By driving cooling pump 37, the refrigerant fluid 22 in the condensate tank(trap) 20 to cooling off in the adsorption tower 33,34, improves the adsorption efficiency of adsorbent 35 in cooling pipe 36 circulations.
Bottom at adsorption tower 33 connects the aspirate tube that has clamped open and close valve 38, connects the aspirate tube that has clamped open and close valve 39 in the bottom of adsorption tower 34.Here, the aspirate tube that has clamped the aspirate tube of open and close valve 38 and clamped open and close valve 39 is the aspirate tube of aspirate tube 40 branches that are communicated with atmosphere, clamps throttling element 41 on aspirate tube 40.
On the other hand, connect the freeing pipe that has clamped open and close valve 42, connect the freeing pipe that has clamped open and close valve 43 on the top of adsorption tower 34 on the top of adsorption tower 33.Like this, clamp the freeing pipe and the freeing pipe interflow that has clamped open and close valve 43 of open and close valve 42, constituted freeing pipe 44.Clamp safety valve 45 on freeing pipe 44, the end of freeing pipe 44 is communicated with atmospheric side.
Have again, connect the circulating pipe that has clamped open and close valve 46, connect the circulating pipe that has clamped open and close valve 47 on the top of adsorption tower 34 on the top of adsorption tower 33.Clamp the circulating pipe and the circulating pipe interflow that has clamped open and close valve 47 of open and close valve 46, constituted circulating pipe 48.
On circulating pipe 48, clamp vacuum pump 49, and circulating pipe 48 is connected the attraction side of vacuum pump 49 (second pump).
Like this, the circulating pipe 48A that is connected the discharge side of vacuum pump 49 is connected the junction of two streams B1 in the zone of attraction side of compressing pump 19 in Through Flow Line (TFL) 15, with Through Flow Line (TFL) 15 interflow.
In Fig. 2, the pressure sensor of the pressure in the air feed pipe 30 is measured in symbol 50 expressions.
In addition, the pressure sensor of the pressure in the 51 expression metering circulating pipes 48 of the symbol among Fig. 2.
In Fig. 2,, constitute the steam recurrent canal by Through Flow Line (TFL) 15, air feed pipe 30, circulating pipe 48, circulating pipe 48A.
The machine of the control of the vapor recovery system 13 of relevant fuel charger 3 shows with frame table in Fig. 3.
In Fig. 3, the refueling control portion 11 of fuel charger 3 have the on-off signal of fanging noz(zle) switch 10 and flow counter 6 flow signal function and to the function of pump 5 output drive signals and to the function of telltale 12 output volume read-out shows signal.
In Fig. 3, the recovery control part 14 of vapor recovery system 13 has the function of the pressure signal of the temperature signal that receives temperature sensor 28,29 and pressure sensor 50,51, simultaneously, has the function of the timing signal that receives self-timer TM.
In addition, the recovery control part 14 of vapor recovery system 13 has the function to open and close valve 31,32,38,39,42,43,46,47 output open and close controlling signals (switching signal).
Have again, reclaim control part 14 and have to the function of pump 19,37,49 output drive signals with to the function of cooler 23 output drive signals and function from warning signals to alarm 52 that export.
Like this, refueling control portion 11 with reclaim control part 14 and be connected by information, carry out the transmitting-receiving of control signal mutually.That is, from the refueling control portion 11 of fuel charger 3 to the flow signal of the recovery control part 14 input flow rate meters 6 of vapor recovery system 13, be the signal of relevant volume read-out.
Then, with reference to Fig. 2, Fig. 3, the effect of the vapor recovery system 13 of fuel charger is described.
In the business of petrol service station, cooler 23 drives, and the refrigerant fluid 22 in the condensate tank(trap) 20 is cooled to uniform temperature (for example below 5 ℃).Adsorbent 35 in the refrigerant fluid 22 cooling adsorption towers 33,34 that are cooled.
Here, first adsorption tower, 33 adsorbed gasoline steams (absorption process), second adsorption tower 34 carry out the desorb (or regeneration) (absorption process) of the sorbing material of being filled.Under these circumstances, open and close valve 31,39,42,47 is open, and open and close valve 32,38,43,46 is closed.
Here, when a side adsorption tower carries out the absorption of gasoline vapors, be filled in the desorb (or regeneration) of its in-to-in adsorbent at the opposing party's adsorption tower.
If refuel to automobile, and filler nozzle 8 leaves nozzle suspension member 9, then nozzle switch 10 sends out signal for opening.The refueling control portion 11 of receiving out signal drives fuel charger 5, with respect to the recovery control part 14 of vapor recovery system 13, sends content and is the signal in refueling.Receive that from refueling control portion 11 content is the recovery control part 14 drive compression pumps 19 of the signal the oiling.
If filler nozzle 8 is inserted the Fuel Tank of the not shown automobile that goes out, begin to refuel, then the gasoline in the petrol storage tank 1 is by fuel charger 5 force feeds, discharges in the Fuel Tank of the not shown automobile that goes out from filler nozzle 8.At this moment, be presented on the telltale 12, simultaneously, be sent to the recovery control part 14 of vapor recovery system 13 based on the metering result's of flow counter 6 volume read-out signal by the volume read-out of flow counter 6 metering.
When refueling, the Fuel Tank of the automobile that gasoline vapors never illustrates flows out, and the gasoline vapors of outflow is by the effect of compressing pump 19, in the opening 17 inflow Through Flow Line (TFL)s 15 of Through Flow Line (TFL) 15.
The gasoline vapors that flows in the Through Flow Line (TFL) 15 is cooled in condensate tank(trap) 20, and it nearly all liquefies.The gasoline that has liquefied resides in the bottom in the gas-liquid separation chamber 21, returns fuel charger 3, petrol storage tank 1 etc. through Through Flow Line (TFL) 25.
Do not have the gasoline vapors of liquefaction to flow in the condensate tank(trap) 20,, flow in first adsorption tower 33 via open and close valve 31 at air feed pipe 30.In addition, the gas that flows in the adsorption tower 33 passes through compressing pump 19, is pressurized to for example about 250Kpa.
Flow into gasoline vaporss in first adsorption tower 33 and be adsorbed adsorbents 35 absorption in the tower 33, the gas of discharging from first adsorption tower 33 becomes the gas that does not contain gasoline vapors.This gas (gas that does not contain gasoline vapors) is discharged into the atmosphere from freeing pipe 44 via open and close valve 42, safety valve 45.
So, its major part of gasoline vapors that flows out from the Fuel Tank of automobile in oiling is in condensate tank(trap) 20 condensations of vapor recovery system 13 and be liquefied, and is recovered by gas-liquid separation chamber 21.Then, the gasoline vapors that is not liquefied at condensate tank(trap) 20 is adsorbed the adsorbent 35 absorption recovery of tower 33.
The gasoline vapors that is adsorbed at adsorption tower 33 breaks away from from adsorbent 35 when adsorption tower 33 becomes desorption step, via open and close valve 46, through circulating pipe 48, is attracted by vacuum pump 49.The gasoline vapors of discharging from vacuum pump 49 flows into the attraction side of compressing pump 19 through circulating pipe 48A, junction of two streams B1.
That is, gasoline vapors does not escape to outside the fuel charger 3, but is recovered.
Then, with reference to Fig. 4, the switching of the adsorption/desorption of first adsorption tower 33 and second adsorption tower 34 is described.
In the explanation relevant (explanation of the switching of the adsorption/desorption of adsorption tower 33,34) with Fig. 4～Fig. 6, switch to the operation (desorption step) that desorb or regeneration are filled into the in-to-in adsorbent with first adsorption tower 33 from the operation (absorption process) of adsorbed gasoline steam, second adsorption tower 34 is that example describes from the situation that desorption step switches to absorption process.
In Fig. 4, in step STI, judge that whether the recovery control part 14 of vapor recovery system 13 has imported the volume read-out signal from the refueling control portion 11 of fuel charger 3, in other words, whether be in oiling.
If in oiling, promptly, to reclaiming control part 14 input volume read-out signals (step STI is YES), then obtain the aggregate-value (carrying out the summation of volume read-out of switching of the adsorption/desorption of adsorption tower 33,34 since last time) (step ST2) of volume read-out from refueling control portion 11.
Then, judge that the aggregate-value obtained from step ST2 is whether more than threshold value (step ST3).
Here, threshold value is the aggregate-value of volume read-out, as the adsorbent 35 abundant adsorbed gasoline steams that are considered in first adsorption tower 33, sets near the value (for example 500 liters) of saturation conditions.
If aggregate-value reaches threshold value above (step ST3 is YES), then open and close controlling open and close valve (step ST4) makes first adsorption tower 33 of having carried out absorption process carry out desorption step, has carried out second adsorption tower 34 of desorption step and has carried out absorption process.Then, the aggregate-value of replacement volume read-out (aggregate-value of obtaining at step ST2) (step ST5).
In step ST3, if the not enough threshold value (step ST3 is NO) of aggregate-value is then returned step ST1.
In step ST4, carry out desorption step in order to make first adsorption tower 33 that has carried out absorption process, carry out second adsorption tower 34 of desorption step and carried out absorption process, in Fig. 2, close open and close valve 31,39,42,47, open open and close valve 32,38,43,46.
By this open and close controlling of open and close valve, not at the gasoline vapors of condensate tank(trap) 20 liquefaction through having clamped the pipe of air feed pipe 30, open and close valve 32, supply with to second adsorption tower 34.Then, gasoline vapors carries out adsorption treatment by the adsorbent 35 in the adsorption tower 34, and the air that does not contain gasoline vapors is discharged into the atmosphere from freeing pipe 44.
On the other hand, pipe, the circulating pipe 48 of first adsorption tower 33 through having clamped open and close valve 46 is communicated with vacuum pump 49.By driving vacuum pump 49, suction function is in first adsorption tower, 33 inside, and the gasoline vapors that is adsorbed material 35 absorption is attracted by vacuum pump 49, carries out the desorb of adsorbent.
As if the desorb of narrating in more detail with reference to Fig. 2 in first adsorption tower 33, then by driving vacuum pump 49, the gases in the adsorption tower 33 are vacuumized by vacuum pump 49.Here, because open and close valve 38 is open, so the air that has been limited amount by throttling element 41 flows in the adsorption tower 33 that is vacuumized by vacuum pump 49 from aspirate tube 40.Its result is, is negative pressure in the adsorption tower 33, for example-negative pressure about 30Kpa, the gasoline vapors that is adsorbed adsorbents 35 absorption in the tower 33 is also attracted by vacuum pump 49.
The gasoline vapors of discharging from vacuum pump passes through circulating pipe 48A, junction of two streams B1, compressing pump 19, Through Flow Line (TFL) 15, is cooled and condensation at condensate tank(trap) 20.In addition, because check valve 18 is set on Through Flow Line (TFL) 15, so gasoline vapors does not flow out to atmosphere from the opening 17 of filler nozzle 8.
In addition, in order to make first adsorption tower 33 that has carried out desorption step carry out absorption process, carried out second adsorption tower 34 of absorption process and carried out desorption step, in Fig. 2, as long as open open and close valve 31,39,42,47 is closed open and close valve 32,38,43,46 and is got final product.
When the switching of the adsorption/desorption that carries out first adsorption tower 33 shown in Figure 4 and second adsorption tower 34, open and close valve 31,32,38,39,42,43,46,47 among the step ST4 is under the situation more than the threshold value (step ST3 is YES) at the aggregate-value of the volume read-out of being obtained by step ST2, the switching that can instantaneously open and close.
But if the open and-shut mode of instantaneous switching open and close valve, then malleation and negative pressure act on this open and close valve simultaneously, have the situation open effectively or that close that is difficult to.For example, switching to adsorption tower 34 under the situation of absorption process from desorption step, if the switching of instantaneous switching open and close valve 31,32,38,39,42,43,46,47, then for example in open and close valve 47, there is negative pressure from vacuum pump 49 sides (for example-about 30kPa) and acts on the possibility that the adsorption tower 34 interior malleations from compressing pump 19 (for example 250Kpa) act on simultaneously.
Like this, if malleation and negative pressure act on open and close valve 47 simultaneously, the situation that then exists the open and close valve 47 that should close not close fully.
In order to make malleation and negative pressure not act on open and close valve simultaneously, in the illustrated embodiment, when carrying out the switching of absorption process and desorption step, the not instantaneous switching of carrying out open and close valve is switched, but the control shown in the diagram of circuit of execution graph 5.
With reference to Fig. 5, the switching of open and close valve 31,32,38,39,42,43,46,47 is described.
Control shown in the diagram of circuit of Fig. 5 is in the step ST4 of Fig. 4, and first adsorption tower 33 is switched to desorption step from absorption process, and second adsorption tower 34 is switched to from desorption step that stage of absorption process implements.Therefore, in Fig. 5, at first in step ST21, judge whether state for the switching among the step ST4 that should carry out Fig. 4.
If first adsorption tower 33 is switched to desorption step from absorption process, and, second adsorption tower 34 is switched to the stage (step ST21 is YES) of absorption process from desorption step, then that all open and close valves 31,32,38,39,42,43,46,47 is open, simultaneously, the timing (step ST22) of beginning timer TM (with reference to Fig. 3).
Here, the timing carried out of timer TM is in order to carry out the only open certain hour (for example 2 seconds) of all open and close valves 31,32,38,39,42,43,46,47.Therefore, in step ST23, whether judgement is this certain hour (2 second) by the time that timer TM carries out timing.
Carry out the time of timing by timer TM, in other words, all open and close valve open times of 31,32,38,39,42,43,46,47 quilts are if only pass through certain hour (two seconds) (step ST23 is YES), then close open and close valve 31,39,42,47, open open and close valve 32,38,43,46 (step ST24).
In view of the above, first adsorption tower 33 can be carried out desorption step, and second adsorption tower 34 can be carried out absorption process.
If the open and close controlling of step ST24 finishes, then turn back to step ST21.In step ST21, step ST26 carries out the loop of NO, and execution in step ST4 in the control at Fig. 4 promptly, is switched until absorption and desorb.
In control shown in Figure 5, by in step ST22, with the only open certain hour (for example 2 seconds) of all open and close valves 31,32,38,39,42,43,46,47, make the guard system that comprises first adsorption tower 33 even with the pressure of the guard system that comprises second adsorption tower 34.
Under the uniform state of pressure of guard system that comprises first adsorption tower 33 and the guard system that comprises second adsorption tower 34, for example, first adsorption tower 33 can be carried out desorption step, even second adsorption tower 34 opens and closes the open and close valve that desire is carried out absorption process, do not exist malleation and negative pressure to act on the situation of open and close valve 31,32,38,39,42,43,46,47 simultaneously yet, can be smooth and easy and carry out the opening and closing operations of open and close valve effectively, can improve the reliability of open and close valve open and close controlling.
Here, if the open and-shut mode of instantaneous switching open and close valve, then (malleation and negative pressure act on open and close valve simultaneously, and the open and close controlling of open and close valve does not have smooth and easy carrying out in the problems referred to above, become the problem of the state that lacks reliability) the basis on, also have the possibility that produces following such infringement.
As mentioned above, be switched to desorption step at first adsorption tower 33 from absorption process, and, second adsorption tower 34 is switched under the situation of absorption process from desorption step, if in first adsorption tower 33 that has fully adsorbed gasoline vapors, then attract a large amount of gasoline vaporss from the adsorbents 35 in first adsorption tower 33 by vacuum pump 49 from the negative pressure snap of vacuum pump 49.Then, the gasoline vapors that is attracted is discharged from the state that is compressed by vacuum pump 49, collaborates at Through Flow Line (TFL) 15 through circulating pipe 48A, junction of two streams B1.
That is, if the open and-shut mode of instantaneous switching open and close valve then after just switching, is supplied with to the attraction side of compressing pump 19 from the high concentration of vacuum pump 49 discharges and a large amount of gasoline vaporss.
If produced such situation, then be compressed that pump 19 attracts and the amount of the gasoline vapors carried to condensate tank(trap) 20 reduces from the opening 17 of filler nozzle 8.The possibility that perhaps also exists the high concentration of discharging from vacuum pump 49 and a large amount of gasoline vapors to flow backwards to opening 17 sides of filler nozzle 8.
At this infringement, in the illustrated embodiment, come corresponding by the control of carrying out as shown in Figure 6.
Control shown in the diagram of circuit of Fig. 6 is in the step ST4 of Fig. 4, and first adsorption tower 33 is switched to desorption step from absorption process, and second adsorption tower 34 is switched to from desorption step that stage of absorption process implements.
Therefore, even in Fig. 6, also be at first in step ST26, similarly judge whether state with the control of Fig. 5 for the switching among the step ST4 that should carry out Fig. 4.
If first adsorption tower 33 is switched to desorption step from absorption process, and second adsorption tower 34 is switched to stage (step ST26 is YES) of absorption process from desorption step, then stops vacuum pump 49, simultaneously, the timing (step ST27) of beginning timer TM.
In step ST28, judge promptly, whether the time that vacuum pump 49 stops to have passed through certain hour (for example 12 seconds) by the time of timer TM timing.If, then begin the driving of vacuum pump 49 through certain hour (12 second) (step ST28 is YES), simultaneously, replacement timer TM (step ST29).
Then, turn back to step ST26.If turn back to step ST26, then step ST26 carries out the loop of NO, and execution in step ST4 in the control at Fig. 4 promptly, is switched until absorption and desorb.
In control shown in Figure 6, be switched to desorption step from first adsorption tower 33 from absorption process, and, second adsorption tower 34 is switched to the moment of absorption process from desorption step, vacuum pump 49 is only stopped certain hour (for example 12 seconds), and during this period, only the drive compression pump 19.
Here, because during process certain hour (12 second), because the negative pressure of the attraction side of compressing pump 19, or gasoline vapors to a certain degree is from 33 desorbs of first adsorption tower, so, through behind the certain hour,, there is not the situation of discharging high concentrations and a large amount of gasoline vapors from vacuum pump 49 even vacuum pump 49 drives yet.
Like this, by carrying out control shown in Figure 6, be compressed that pump 19 attracts and the amount of the gasoline vapors carried to condensate tank(trap) 20 reduces such infringement, the high concentration of discharging from vacuum pump 49 and a large amount of gasoline vapors have obtained preventing to the such infringement of flowing backwards of opening 17 sides of filler nozzle 8 from the opening 17 of filler nozzle 8.
Then, also with reference to Fig. 7, the control of the fault that detects cooler 23 is described.
In Fig. 7, judge at first whether the power supply of cooler 23 connects (step ST27), if power connection (step ST31 is YES) then reclaims control part 14 temperature degree signal (step ST32) outside temperature sensor 29 obtains.
Then, in step ST33, reclaim the outer temperature degree signal of control part 14 according to input, the refrigerant fluid of setting in the condensate tank(trap) 20 22 is cooled to the following time of uniform temperature.This time for example if outer temperature degree is 30 ℃, then is set 60 minutes, if outer temperature degree is 20 ℃, then is set 30 minutes.Meanwhile, in step ST33, the timing that beginning timer TM carries out.
In step S34, judge the time that refrigerant fluid 22 is cooled, that is, whether only passed through setting-up time by the time of timer TM timing.If the time that refrigerant fluid 22 is cooled has reached setting-up time (step ST34 is YES), then to reclaiming the liquid temperature signal (step ST35) of control part 14 inputs by the refrigerant fluid 22 of temperature sensor 28 meterings.
Then, in step ST36, whether the metering result (the liquid temperature of refrigerant fluid 22) who judges temperature sensor 28 is below uniform temperature (threshold value).If the liquid temperature (step ST36 is YES) below threshold value of refrigerant fluid 22 then is judged as cooler 23 by driven, enter step ST37.
In step ST37, judge whether power supply is OFF, if power supply is not cut off (step ST37 is NO), then return step ST35.On the other hand, if power supply is cut off (step ST37 is YES), then finishing control.
In step ST36, even beginning to have passed through certain hour from power connection, refrigerant fluid 22 does not reach under the following situation of uniform temperature (step ST36 is NO) yet, be judged as produced at cooling system etc. unusual, stop cooler 23, make alarm 52 actions, inform unusual (the step ST38) of cooling system.
Here, even refrigerant fluid 22 is reduced to uniform temperature (threshold value) following (step ST36 is YES), to carry out at step ST37 during the loop of NO, the liquid temperature of refrigerant fluid 22 is warmed up under the above situation of threshold value (step ST36 is NO), stop cooler 23, make alarm 52 actions (step ST38).
According to the control of Fig. 7, because being reported unusually of cooling system, so, by this is carried out correspondence unusually, can prevent that gasoline vapors is not in condensate tank(trap) 22 condensations or liquefaction but flow into the such infringement of adsorption tower 33,34.Its result is, can prevent that the adsorbance in the adsorption tower 33,34 from increasing unusually, and the stage adsorbent before the switching of carrying out adsorption/desorption is saturated, the state of affairs that gasoline vapors is discharged to atmosphere from freeing pipe 44.
Then, with reference to Fig. 8, to when reclaiming gasoline vapors, the control on Abnormal that detects in the system that comprises the adsorption tower (for example first adsorption tower 33) of carrying out absorption process describes.
In Fig. 8, judge whether recovery control part 14 is transfused to content and is the signal in refueling, and in other words, whether is (step ST41) in refueling.If receiving content is the signal (step ST41 is YES) in refueling, then the drive compression pump 19, simultaneously, and the timing (step ST42) that beginning timer TM carries out.
Then, by timer TM, judge whether that after having driven compressing pump 19 pressure that has passed through in Through Flow Line (TFL) 15, gas-liquid separation chamber 21, air feed pipe 30, the adsorption tower 33 that is in absorption process, the freeing pipe 44 is considered to stable certain hour (for example 10 seconds) (step ST43).
If after having driven compressing pump 19, passed through certain hour (for example 10 seconds) (step ST43 is YES), then to reclaiming the pressure signal (step ST44) that the metering result of pressure sensors 50 is represented in control part 14 inputs.
Then, in step ST45, judge by the pressure of pressure sensor 50 meterings whether in certain limit, for example 150Kpa～250Kpa.
If (150Kpa～250Kpa) (step ST45 is YES), the pressure that then is judged as in the system that comprises first adsorption tower 33 is normal with interior in certain limit by the pressure of pressure sensor 50 metering.Then, return step ST41, repeatedly the control of Fig. 8.
On the other hand, in step ST45, exceed at pressure under the situation of certain limit (step ST45 is NO) by pressure sensor 50 metering, if for example low pressure than 150Kpa, be judged as then that the eyelet that is in the fault that produces compressing pump 19, Through Flow Line (TFL) 15 blocks, other unusual, comprise the state that the pressure in the system of first adsorption tower 33 does not boost.On the other hand,, then be judged as because the eyelet obstruction of adsorption tower 33 or freeing pipe 44 etc., comprise that the pressure anomaly in the system of first adsorption tower 33 rises if be the pressure higher than 250Kpa by the pressure of pressure sensor 50 metering.
Even in either case, all stop compressing pump 19, report (step ST46) unusually by alarm 52.
Then, instruction diagram 9, the control on Abnormal that detection is clamped in the system of the adsorption tower (for example adsorption tower 34) of carrying out desorption step describes.
In Fig. 9, reclaim control part 14 and judge whether vacuum pump 49 drives (step ST51), if vacuum pump 49 drives (step ST51 is YES), then begin the timing (step ST52) that timer TM carries out.
Here, timer TM is in order to judge whether that after vacuum pump 49 drives the pressure that has passed through in aspirate tube 40, the adsorption tower 34 of carrying out desorption step, the circulating pipe 48 is considered to stable certain hour (for example 10 seconds) and carries out timing.
In step ST53, whether judgement has passed through above-mentioned certain hour (for example 10 seconds) by the time of timer TM timing, if passed through certain hour (10 second) (step ST53 is YES), then to reclaiming control part 14 inputs and the cooresponding pressure signal of pressure (step ST54) that measures by pressure sensor 51.
In step ST55, judge by the pressure of pressure sensor 51 meterings whether certain limit (for example-10Kpa～-50Kpa) in.If by the pressure of pressure sensor 51 metering is numerical value (step ST55 is YES) in the certain limit, it is normal then to be judged as the system that clamps the adsorption tower 34 of carrying out desorption step.Then, return step ST51, repeatedly the control of Fig. 9.
In step ST55, if by the pressure of pressure sensor 51 metering exceed certain limit (for example-10Kpa～-50Kpa) (step ST55 is NO), if the low pressure of ratio-50Kpa for example, then be judged as because the eyelet obstruction of aspirate tube 40 or adsorption tower 33 etc. comprise that the system of adsorption tower 34 is reduced pressure unusually.
On the other hand,, then be judged as and be in owing to the fault of vacuum pump 49 etc., comprise the state that the system of adsorption tower 34 can not reduce pressure if be the high pressure of ratio-10Kpa by the pressure of pressure sensor 51 metering.
Even in either case, all stop vacuum pump 49, report (step ST56) unusually by alarm 52.
In the illustrated embodiment, can be that the gasoline vapors of a fuel charger 3 is handled by a vapor recovery system 13, also can be the gasoline vapors of many fuel chargers 3 is handled by a vapor recovery system 13.
Under the situation that the steam of many fuel chargers 3 is handled by a vapor recovery system 13, be necessary to carry out the transmitting-receiving of signal, control the driving of compressing pump 19 accordingly with the platform number of fuel charger 3 in refueling by the refueling control portion 11 of each fuel charger 3 and the recovery control part 14 of vapor recovery system 13.Here, can be by easily carrying out drive controlling with the not shown inverter motor drive compression pump 19 that goes out.
Mainly with reference to Figure 10, the control of the driving of the compressing pump 19 of the situation that the steam of many fuel chargers 3 is handled with a vapor recovery system 13 describes.
In Figure 10, in step ST61, the recovery control part 14 of vapor recovery system 13 receives that from the refueling control portion 11 of each fuel charger 3 the expression content is the signal refueling.Then, judge whether reclaim control part 14 only receives that from a fuel charger 3 the expression content is the signal (step ST62) refueling.
In step ST62, only receiving (step ST62 is YES) under the expression content is for the situation of the signal refueling, with common ability drive compression pump 19 (step ST63) from a fuel charger 3.
On the other hand, receiving (step ST62 is NO, and step ST64 is YES) under the expression content is for the situation of the signal refueling, high-speed driving compressing pump 19 (step ST65) from many fuel chargers 3.
Not under the situation that any fuel charger 3 input contents are the signal the oiling (step ST62 is NO, and step ST64 is NO), return step ST61.
Here, under situation, if in step ST63, with common ability drive compression pump 19, then for example with the frequency drives inverter motor of 50Hz with the not shown inverter motor drive compression pump 19 that goes out.
On the other hand, if in step ST65, high-speed driving compressing pump 19 then for example drives inverter motor with 70Hz.
Like this, because the drive frequency variations of inverter motor, in step ST63 and step ST65, the ability difference of compressing pump 19.
Like this, under the situation that the gasoline vapors of situation that the gasoline vapors of a fuel charger 3 is handled by a vapor recovery system 13 and Duo Tai fuel charger 3 is handled by a vapor recovery system 13, by switching the output (perhaps ability) of compressing pump 19, can be recovered in the gasoline vapors of the Fuel Tank outflow of the automobile that never illustrates in the oiling effectively.
As Figure 11, shown in Figure 12, topping up device 3A, 3B can refuel oil and plant different gasoline, that is, also there are two kinds of the steams of the steam of regular-grade gasoline and antiknock fuel in regular-grade gasoline and antiknock fuel, the gasoline vapors that the Fuel Tank of the automobile that never illustrates produces.
In Figure 11, Figure 12, symbol 1R represents the regular-grade gasoline petrol storage tank, and symbol 1H represents the antiknock fuel petrol storage tank.
In the illustrated embodiment, it can be following structure, promptly, as shown in figure 11, making the steam of regular-grade gasoline and the steam of antiknock fuel also is to be reclaimed by mono-vapor recovery system 13, the gasoline vapors that reclaims is at recovery system RR, turns back to regular-grade gasoline petrol storage tank 1R or from the regular-grade gasoline fuel loading system of petrol storage tank 1R.
