機関の潤滑オイル供給装置。[Claims for Utility Model Registration] An oil tank that stores lubricating oil, an oil pump that pumps out the lubricating oil from the oil tank through an oil conduit, and an oil pump disposed downstream of the oil pump in the oil conduit. an oil check valve that prevents the lubricating oil from flowing back toward the oil pump; and an oil check valve that is disposed downstream of the oil check valve in the oil conduit so that the lubricating oil is present in the oil conduit. and an oil presence/absence detector for detecting whether or not the lubricating oil is pumped out from the oil tank, and the lubricating oil pumped from the oil tank is supplied into an intake manifold communicating with the inside of the crankcase through the oil conduit. In the lubricating oil supply device for a separate oil supply type two-stroke engine, the oil presence/absence detector includes a transparent tube that forms a part of the oil guide, a light emitter that emits light into the transparent tube, and a light source that emits light into the transparent tube. It is possible to determine whether or not the lubricating oil is present in the transparent tube by utilizing a phenomenon in which there is a difference in the refractive index of light passing through the transparent tube depending on whether the lubricating oil is present or not. and a light receiving body that receives light from the light emitter in either case, and the oil guide path between the oil check valve and the oil presence/absence detector is connected to the inside of the crankcase. The lubricating oil is communicated through a fuel return conduit, and a lubricating oil is provided in the middle of the fuel return conduit to prevent the lubricating oil from entering the crankcase through the fuel return conduit. A lubricating oil supply device for a two-stroke engine with separate oil supply, characterized in that a fuel check valve is disposed to prevent mist fuel from flowing back into the crankcase.
