Opening/closing of described control setup 15 described first breather pipes 21 of control and described equalizing pipe is specially:
Described control setup 15 described first breather pipes 21 of control and described equalizing pipe are open-minded after fuel up finishes.
Need to prove, in various embodiments of the present invention, described main fuel reservoir 11 is the different of title with described primary fuel case 12, be relative rather than specific, fuel tank as left side among Fig. 2 can be that primary fuel case 12 also can be a main fuel reservoir 11, the fuel tank in left side can be that main fuel reservoir 11 also can be a primary fuel case 12, also is that main fuel reservoir 11 and the primary fuel case 12 in the various embodiments of the present invention can transform mutually.
In a preferred embodiment of the invention, described equalizing pipe 16 stretches into from the top of described main fuel reservoir 11, be that described equalizing pipe 16 directly gos deep in the main fuel reservoir 11 from the top of main fuel reservoir 11, and go deep into the mouth of pipe that pipe ranges in the main fuel reservoir 11 need guarantee that high liquid level pasta still can enclosed balance pipe 16 when tilting, thereby guarantee the air-tight state of primary fuel case 12, therefore, preferably described equalizing pipe 16 pipe range that stretches into described main fuel reservoir 11 is not less than half of described main fuel reservoir 11 height.
In another preferred embodiment of the present invention, described equalizing pipe 16 is arranged on the position that is not more than half height on the described main fuel reservoir 11 apart from described main fuel reservoir 11 bottom surfaces with the junction of described main fuel reservoir 11.Definite mode of equalizing pipe 16 mouth of pipe height and positions can be provided with about the standard of the tilt quantity of travelling of construction machinery and equipment according to country, therefore, still can seal the mouth of pipe of the equalizing pipe 16 on the main fuel reservoir 11 when guaranteeing high liquid level pasta with inclination of vehicle, therefore preferably equalizing pipe 16 open ends are arranged in main fuel reservoir 11 is not more than 50% height apart from the bottom surface position.Certainly, the junction of described equalizing pipe 16 and described main fuel reservoir 11 also can be arranged on the described main fuel reservoir 11 position apart from half height of described main fuel reservoir 11 bottom surfaces.
Further, also can be provided with the oil return pipe interface 18 that is communicated with oil return pipe on the described main fuel reservoir 11.
Further, also be provided with the pressure balance valve 20 that is used to regulate main fuel reservoir 11 internal gas pressure differences on the described main fuel reservoir 11.Described pressure balance valve 20 plays the effect of regulating main fuel reservoir 11 internal gas pressure differences, stablizes the external and internal pressure in the fuel tank.
In addition, the oil filling port 17 of described main fuel reservoir 11 also is provided with fuel lid.
In another preferred embodiment of the present invention, described fuel tank structure also comprises linkage, described linkage is arranged between described control setup and the described fuel lid, is used for controlling described control setup when described fuel lid On/Off and opens/close described first breather pipe 21 and described second breather pipe 22 synchronously.
The effect of described linkage is to guarantee described fuel lid and described triple valve unlatching and close synchronously synchronously, during oiling, need to open the triple valve valve earlier and be communicated with breather pipe 14, the air of discharging in the primary fuel case 12 in the fuel up process is removed the air pressure resistance in the primary fuel case 12 in breather pipe 14 is discharged to main fuel reservoir 11.After filling with fuel oil, to close the triple valve valve when covering fuel lid and block breather pipe 14, and open the pipeline of breather pipe 14 and equalizing pipe 16, make primary fuel case 12 and main fuel reservoir 11 warp " oil pipe 13-triple valve-equalizing pipe 16 " pipeline connections, thereby in the process of moving, when vehicle body is tilted to the right, the pasta of right side main fuel reservoir 11 will rise, near or exceed the connected entrance of fuel lid and air, and the liquid level in the offside tank will descend, form a negative pressure space at the fuel tank top, barometric pressure will press the right side pasta to descend, and can avoid fuel oil to overflow by actv.; When vehicle body was tilted to the left, left side primary fuel case 12 upper end closeds, the fuel level of rising increased the space internal gas pressure on its top, and the pressure difference of formation can be controlled the level change in the fuel tank, thereby avoids fuel overflow.
The triple valve on the described breather pipe 14 and the distance of described main fuel reservoir 11 are less than a predetermined threshold value, described predetermined threshold value can be confirmed with actual conditions according to the actual requirements, the present invention does not limit this, in a preferred embodiment of the invention, when described predetermined threshold value takes a certain less numerical value (as 1CM, 0.5CM ...) time, the triple valve on the described breather pipe 14 is near described main fuel reservoir 11.
Working process and principle of work to fuel tank structure of the present invention is described in detail below.
Fuel tank structure of the present invention adopts major and minor fuel tank 12 arrangements, at the place, bottom oil pipe 13 being set is communicated with primary fuel case 12 with main fuel reservoir 11, the top of major and minor fuel tank 12 is provided with breather pipe 14 and links to each other, near a triple valve is installed on the breather pipe 14 of main fuel reservoir 11 1 ends, connect two sections breather pipes 14 and equalizing pipe 16 respectively.Oil filling port 17 is set on the main fuel reservoir 11 and fuel lid is installed.When fuel up in fuel tank, triple valve and fuel lid need be opened simultaneously, avoid stoping fuel oil to enter in the primary fuel case 12 because air compression forms high pressure air in the primary fuel case 12.
In the fuel feeding process, fuel oil is through the combustion chamber of oil out port 19 along the pipeline flow direction engine, the fuel oil pressure release of partial reflux after oil return line flow back in the main fuel reservoir 11 from the oil return pipe interface 18 on the main fuel reservoir 11, also comprise a spot of air with what oil return entered main fuel reservoir 11, pressure balance valve 20 on the main fuel reservoir 11 plays the effect of regulating main fuel reservoir 11 internal gas pressure differences, stablizes the external and internal pressure in the fuel tank.In whole fuel feeding process, because the effect of air pressure, oil level in the main fuel reservoir 11 descends will be prior to primary fuel case 12, when the liquid level in the main fuel reservoir 11 drops to equalizing pipe 16 mouths of pipe when following, primary fuel case 12 will be communicated with atmosphere by equalizing pipe 16, thereby can not occur in whole process because the influence of draught head causes the phenomenon of fuel feeding difficulty to occur.
The oil filling port of technical solution of the present invention cancellation primary fuel case only is provided with oil filling port separately, and major and minor fuel tank is connected in the upper end with breather pipe, thereby increases the fuel tank seal area on main fuel reservoir, reduce and leak origination point; Further, described breather pipe is provided with triple valve, and the other end of described triple valve is connected with described main fuel reservoir by equalizing pipe, utilizes the draught head principle, can eliminate the generation of fuel tank overflow phenomena to greatest extent.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
