On the other hand, as Fig. 4 and shown in Figure 6, the petrolift 46 that the fuel supply of fuel tank 12 is arrived motor 13 1 sides is installed on the top of fuel tank 12, opposite with Direct box 16 1 sides side face, while is at the downside of this petrolift 46, the fuel tap 47 that fuel shutoff is supplied with is installed and is configured on the substrate 48, and aforesaid substrate 48 is installed on the end cover 19.This fuel tap 47 is connected with aforesaid operations knob 16f via link 49, rotates open and close fuel tap 47 by making this operation knob 16f.

Below its effect is described.

By drawing wire rope 27 to make 34 rotations of Kick-start portion, drive motor 13, bent axle 13c rotation, the rotor 14b rotation of generating body 14 is generated electricity.

Meanwhile, engine cooling is rotated with fan 35, and therefore, shown in dashdotted arrow among Fig. 5, Fig. 6 and Fig. 7, cooling air flows through from the 1st cooling duct.That is, at first, ambient air flow in the sound-insulating cover 11 from the 1st intakeport 21b, owing near the inboard of the 1st intakeport 21b, dispose controller 15, so, can directly cool off by the ambient air that flows into from the 1st intakeport 21b.Therefore, improved the cooling performance of controller 15.And it is flat rectangular-shaped that this controller 15 is, and therefore the big big face of area can further improve cooling performance towards facial 21j one side of operation (the 1st intakeport 21b one side) configuration.

This cooling air is cooling controller 15 on one side, from the upside of this controller 15 or the downside of this controller 15 and fuel tank 12 pass on one side, be drawn into engine cooling with fan 35 1 sides from the opening 34a of Kick-start portion 34.

Cooling air passes the 1st cooling duct that is formed by air-strainer cover 38, preceding air shield 39 and back air shield 40 in engine cooling with downstream one side of fan 35, cooled engine cylinder 13b and baffler 30, the roughly first half from the relief opening 23b of side cover 23 is discharged to the generator outside then.

On the other hand, bent axle 13c rotation drives generating body cooling fan 36, and therefore, shown in the arrow of dotted line among Fig. 5, Fig. 6 and Fig. 7, cooling air flows through from the 2nd cooling duct.That is, at first, ambient air is inhaled in the sound-insulating cover 11 from the 2nd intakeport 21m, 25a, simultaneously, is stuck in air in the sound-insulating cover 11 to generating body cooling fan 36 1 side flow.

Therefore, cooling air passes through from the side of engine crankcase 13a, is inhaled into by generating side front shroud 43 and cover 44 spaces that form, generating body rear flank, cooling generating body 14.Then, cooling air is discharged from the spout 44b of generating body rear flank cover 44, from the space that is formed by the protruding 44c of shielding, is discharged to the generator outside via the lower portion of the relief opening 23b of side cover 23.

For such cooling air passway, from the 1st intakeport, order by fuel tank 12 and controller 15, motor 13, generating body 14, relief opening 23b is provided with, because fuel tank 12 and the controller 15 that temperature is low is configured in upstream one side, so, can form such air-flow path, promptly, can make air-flow from temperature low fuel tank 12 and high motor one side flow of controller 15 1 side direction temperature, between fuel tank 12 and controller 15 1 sides and motor 13 and generating body 14 1 sides, next door etc. needn't be set, can simplify the internal structure of sound-insulating cover 11.

In addition, this air-flow forms the 1st, the 2nd this two passes of cooling duct, the 1st cooling duct constitutes the air-flow of the 1st intakeport 21b, controller 15, engine cooling fan 35, cylinder 13b, baffler 30, relief opening 23b, and the 2nd cooling duct constitutes the air-flow of the 2nd intakeport 21m, 25a, engine crankcase 13a, generating body 14, generating body cooling fan 36, relief opening 23b.

Such formation two passes makes the higher cylinder 13b of temperature form different systems with baffler 30 1 sides with generating body 14 1 sides, therefore can cool off it effectively respectively.

In addition, owing on generating side front shroud 43, be formed with shielding part 43c, so, shown in Figure 55, can prevent that air from scurrying out from clearance C, suck cooling air easily, in addition, this is processed into forniciform shielding part 43c, can improve the intensity of generating side front shroud 43 self.

Have again, since be formed with between the 1st cooling duct and the 2nd cooling duct cooling air that makes the 2nd cooling duct one side towards below wind direction control device 40c, therefore, the cooling air of discharging from the 2nd cooling duct can't influence the cooling air of discharging from the 1st cooling duct, can carry out exhaust reposefully, so, cooling air by the cylinder 13b in the 1st cooling duct etc. is flowed well, can improve cooling performance, simultaneously, can prevent to interfere with each other, can reduce noise from the wind that two cooling ducts are discharged.In addition, because with the spout 44b of this wind direction control device 40c covering generating body cooling fan 36 1 sides, so, can shield the noise source of these fan 36 grades, can reduce noise.

In addition, by near Configuration Control Unit 15 rear side of the 1st intakeport 21b, can suppress to leak sound with this controller 15, arrangement components can reduce noise at an easy rate in addition.That is,,,, can reduce noise so can suppress to leak into the sound of generator outside because the rear side controlled device 15 of its 1st intakeport 21b covers though the noise of motor 13 1 sides spills from the opening 34a of Kick-start portion 34.

Particularly, owing to form the 1st intakeport 21b in the facial side of the operation of front shroud 21, so, can prevent to spill sound from the 1st intakeport 21b, this is reducing towards effective especially aspect operator's the noise.

Have, it is flat rectangular-shaped that this controller 15 is again, and the big big face of area is towards the facial side configuration of operation, so, can further improve sound insulation value.

Have, because the state to separate with generating body 14 1 sides with the motor 13 of high temperature, the fuel tank 12 and the controller 15 of low-temperature condition are kept in configuration hope with adjoining each other, so can reduce the heat affecting to fuel tank 12 and controller 15 as much as possible again.

In addition, owing to directly this fuel tank 12 and controller 15 are positioned on the end cover 19, so, there is no need with sound-insulating cover 11 supporting fuel tanks 12, or the parts of other configuration supporting, can fuel tank 12 be set at an easy rate with less number of components.

That is, unload screw 24, just can it be disassembled with the order of side cover 23, front shroud 21, back cover 22, under the state that disassembles, the state of inner members such as motor 13 and fuel tank 12 can remain unchanged.

Therefore, can improve the assembling performance, and under the state of pulling down these covers 21,22,23, can keep in repair inner member, because after finishing maintenance, it is just passable only need to install these covers 21,22,23 once more, so, can keep in repair at an easy rate.

By the way, Japanese patent gazette spy opens the existing engine generator of being put down in writing flat 11-200861 number, if unload each cover, then can not keep original state of inner member, and be each self-dispersed state, so, maintainability and assembling poor-performing.In addition, Japanese patent gazette spy opens the existing engine generator that the 2001-27125 grade is put down in writing, and must unload the cover of 6 parts, so operating characteristics is poor.

And, owing to front shroud 21 grades of sound-insulating cover 11 can be independent of fuel tank 12 ground separately, so, under the state that unloads front shroud 21 grades, operation such as can keep in repair at an easy rate.
