Title:
LUBRICATION OIL SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2017089489
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lubrication oil supply device exhibiting an energy-saving effect even if the revolving speed of a pump increases.SOLUTION: By a multistep on-off valve mechanism, in a revolving speed of an internal combustion engine, a discharge pressure is stabilized between a second speed and a third speed, and at or over a fifth speed.EFFECT: The portions, as indicated by triangles, of an area (e) and an area (f), become an energy saving contribution. In short, there is provided a lubrication oil supply device by which an energy saving effect is exhibited even if the revolving speed of a pump increases.SELECTED DRAWING: Figure 12
