Description
Technical field
The utility model relates to automobile refuelling pipe technical field, particularly relates to a kind of fueling system.
Background technology
Due to vapour oil volatility, automobile is in refueling process, in working process or because of ambient temperature increase, fluid evaporation in fuel tank, fuel tank internal vapor pressure increases, fuel tank dilatational strain, when fuel tank pressure reaches weight valve response pressure, in fuel tank, steam directly enters canister and is adsorbed.Thus fuel tank needs certain vapor space to avoid fuel tank bad because crushing in excessive for storing oil vapour, causes safety misadventure.
Need the reserved vapor space being not less than 10% volume in general fuel tank design process, to be used for the fuel-steam in buffer memory fuel tank without expansion chamber because of fuel filler pipe, fuel tank needs larger arrangement space, meets nominal volume and vapor space requirement.Usual fuel tank limits because of arrangement space, limited volume, the vapor space can not meet 10% volume requirement, now often needs to sacrifice fuel tank nominal volume to increase the safety that the vapor space ensures fuel tank, cause fuel tank nominal volume not enough thus, automobile course continuation mileage shortens.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of fueling system, can solve fuel tank because of arrangement space to limit, and the vapor space is not enough, problem that the fuel tank nominal volume caused is not enough.
In order to solve the problems of the technologies described above, the utility model provides a kind of fueling system, and it comprises the expansion chamber and filler pipe that are connected with fuel tank, and described expansion chamber and filler pipe are integral type structure, and described expansion chamber is connected with filler pipe.
Preferably, described expansion chamber and filler pipe integrally blow shaping.
As the improvement of technique scheme, described expansion chamber is provided with weight valve, and described weight valve is connected with canister by the first steam pipe.
As the improvement of technique scheme, described expansion chamber is provided with fast plug, and described fast plug is connected with fuel tank by the second steam pipe.
Preferably, described fast plug is at least provided with 1.
Preferably, described expansion chamber is positioned at the top of fuel tank, and described fast plug is arranged on the bottom of described expansion chamber.
As the improvement of technique scheme, described filler pipe is connected with breather pipe.
Preferably, described breather pipe be connected to described filler pipe oil inlet side tube wall on and be connected with described filler pipe.
Preferably, described first steam pipe, the second steam pipe and breather pipe are flexible pipe.
Implement a kind of fueling system of the present utility model, compared with prior art, there is following beneficial effect:
The utility model is by above-mentioned expansion chamber and filler pipe integrally blow molded design, make use of the space of filler pipe fully, filler pipe is made to have effect for the fuel-steam in buffer memory fuel tank, when in automobile fuel filler process or in working process or ambient temperature raise, the some vapor storage space of fuel tank can be transferred in expansion chamber and filler pipe, add the volume of fuel tank; Save the arrangement space of fuel tank, the not enough problem of nominal volume that fuel tank causes because arrangement space limits can have been solved; Can avoid designing separately the arrangement space waste that expansion chamber causes, part management difficulty and cost increase problem simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described to the accompanying drawing of embodiment below.
Fig. 1 is the structural representation of a kind of fueling system of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, an embodiment of the present utility model, a kind of fueling system, it comprises the expansion chamber 1 and filler pipe 2 that are connected with fuel tank, and described expansion chamber 1 is integral type structure with filler pipe 2, and described expansion chamber 1 is connected with filler pipe 2.Visible, the present embodiment is by above-mentioned expansion chamber 1 and filler pipe 2 unitary design, make use of the space of filler pipe 2 fully, filler pipe 2 is made to have effect for the fuel-steam in buffer memory fuel tank, when in automobile fuel filler process or in working process or ambient temperature raise, the some vapor storage space of fuel tank can be transferred in loading system (i.e. expansion chamber 1 and filler pipe 2), add the volume of fuel tank; Save the arrangement space of fuel tank, fuel tank can have been solved and limit because of arrangement space, problem that the volume caused is not enough; Can avoid designing separately the arrangement space waste that expansion chamber 1 causes, part management difficulty and cost increase problem simultaneously.
Preferably, described expansion chamber 1 adopts plastic material integrally blow shaping with filler pipe 2, low cost of manufacture.
In order to realize the control of gasoline vapor pressure in expansion chamber 1, described expansion chamber 1 is provided with weight valve 11, and described weight valve 11 is connected with canister by the first steam pipe 3.Thus, when the gasoline vapor pressure in expansion chamber 1 reaches the response pressure of weight valve 11, gasoline vapor enters canister by the first steam pipe 3 and is adsorbed, and is finally entered driving engine by desorption and burns.
Conveniently assemble, described expansion chamber 1 is provided with fast plug 12, and described fast plug 12 is connected with fuel tank by the second steam pipe.Like this, when in automobile fuel filler process or in working process or ambient temperature raise, the gasoline vapor in fuel tank is entered in expansion chamber 1 by the second steam pipe be connected with the quick connector on expansion chamber 1 and stores.
Preferably, described fast plug 12 is at least provided with 1, to ensure that the steam in fuel tank can enter expansion chamber 1 smoothly, avoids because of fuel oil expanded by heating excessive velocities, pressure release is not enough and cause in fuel tank and press through large problem.
Preferably, described expansion chamber 1 is positioned at the top of fuel tank, and described fast plug 12 is arranged on the bottom of described expansion chamber 1.Like this, expansion chamber 1 and fuel tank are that high-low-position is arranged, the fuel oil in expansion chamber 1 can be entered in refueling process from filler pipe 2, flow in fuel tank voluntarily under gravity, effectively preventing from causing the steam storage space in expansion chamber 1 to reduce because hoarding fuel oil in expansion chamber 1.
On the basis of above-described embodiment, described filler pipe 2 is also connected with breather pipe 4.Concrete, the tube wall that described breather pipe 4 is connected to described filler pipe 2 oil inlet side is connected with described filler pipe 2.It should be noted that, the oiling exhaust pathway (fuel tank → canister → driving engine) of vehicle-mounted oil filling gas recovery system for oil is different from non-vehicle-mounted oil filling gas recovery system for oil, in the refueling process of vehicle-mounted oil filling gas recovery system for oil, in fuel tank, steam does not allow to enter air through filler pipe 2 but need to enter canister to be adsorbed.Therefore, can not need to set up breather pipe in vehicle-mounted oil filling gas recovery system for oil.
Described first steam pipe 3, second steam pipe and breather pipe 4 are all preferably flexible pipe.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
