Description
technical field [0001] The invention relates to the field of fuel tank caps, in particular to a fuel tank cap capable of both sealing and breathing air in and out. Background technique [0002] The fuel tank, that is, the fuel storage device, under the double working pressure, the overpressure generated must be decompressed by itself through the hole or the safety valve. The traditional fuel tank cap is usually used to seal the fuel tank to avoid oil leakage, but when the fuel tank When the amount of oil decreases with use, the air pressure in the fuel tank drops, and it is impossible to take in air through the tank cover, causing the air pressure in the fuel tank to drop all the time, causing damage to the fuel tank. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a fuel tank cap capable of both sealing and breathing air in and out, which has the advantages of both seali...
