用内燃機関の潤滑装置。 A bypass passage that branches from the upstream side of the oil cooler and connects to the downstream side is provided in the passage that supplies oil under pressure from the oil pump to various parts of the engine via the oil cooler. In a vehicle internal combustion engine lubricating system equipped with a thermo-valve that opens and closes the downstream side of the oil cooler, and closes a bypass passage and opens the downstream side of the oil cooler when the temperature is high, the inlet of the thermo-valve and the oil cooler are connected to each other. A sub-bypass passage is provided that connects the lubricating oil passage to the oil cooler upstream by bypassing each of these valves, and also bypassing the thermovalve outlet from the downstream side of the oil cooler. A sub-bypass passage is provided, and this downstream sub-bypass passage and a valve are provided, and based on the signals from the means for detecting the engine cooling water temperature and the means for detecting the engine speed, when the cooling water is low temperature below a set value, A lubricating device for an internal combustion engine for a vehicle, comprising a control means that closes the two valves on the upstream side and opens the valve on the downstream side when the engine speed is low and is equal to or lower than a set value.
