As shown in Figure 2, fuel pump components M possesses petrolift 12, retainer portion 13, vapor exhaust tracheae 14 and fuel filter 11.
Petrolift 12 is formed as the substantial cylindrical shape intersected with the upper wall 2 of fuel tank 1, has the motor part 15 being configured in upside and the pumping section 16 being configured in downside.Figure center line CL represents the central axis of petrolift 12.
For motor part 15, use such as not shown brush DC motors.The output shaft of this brush DC motors is supported in the mode that can rotate freely by the not shown bearing etc. of the downside of the upside and pumping section 16 that are configured in motor part 15.
Pumping section 16 is pumps of the non-volume type with not shown impeller (impeller), is housed in not shown pump chamber by the output shaft of the brush DC motors with motor part 15 with the impeller that the mode that can not mutually rotate is combined.Suction port 17 is formed in the underpart of pumping section 16.The negative pressure that pumping section 16 utilizes the impeller rotated by the driving by motor part 15 to produce, by fuel from suction port 17 upwards side pressure give.
Retainer portion 13 possesses the upper shell 18 covering petrolift 12 from top and the lower shell body 19 covering petrolift 12 from below.Upper shell 18 and lower shell body 19 can be divided into two along axis CL direction, and also can assemble integratedly.Upper shell 18 and lower shell body 19 are assembled in the mode of accommodating motor part 15 and pumping section 16 in inside.
The supporting lip (pivot flange) 20 of the upper wall 2 being supported on fuel tank 1 is provided with at upper shell 18.At upper shell 18, supporting lip 20 forms the outside being configured at fuel tank 1 and the fuel discharge outlet 21 be connected with pumping section 16.The not shown fuel supply system that fuel discharge outlet 21 has with motor 4 (with reference to Fig. 5) is connected.
Be formed in the bottom of lower shell body 19 in a thickness direction through bottom this except pore 22.Except pore 22 is in the upstream open of pumping section 16, be there is the mechanism discharged to the outside of pumping section 16 by vapor exhaust tracheae 14 by the steam (bubble) infiltrating (immersion) from inlet hole 23.
One end be configured near except pore 22 of vapor exhaust tracheae 14 is connected with except pore 22.At the other end being positioned at upper shell 18 side of vapor exhaust tracheae 14, lid formula filter (hat type filter: キ ャ ッ プ Off ィ ル タ ー) 24 is installed.Lid formula filter 24 becomes the position (than detecting initial position L2 by the top) of gas phase (air) when being configured at least one in the fuel quantity change procedure being in fuel tank 1.Vapor exhaust tracheae 14 has makes the steam from discharging except pore 22 circulate upward, and by function that lid formula filter 24 is discharged outside pump.
Now, the fuel quantity in fuel tank 1 is for detecting initial position below L2, the other end (upper end portion) of vapor exhaust tracheae 14 is configured in than detecting initial position L2 position by the top.Therefore, vapor exhaust tracheae 14 is discharged from the steam of discharging except pore 22 from the other end in the air layer detected the L2 of initial position.The flow direction of steam is now as shown in arrow F1 in figure.
Fuel filter 11, in hollow shape, is connected with the suction port 17 of petrolift 12.Fuel filter 11 is such as load onto filter cloth 26 in the outside with flexible resinous skeleton 25.As skeleton 25, be preferably formed to such as clathrate.

Fuel filter 11 is as shown in Fig. 3 (a), for the first form A1 as original state, as shown in Fig. 3 (b), when the adsorption of filter cloth 26 has dust D and blocking occurs, along with the rising of the pressure loss of fuel, be the second form A2 shunk than the first form A1 from the first form A1 resiliently deformable of original state.So fuel filter 11 accumulates rebounding force with above-mentioned contraction.
As shown in Figure 4, the second form A2 is at fuel filter 11, and the fuel quantity of fuel tank 1 the other end than vapor exhaust tracheae 14 on the lower detect the situation of initial position below L2 time, petrolift 12 the pressure loss due to fuel filter 11 increase and in the flowing of vapor exhaust tracheae 14 occur reversion time, sucked the gas phase (air) detected on the L2 of initial position by vapor exhaust tracheae 14, the scarce gasoline symptom because aeration causes occurs for the moment.The flowing of gas phase now as indicated by the arrow f 2.
Moreover, pasta (fuel quantity) in fuel tank 1 be in than vapor exhaust tracheae 14 the other end by the top exceed the situation of the 2nd position L3 detecting initial position L2 time, even if the pressure loss of fuel filter 11 increases, owing to can suck by vapor exhaust tracheae 14 fuel detected on the L2 of initial position, above-mentioned scarce gasoline symptom can not be there is.
As shown in Fig. 3 (c), fuel filter 11 has sucked gas phase when being in the second form A2 after, be the first form A1 from the second form A2 elastic recovery.Now, fuel filter 11, owing to occurring to form the clearance D such as crack 1 in the dust D of blocking on filter cloth 26 surface, sucks fuel by clearance D 1 and the pressure loss is reduced.
But because are the states being adsorbed with dust D on the surface of filter cloth 26, therefore fuel filter 11 carries out repeatedly: be punctured into the second form A2 very soon, and is restored to the first form A1 due to aeration.This makes the pulsation producing fuel pressure repeatedly, and when the above-mentioned cycle is repeatedly below regulation, can be judged to be that fuel filter 11 is in the state needing to remove blocking.
Fig. 5 represents the frame assumption diagram of the main portions of fuel supplying device 10.
As shown in Figure 5, fuel supplying device 10 is devices of the running of motor 4 for vehicles such as two-wheeled (motorcycles), possesses control device 31, revolution detector 32, engine load sensor 33, fuel pressure sensor 34, lambda sensor (O
2sensor) 35, alarm buzzer 36.
