Abstract
The mechanical breather valve includes a valve body, on which is installed one-way air inlet and outlet components. A tank, for environmental protection, is fitted with the breather valve and closed so that no volatile gas will be exhausted, when the pressure within is balanced with the outside. When the pressure within is negative, the one-way air inlet hole will draw air from outside to keep the balance of pressure. When the pressure within is increased, one-way air outlet hole will exhaust the additional air. When the tank is tilted or placed upside down, the breather valve can prevent the oil from flowing out of the tank for safe usage.
