Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
It is as shown in Figures 1 to 5 the structural schematic diagram of the utility model,
Appended drawing reference therein are as follows: oiling steel pipe 1, flared section 21, screw thread 21a, tooth circle 21b, crimping 22, follows at oil filler 2
The fixed bracket 7 of the electrodeless clip 6, first of endless tube 3, fast interpolating unit 31, annular retaining ring 32, throttle valve 4, refueling hose 5, monaural is fixed
Face 71, the first fixation hole 71a, the second fixed bracket 8, the second fixation hole 8a, third fixed bracket 9, third fixation hole 9a.
As shown in Figures 1 to 5,
A kind of hyposmosis type automobile fuel filler pipe assembly, including oiling steel pipe 1 and oil filler 2, oil filler 2 and oiling steel pipe 1
The overall structure being integrally formed, is connected with the circulation pipe 3 that outer diameter is 8mm, internal diameter is 6.6mm on oil filler 2, in circulation pipe 3
It is provided with the throttle valve 4 that orifice diameter is 2mm, the tail end of circulation pipe 3 is provided with the fast interpolating unit 31 to contract, oil filler 2
It is upper that 1 one end of oiling steel pipe is provided with flared section 21, screw thread 21a compatible with fuel tank cap is provided in the flared section 21；
The tail end of oiling steel pipe 1 is fixedly connected with refueling hose 5, the socket of refueling hose 5 with outside oiling steel pipe 1, and with the electrodeless card of monaural
Hoop 6 is fixed.
Refueling hose 5 is using the Composite rubber material of CPT+NBR+PVC, and CPT: fluoroplastics are a kind of high molecular material, molecule knot
Structure is close, can stop the spilling of hydrocarbon molecules.
Using the electrodeless clip 6 of monaural, keep the connection of refueling hose 5 and oiling steel pipe 1 even closer, its whole circle does not have effectively

It closes, and forms crimping 22 in the turned-out volume in end, matched using the circular arc of crimping 22 and the sealing ring of fuel tank cap, improve sealing
Property.
The effect of circulation pipe 3 be refuel when in fuel tank gas and pressure be transported to out of fuel tank oil filling pipe flaring position
It sets, it is still transported to fuel tank by the negative pressure generated when oil stream is dynamic when oiling, and gas and pressure in fuel tank is made to reach balance；From
And it is smooth to make to refuel, and prevents from jumping rifle.
Circulation pipe 3 inserts needs to meet the fast of the fast interpolating unit 31 in tail portion, and generally using outer diameter for 8mm, internal diameter is 6.6mm's
Metal tube, the large diameter of circulation pipe 3 cause ventilation flow rate big, and big flow will lead to the oil vapour at oil filling pipe flaring can not be complete
Portion enters in fuel tank, it can go to gas in atmosphere from the gap of refueling nozzle and oil filler, discharge when oil filling pipe being caused to refuel
It is not up to standard, it is unqualified, environment is also polluted, therefore throttle valve 4 is set to reduce its flow, to reduce fuel tank in circulation pipe 3
In oil vapour enter at oil filling pipe flaring.But the throttle orifice internal diameter of throttle valve 4 can not be too small, if aperture is too small,
When oiling can from a large amount of air suck oil-feed tank, and the gas output of canister be it is constant, the pressure in such fuel tank can become
Cause greatly to jump rifle.
The oil filling pipe of the utility model can effectively reduce the discharge of hydrocarbon molecules, meet six standard of state.
The most preferred embodiment of the utility model has illustrated, the various change or remodeling made by those of ordinary skill in the art
All without departing from the scope of the utility model.
