Abstract
Description
An embodiment of the present invention relates to an air circulation type air breather of an oil tank for a vehicle.
Generally, an air breather mounted on an oil tank for a transmission of a vehicle raises the plate upward when the internal pressure of the transmission rises, thereby discharging the internal air through a gap between the body and the plate. Further, when the internal air is discharged and the pressure is held constant, the plate is lowered by the force of the spring and then blocked again.
Thus, in the conventional air breather, there is only an effect of discharging the internal air when the internal pressure of the transmission rises.
In addition, the conventional air breather has a problem of leakage due to the occurrence of deviation of the air breather during running of the vehicle due to the press-fitting of the hole in assembling the housing of the transmission.
In addition, the conventional air breather has a problem in that the pressure rises and the internal oil leaks when the air is discharged.
In addition, the conventional air breather only discharges the internal air, and there is a problem that the external air can not be sucked.
