Abstract

PURPOSE:To aim at improvement in fuel consumption, etc., by providing a relief valve, which is opened at the time of a light load, on the way of the lubricating oil passage on the upper stream side from the bearing metal of an engine and connecting takeoff passages for supplying lubricating oil to accessories on the way of the lubricating oil on its upper stream side. CONSTITUTION:In a lubricating device in which a main lubricating oil passage 12 serving as the discharge side pipe of an oil pump 7 driven by an engine is connected to the lubricated parts such as the inside of a rotor, etc., a branch portion 17 is connected on the way of the main lubricating oil passage 12 and a rotary valve 18 serving as a relief valve opened at the time of an light load of the engine is connected to the branch portion 17. This rotary valve 18 is constructed in such a way that a cylindrical valve body 23 is slidably arranged in the hole portion 22 of a housing 19 and the communicating area between a through hole 25 and a port 24 is changeable by the operation of an actuator 28. Further, takeoff passages 40, 41 for supplying lubricating oil to a supercharger 38 and an oil pump 39 are connected on the way of the lubricating oil passage 12 on the upper stream side of the valve 18.
