ENGINE OIL SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device capable of supplying oil to each structural element of an engine efficiently as needed without complicating device configuration and a jump of manufacturing cost. SOLUTION: In an oil supply device 1, a first oil passage 21 transporting oil discharged from a mechanical oil pump 2 and a second oil passage 22 transporting oil discharged from an electrical oil pump 3 are connected to collecting passage 23 at a part (connection point) P corresponding to each downstream side opening end. A check valve 22a allowing oil flow from the second oil pump 3 toward the connection point P while regulating reverse flow is provided in the second oil passage in downstream of the second oil pump 3. A branching passage 25 is connected to a designated part (connection point) R between the oil pump 3 in the second oil passage 22 and the check valve 22a. The branching passage 25 is a passage for transporting oil to the structural elements of the engine and is provided with an orifice 25a in the middle of the passage. COPYRIGHT: (C)2004,JPO&NCIPI
