Background technology
Traditionally, have the petrolift that is arranged in the Fuel Tank and filter, the formula fuel supply system generally is used for motor bike and automobile in the so-called case.
The formula fuel supply system comprises the secondary Fuel Tank that is arranged in the Fuel Tank in the many this so-called case on motor bike and the automobile, this pair Fuel Tank is used for preventing any possible interruption in the fuel feeding, and this interruption results from motor bike or automobile climbing or when being vibrated.In this device, usually, box-like or shell-like container is set to the secondary Fuel Tank in the Fuel Tank, petrolift is suitable for draws fuel from secondary Fuel Tank, therefore, if the run-off the straight when motion of motor bike or automobile, but fuel suction port can not exposed the fuel in this case and be exposed in the air.With regard to this layout, even when motor bike or automobile generation vibration, also can come fueling with stable benchmark.
But during the driving engine, the motor bike and the automobile that are provided with this fuel supply system have been extended tilting a period at fuel feeding.In particular, when being in heeling condition, motor bike usually is forced to support (prance) on the trailing wheel or lean against on the support of sidepiece, and fuel has to supply on the driving engine continuously simultaneously.In this case, find that the fuel inlet port is very low, although be provided with secondary Fuel Tank, fuel has flowed out by the there, thus make with stablize benchmark in the period that prolongs to driving engine fueling possibility no longer.
Simultaneously, in the formula device, one or more filter element such as paper filter and/or artificial resin filter are contained in the filter in case, thereby filter the fuel of discharging from petrolift.But, be easy to generate static owing to produce friction with filter material by the fuel of filter.In addition, by before the filter and afterwards, this fuel has increased eddy current, thereby produces friction between artificial resin housing and fuel, so this has also produced static.
The real interior formula fuel pump apparatus of clear No.8-232792 proposition case of opening of Japanese patent application, wherein, earth lead is connected in the fuel filter, thereby the static that is produced is flow on the ground.Lead is connected on each part that is installed in the case.Then, lead is electrically connected with the wiring system of self-propelled vehicle, thus these part ground connection and prevent the charging.

Simultaneously, the Fuel Tank operated by rotary motion has the warning sensor with thermally dependent resistor, when the fuel in the Fuel Tank drops to less than a certain limit range, in this thermally dependent resistor driver Fuel Tank left fuel quantity.Generally, electricity is crossed this thermally dependent resistor with very little data rate stream, so the heat that thermally dependent resistor produced is very little.When Fuel Tank is filled fuel and thermally dependent resistor when immersing in the fuel, fuel cooling thermally dependent resistor, so its temperature can not raise.On the other hand, make thermally dependent resistor expose fuel if fuel quantity drops to, fuel no longer cools off it so, and its temperature will raise.
The resistance of thermally dependent resistor is along with its temperature changes.Therefore, the fuel quantity that remains in Fuel Tank can detect by the resistance variations of surveying thermally dependent resistor.Therefore, thermally dependent resistor is generally as the sensor.Then, the lead that is connected on the thermally dependent resistor also is arranged in the Fuel Tank, therefore accept by means of lead from the signal of thermally dependent resistor, thereby detect in the Fuel Tank left fuel quantity.
But, in petrolift, had been found that many other leads, comprising prevent filter electrically-charged these and to these of motor power supply.Therefore, when being provided with lead for thermally dependent resistor, if the lead on the minus side is put together, the number of conductors in the Fuel Tank will be huge so.This just means that structure thermally dependent resistor certainty is with increase, the increase of number of parts and the increase of manufacturing expense of the workload of circuit working.

The specific embodiment
Now, with reference to the accompanying drawing that illustrates the preferred embodiment of the present invention the present invention is described.Fig. 1 is the schematic side elevation that is arranged in the embodiment of on the appropriate location, fuel supply system of the present invention.Fig. 2 is the exploded perspective schematic view of the embodiment of fuel supply system of the present invention.Fig. 3 is the schematic side elevation of the embodiment of fuel supply system of the present invention, and it is that the mode of cross-sectional plane is carried out diagram with the part.Fig. 4 is the schematic plan view of the embodiment of fuel supply system of the present invention.
The fuel supply system 1 of this embodiment (hereinafter being called " device " simply) is suitable for carrying out work as formula (in-tank type) gas supply device in the case that motor bike uses.As shown in Figure 1, device 1 is installed in the opening 3, and opening 3 forms by the bottom 2a that passes Fuel Tank 2 from the bottom.Shown in Fig. 2 and 3, it comprises cup-shaped member matrix 4, and matrix 4 has petrolift 5, filter 6 and pressure regulator 7 and other element, thereby forms the module pattern.The fuel 42 that device 1 comes self-fractionating pump 5 to be drawn by means of filter 6, and fuel feed pipe 43 fuel feeding before the driving engine, pressure regulator 7 is adjusted to predetermined value to fuel pressure.
Chassis on the bottom of flange 4a formation element body 4.Flange 4a and container 4b form one, and container 4b is used as sidewall, and this sidewall forms by artificial resin is molded.When device 1 is installed on the opening 3 by sealing member 8, be fixed on the Fuel Tank 2 with installing 1 oil sealing.Therefore, fuel supply system 1 of the present invention is a kind of by simply it being installed to the module of installing on the Fuel Tank 2, and therefore, it can improve the efficient of erection work widely.
The inside of the element body 4 of device 1 is empty, is suitable for holding pump 5 and other element, simultaneously as secondary Fuel Tank 16.In other words, element body 4 plays a part container, therefore the fuel 42 drawn of pump 5 temporarily is stored in the element body 4, thereby has avoided any inappropriate fuel feeding, and these unaccommodated fuel feedings result from the motor bike climbing or sharply in the vibration.Simultaneously, as shown in figure 10, traditional secondary Fuel Tank generally comprises some elements, and the secondary Fuel Tank of apparatus of the present invention 1 includes only an element body 4.Therefore, device 1 component number that has has reduced, so reduced manufacturing expense.
As seeing from Fig. 2 and 3, retainer 9 is installed on the top of container 4b, and plays a part to close secondary Fuel Tank 16.Pump 5 and filter 6 are installed by retainer 9, and are installed in the element body 4.Simultaneously, fuel suction port 10 is arranged in the below of pump 5, thereby from the bottom sucking-off fuel 42 of secondary Fuel Tank 16.Sucking hole 10 is provided with filter 13, thereby makes fuel 42 remove the foul of thick piece.
People know that lid 11 provides the space for check valve 20 is installed, and it is as connector simultaneously.Therefore, reduced and installed 1 size and weight thereby lid 11 has not only reduced unnecessary space, thereby and eliminated the needed in other cases space of check valve and reduced height of devices.
In addition, the connecting bridge that the lid 11 of pump 5 and device is coupled together is designed to save the space.More particularly, its top of pump 5 is provided with it is connected to the recess 22 that covers on 11 itself.On the other hand, the connecting bridge that it is connected to the lid 11 on the pump 5 itself is provided with the protrusion (bonding part) 23 that engages with recess 22.Therefore, when recess 22 and protrusion 23 are meshing with each other when installing, pump 5 and lid 11 have just linked together.With regard to this layout, can save the space to pump 5 and lid 11 connecting bridges that couple together widely, thereby reduce height of devices.People know that on the other hand, pump 5 can be provided with protrusion, are provided with the recess that connects them and cover 11.
Simultaneously, filter 6 is provided with joint 12 in the bottom, and this joint 12 is connected in the pressure regulator 7.Fig. 6 is the schematic cross-section partial view of the profile of pressure regulator mounting portion.As shown in Figure 6, joint 12 is arranged between the bottom and discharge orifice 14 of filter 6, and this discharge orifice 14 is outstanding from the bottom of element body 4.Pressure regulator 7 is connected on the core of joint 12.Therefore, the fuel that pump 5 is supplied with has carried out the pressure adjustment by pressure regulator 7, arrives driving engine then forward, and therefore unnecessary fuel turns back in the Fuel Tank 2 by pressure regulator 7.
On the other hand, to be used in be that pressure regulator 7 is arranged on the side of fuel supply system in the fuel feed system of a kind of so-called less return system (return-lesssystem) to device 1.Pressure regulator 7 is arranged in the secondary Fuel Tank 16, and all fuel that return from pressure regulator 7 turn back in the secondary Fuel Tank 16.Therefore, fuel supply system 1 of the present invention does not turn back to the fuel 42 in the secondary Fuel Tank 16 shortcoming of above-mentioned well known device of the outside of secondary Fuel Tank 16, so it can supply to fuel in the driving engine with high stability benchmark.
The discharge orifice 14 that is connected on the bottom of joint 12 communicates with fuel feeding mouth 15 on the bottom that is arranged in element body 4.Therefore, the fuel that pump 5 is drawn by cover 11, filter 6, joint 12 and discharge orifice 15 supply in the fuel feeding mouth 15, then by fuel pipe 43 further supply engines.The fuel flow rate that supplies in the pipe 43 is carried out pressure control by pressure regulator 7, and any excessive fuel turns back in the secondary Fuel Tank 16.
As from seeing Fig. 7, its side of container 4b is provided with fuel inlet port 17, and this inlet port 17 is used for fuel is joined in the secondary Fuel Tank 16.Fig. 7 is the schematic side elevation of device 1, and Fig. 8 is a diagrammatic plan view, and wherein retainer 9 and lid 11 have removed from installing 1.When carrying out fuel feeding, usually need motor bike to be erected on trailing wheel and/or the tilting path, and support by its support.In addition, the center of gravity of motor bike moves to rear wheel-side, and it supports (prance) on trailing wheel when quickening.Also have, during climbing, the front wheel side of motor bike is than rear side height.Under any of these condition, need consume more fuel with former ratio engine mutually.By these situations are taken into account, the inlet port 17 of device 1 is arranged on such position: on this position, when the main body of motor bike is tilting, fuel is flowed out, perhaps when the motor bike main body was tilting, inlet port 17 up.With regard to this layout, though motor bike be erected on the trailing wheel or it when upright (prance), can prevent that also fuel from flowing out secondary Fuel Tank 16.
When motor bike is erected on the trailing wheel, the front portion of motor bike main body up, and when motor bike keeps static and supports by support, this side relative with that side of the support of motor bike is up.Therefore, the opening 17a of this device inlet port 17 of 1 is arranged near on the position of body front end and relative with this side, and support is provided on this side, therefore when the front portion of motor bike up the time it up, so can prevent the fuel outflow under the situation about on any, finding.Therefore, even be erected on the trailing wheel or on the tilting support, can prevent that also fuel from passing through inlet port 17 and flowing out secondary Fuel Tank 16, therefore at it at motor bike, can not destroy the purpose that secondary Fuel Tank 16 is installed, and can stablize for a long time and reliably to the driving engine fueling.
Simultaneously, the position of fuel inlet port 17 is selected by adopting both of these case: motor bike is erected on the trailing wheel and motor bike leans against on its support, and on the other hand, it can be selected by any situation of main consideration.If the situation that motor bike is erected on the trailing wheel is considered to principal element, inlet port 17 is arranged on the position near the front portion of motor bike so.On the other hand, if motor bike situation tilting and that lean against on its support is considered to principal element, inlet port 17 will be arranged on the position relative with the sidepiece of support so.
The inside of fuel inlet port 17 has labyrinth structure.More particularly, shown in Fig. 7 and 8, inlet port 17 is provided with partition wall 18, and this partition wall 18 extends to the inside of element body 4 from opening 17a along periphery, thereby forms labyrinth 19.The inner wall limit of wall 18 and flange 4 goes out labyrinth 19.Owing to constructed labyrinth 19, therefore the fuel that flows in the secondary Fuel Tank 16 can not flow out Fuel Tank easily.Therefore, the structure in the position of selected inlet port 17 and labyrinth 19 makes fuel flow out the dangerous minimum of secondary Fuel Tank 16.
Simultaneously, the resistance of thermally dependent resistor 24 changes along with the variation of ambient temperature function, and thermally dependent resistor 24 is arranged on the inside of element body 4, thereby and as in the warning sensor driver Fuel Tank left fuel quantity.Usually, the internal temperature of Fuel Tank raises along with the minimizing of the fuel quantity that is stored in its inside.Therefore, by means of the variation of surveying ambient temperature, thermally dependent resistor 24 detects the fuel quantity that remains in Fuel Tank, and the fuel 42 in Fuel Tank is under certain extreme value scope, and by means of the fact that driver fuel has been used up, it has produced warning.
Fig. 9 is the schematic side elevation how diagram thermally dependent resistor 24 is installed and connected up.As shown in fig. 9, negative (ground wire) lead 25a of thermally dependent resistor 24 carries out branch from the negative conductor 25b of pump 5.In addition, as Fig. 2 and 9 were seen, by means of thermally dependent resistor arm (sensor retainer) 26, thermally dependent resistor 24 was fixed on the element body 4, and the thermally dependent resistor arm is made by conductive material such as metal filament.Ground wire connecting bridge 26a is being formed on the arm 26 on the position near thermally dependent resistor 24, and keeps being electrically connected with lead 25a.Therefore, by part 26a and lead 25a, arm 26 is connected on the lead 25b.
On the other hand, filter connecting bridge 26b is formed on the arm 26 on that side relative with part 26a, so arm 26 is kept in touch by the periphery of part 26b and filter 6.Therefore, filter 6 is connected on the lead 25b by arm 26, therefore passes through arm 26 and ground connection.
Simultaneously, the periphery wall of filter 6 is formed by metal or electroconductive resin material, thereby makes and anyly discharged by the static that filter element produced by fuel, and filter element is arranged on the inside and made by paper or resin.Therefore, the static that produces in filter 6 flows among the lead 25b by arm 26 and lead 25a.With regard to installing 1 this layout, arm 26 is as the ground wire of filter 6, so thermally dependent resistor 24 and filter 6 are shared common ground wires.In other words, the ground wire of the filter 6 that needs has in other cases saved, and therefore only needs a lead job, thereby thermally dependent resistor 24 and filter 6 ground connection, has therefore reduced the number of number of parts and manufacturing step.
People know that above-mentioned layout not only can be used for thermally dependent resistor, but also can be used for sensor, on the other hand, with essential lead this sensor are installed in the Fuel Tank.If this is the case, the retainer of sensor is formed by conductive material so, and when it and filter 6 are kept in touch ground connection, thereby come to discharge by retainer to static.
Hereinbefore, with reference to embodiment, the present invention that the inventor invented is described in detail.But the present invention is not limited to the above embodiments, and can carry out various modification in the scope that does not break away from main points.
When pump 5 and filter 6 were installed on the retainer 9 in the foregoing description, it can be arranged to so on the other hand: pressure regulator 7 was arranged on the upstream with respect to filter 6, and joint 12 is installed on the retainer 9.Then, retainer is installed pump 5 and pressure regulator 7 (joint 12) can be kept by retainer 9 and lid 11.If this is the case, as the situation of the pressure regulator 7 among the embodiment in the above, filter 6 needn't be arranged in the Fuel Tank 2.
In addition, when check valve 20 was contained in the lid 11 of said apparatus 1, it can be arranged on downstream part with respect to filter 6 on the other hand.Then, filter 6 is provided with the gas release hole.
Also have, when device 1 was installed on the bottom side of above-mentioned Fuel Tank 2, it can be installed on the top side of Fuel Tank 2 as well known device shown in Figure 10.In addition, form one also as in the element body 4 of said apparatus 1 at flange 4a and container 4b, they needn't be integral shaping, and in other words, they can be separated from each other formation.Be installed on the top side of Fuel Tank 2 if install 1, can save flange 4a so.Then, element body 4 can adopt the form of end cover, and perhaps on the other hand, it can adopt the form at the cover of top and place, bottom opening, and is installed on the bottom of Fuel Tank 2.
In addition, at fuel supply system described the while of the present invention in the above according to motor bike, but application of the present invention is in no way limited to motor bike, and it can be used as such fuel supply system equally: this feedway can be applied to has combustion engine as on the automobile in prime power source, the trailer that is used for loading the chest shell on the golf course, lawn mower, industrial machine, portable engine and other machine.Also have, the fuel that uses with fuel supply system of the present invention is not limited to gasoline, also can be light oil or kerosene on the other hand.
As mentioned above, because fuel supply system of the present invention has container, and this container is provided with the fuel inlet port, and this inlet port is to be provided with like this: when the main body of motor bike that is loaded with this device or automobile tilts, this inlet port up, therefore if the tilting long time of main body, fuel can not flow out secondary Fuel Tank by the fuel inlet port yet, so driving engine stable supplying fuel for a long time.
If when motor bike lean against side stand or support (prance) on trailing wheel the time fuel inlet port be arranged to up motor bike supply engine fuel long-term and stably so.
If the inside of fuel inlet port has labyrinth structure, prevent that so fuel will be further improved by the effect that the fuel inlet port flows out.
At last, with regard to fuel supply system of the present invention, the thermally dependent resistor that remains the sensor of the fuel quantity in Fuel Tank as sensing is installed by the thermally dependent resistor arm, and this thermally dependent resistor arm is formed by conductive material, and the thermally dependent resistor arm is electrically connected on the filter in the end, and other end ground connection, so it can be as the grounding terminals of filter.Then, thermally dependent resistor and this structure have been shared common grounding terminals, thereby have saved the earth lead of filter.Correspondingly, thermally dependent resistor and filter can come ground connection by a common lead, thereby have reduced the quantity of number of parts and manufacturing step.
