Abstract: Disclosed is a trochoid lubricant supply device that is configured to connect to a rotational shaft. A connector of the lubricant supply device is configured to reduce an oil leakage amount of lubricant, and is configured to insert to a lower portion of a rotational shaft. The connector includes: a rotator mounting member inserted into and fixed to the rotator of the lubricant supply device; a penetrating member that penetrates a fixer of the lubricant supply device; an enlarged diameter extending radially outwards from the penetrating member outside the fixer; and a rotational shaft mounting member extending axially in the diameter enlarged member and is fastened to the rotational shaft. Further, the lubricant supply device of the present disclosure can supply the oil regardless of a rotation direction of the rotational shaft by supplying the oil by a space pivoting about the rotational center of the rotator.

Abstract: A lubricating oil supply apparatus having a structure in which a valve is forced in a direction for opening a bypass hole by a centrifugal force, and a spring presses the valve in a direction in which the valve closes the bypass hole. When the above-described structure is applied to an oil pump in which an oil (lubricating oil) supply amount increases in proportion to an operation speed, it is possible to secure a sufficient oil (lubricating oil) supply amount in a low speed operation mode, and prevent oil from being supplied more than necessary in a high speed operation mode.
