Abstract
An automatic opening and closing device for a vehicle lubrication flow passage includes a valve housing installed on one side of an oil pump of the vehicle and includes a valve positioned in the valve housing and installed in a lubrication flow passage of the oil pump that passes through the inside of the valve housing. The valve is operated to open and close the lubrication flow passage by rotation. The device also has a mass member installed on one end of the valve to surround a rotation axis of the valve. The mass member is rotated by an inertial force generated during a turn or acceleration/deceleration of the vehicle to rotate the valve.
