Abstract
The utility model relates to an improvement on a fuel tank. The upper surface of the fuel tank is provided with a pressure balancing device (air inlet valve and vent valve) to lead the fuel tank to supplement pressure to the continuously appeared negative pressure in the fuel tank when the fuel tank is used normally, always keeps the fuel tank to be under a normal working pressure state and limits the vaporation of fuel. The environment-protective fuel tank can lead the fuel to be under a normal working state all the time and can also limit the pollution to air caused by fuel vaporizing, and save a certain amount of fuel as well.
Description
The utility model relates to the improvement to a kind of fuel tank
Common fuel tank of vehicle is not environmental protection, because fuel tank normal fuel injection, fuel tank be can not leak free (pasta decline can cause negative pressure, influence fuel feeding), and the fuel tank blowing-by, the evaporation of fuel oil can cause environmental pollution again, so common fuel tank all is to leave air extractor vent, this just pollutes atmosphere, and fuel oil also has certain waste.
The purpose of this utility model is to provide a kind of can control fuel oil evaporation, can make fuel tank not cause the pressure equaliser of negative pressure energy normal fuel injection again, promptly end often, the evaporation of restriction fuel tank keeps the seal isolation state with atmosphere, when pasta decline causes negative pressure in the fuel tank, balancing device is opened, atmosphere enters supplementary pressure in the fuel tank, makes in the fuel tank to keep balance with atmosphere, and can guarantee normal fuel injection.
1 the utility model is to realize so in conjunction with the accompanying drawings.When automotive operation, the oil suction pipe 2 of fuel tank 1 is with fuel oil 3 sucking-offs, 3 declines of fuel oil, produce negative pressure in the fuel tank 1, at this moment the pressure equaliser (air inlet valve) 4 of fuel tank 1 upper surface is opened, make fuel tank 1 internal pressure balance, when pressure equaliser (air outlet valve) 4 is closed, the evaporation of fuel oil 3 will be limited and keep normal pressure.
According to the environmental protection fuel oil case that said structure is made, make the normal while of automobile fuel feeding, also environment is protected, and can be saved certain fuel oil.
Description of drawings:
Fig. 1, environmental protection fuel oil case scheme drawing
Embodiment: according to structure shown in the accompanying drawing, pressure equaliser can be installed at the upper surface of various fuel tanks, fuel tank and pressure equaliser have through hole, and pressure equaliser can be also plastics of metallo-, and it is definite that air inlet and exhaust gas pressure press the fuel tank structure.
Claims (1)
1, a kind of environmental protection fuel oil case is characterized in that at the upper surface of fuel tank (1) pressure equaliser (inlet and outlet valve) (4) that can make the balance that keep-ups pressure in the fuel tank (1) being installed.
