Abstract
The invention relates to an oil way control method and a control device thereof. A distributor shaft is installed in a center hole of a distributor body. An electromagnetic valve hole is machined in the upper portion of the distributor body. An electromagnetic valve is assembled in the electromagnetic valve hole. Vertical oil channels and a horizontal oil channel are machined right above the center hole. The vertical oil channels and the horizontal oil channel are through. An oil plug is arranged on an outlet of each vertical oil channel. An inner oil channel is machined in the center of the distributor shaft. An oil input ring groove and an oil drainage ring groove are formed in the periphery of the distributor shaft. An oil input groove and an oil drainage groove between which a certain angle is formed are formed in the axial direction of the distributor shaft.
