A separate external oil tank is provided outside the engine body, and lubricating oil is transferred from the oil pan at the bottom of the crank chamber to the external oil tank and stored therein. In a lubrication system that leads lubricating oil from an external oil tank to an engine oil supply pump and circulates it to each part of the engine, the above-mentioned discharge-side oil is placed in the middle of the lubricating oil discharge-side oil path that communicates from the suction pump to the external oil tank. a cylindrical pipe having a diameter larger than that of the pipe and a predetermined length; a fixed wing installed on the upstream side of the pipe; and an opening having a smaller diameter than the pipe on the downstream axis center line of the pipe. A gas-liquid separator is installed, comprising a bubble passage facing the air bubble passage, and an oil passage communicating with the external oil tank from the outlet side of the pipe line, and the gas-liquid separator is located downstream of the bubble passage. of,
A lubricating oil bubble separation device, characterized in that the device communicates with the upper space of the external oil tank.
