Above the protecgulum 4a of the face side that constitutes top combination cover 4, be provided with control box 27, this control box 27 comprises a plurality of Switch members 25 such as a plurality of button 25a, various display lamp 25b such as the switch of engine 13 and Out let 25c.Because this control box 27 has certain thickness, so the outstanding as shown in Figure 3 inboard, top that is configured in protecgulum 4a.Therefore, in the inside of protecgulum 4a, controller 18 is disposed in the following side space of projection of this control box 27, the distance between controller 18 and the control box 27 shortens, and can effectively utilize the space.

Control box 27 and controller 18 are configured near the position of fuel tank 17 1 sides, as far as possible with configurations such as heating value generating body 11 how and engines 13 with separating.

On the other hand, as shown in Figure 2, on fuel tank 17 and positions control box 27 and controller 18 opposite sides, be provided with petrolift 19.This petrolift 19 directly is fixed on the side with the highly roughly the same fuel tank 17 of control box 27, is provided with fuel cock 23 as switch valve at downside.

And, between 17a of outflow portion that is arranged at fuel tank 17 bottoms and the petrolift 19 and between petrolift 19 and engine 13 pipe arrangement is being set, constitute the fuel system 22 of 13 fuel supplying from fuel tank 17 to engine.

And, on fuel cock 23, be provided as the bar 24 of operating projection, by making the angle of swing that forms valve body rotation regulation one, not shown with bar 24, can block or be communicated with fuel system 22.This fuel cock 23 is can constitute the mode that locking is carried out in each rotation on the position of the position of valve body full-shut position and full-gear.

On the other hand, on aforementioned control box 27, configuration is used for the operation knob 31 of this fuel cock 23 of switching manipulation.This operation knob 31 can rotate the angle of swing of regulation, can the mode that locking is carried out in each rotation be constituted on the rotational position of distolateral rotational position of the beginning of regulation angle of swing and end side.

And, in this engine generator 1, couple together by connector element 33 between this operation knob 31 and the fuel cock 23.This connector element 33 is made of flexible wire rod as shown in Figure 4, can hold to be configured in the flexible tube 35 with rotating freely.

Side end 33a side at connector element 33, operation knob 31 pivots are propped up in the basic courses department 36 in being fixed in control box 27, utilize bellmouth 34a that the end 35a of flexible tube 35 is fixed in the basic courses department 36, the end 33a of connector element 33 is fixed on the pivot 31a of operation knob 31, utilizes the rotation of operation knob 31 member 33 that can be rotatably connected.

And, because petrolift 19 is with the level configurations identical with control box 27, so fuel cock 23 is configured in than on the low position of operation knob 31, even and there are height difference in operation knob 31 and fuel cock 23, also can be crooked and operation knob 31 reasonably is connected with fuel cock 23 operates by only making flexible connector element 33.

And then, because bar 24 is set on fuel cock 23, by making bar 24 rotation can switch fuel cock 23, thereby, even the user does not hold operation knob 31 and makes its rotation, also can be from removable sidewall lid 5 and swingle 24 under the side dumping opposite with control box 27, block or be communicated with fuel system 22, easy to use.

And, by making the angle of operation knob 31 rotation regulations, make connector element 33 rotations, the angle of fuel cock 23 rotation regulation also can locking, the regulation angle of swing of operation knob 31 is set to such an extent that go out the amount of size of the windup-degree of connector element 33 greatly than the regulation angle of swing of fuel cock 23, thereby, if the angle of operation knob 31 rotation regulations, then on connector element 33, produce and reverse accordingly, can make the angle of swing and the locking of fuel cock 23 rotation regulations with the degree of windup-degree.Therefore, always can make the amount of fuel cock 23 rotation regulation,, also can prevent the angle of swing deficiency of fuel cock 23 even operation knob 31 and fuel cock 23 are separated and bigger by reversing of producing of connector element 33.

In addition, the invention is not restricted to above-mentioned form of implementation, can suitably change, in for example superincumbent explanation connector element 33 exemplarily is expressed as by wire rod and constitutes, but, also can adopt can and from operation knob 31 to fuel cock the correspondingly crooked material of the curved path between 23.And,, also can not be contained in the flexible tube 35 though the connector element that is made of wire rod is contained in the flexible tube 35.

And then, in the superincumbent explanation, be expressed as the example that adopts fuel cock 23 as switch valve, still,, have no particular limits so long as it is just passable to utilize the spinning movement of transmitting from connector element 33 to carry out the valve of switch.

In addition, the past is in the engine generator that utilizes the engine driven power generator body to generate electricity, because the noise that is produced by generating body and engine in generating is big, so utilize sound-insulating cover that they are covered.Particularly carry the engine generator of usefulness, in sound-insulating cover, except generating body and engine, also accommodate all devices such as baffler, fuel tank, controller compactly.And then, as the spy open 2001-27125 number～spy open 2001-27128 communique, spy open flat 11-200861 number, spy open flat 11-200873 number～spy open flat 11-200877 communique etc. put down in writing, engine has been well-known by the engine generator of guard shield and the dual covering of housing.

In such engine generator, be necessary to carry out various maintenances, be necessary machine oil to be injected and discharge for engine.Under the situation of the engine generator that covers engine with sound-insulating cover, be provided with in the part of sound-insulating cover can switch the opening that exposes, the injection of machine oil and discharge are to expose opening via this to inject exhaust port from the machine oil that is fixed on inner engine and carry out.

But because various restrictions, machine oil injects exhaust port and is configured in and exposes on the position that opening separates more or less sometimes.In this case, dispose machine oil mouth ABAP Adapter such as funnel, carry out the injection and the discharge of machine oil in the mode that is connected to machine oil injection exhaust port from the outside of exposing opening.In addition, this machine oil mouth ABAP Adapter is to prepare as the fittings of engine generator.

As Fig. 6 or shown in Figure 9, in engine 113, inject or the machine oil that uses when discharging machine oil injects exhaust port 123 and is that tubular is outstanding to be arranged on the bottom, side of rear side, but utilize the embolism 125 of switch that it is blocked.

On the other hand, as Fig. 5 or shown in Figure 6, on the bonnet 104b of top combination cover 104, be provided with the device of engine 113 and its periphery can be exposed expose opening 105, utilize removable sidewall lid 106 that it is covered.Machine oil injects exhaust port 123 and is exposed opening under this state that exposes opening 105.And, consider and the arrangement of the relation of other device and engine 113 configurations, machine oil is injected exhaust port 123 be configured in and expose on the inner side that opening 105 is separated.

As Fig. 9 or shown in Figure 7, on lower cover 103, inject at machine oil to be provided with on the lower position of vertical direction of exhaust port 123 and have the pass through openings 127 of injecting the broader area of the projection of shape of exhaust port 123 than machine oil.And then, comprise this pass through openings 127 and surround machine oil inject exhaust port 123 under on the position around the position, flange 129 is set upward highlightedly, the side wall portion 103a of lower cover 103 and the entire circumference position at the position under the machine oil injection exhaust port 123 seamlessly are surrounded.

As Fig. 6 or shown in Figure 8, in this engine generator 101, be provided with the machine oil mouth ABAP Adapter 131 that forms by soft resilient material, be installed on the pass through openings 127.

As shown in Figure 8, the machine oil mouth comprises with ABAP Adapter 131: with complete all fluid-tight engagement of pass through openings 127 and block pass through openings 127 choking portion 133, be the ditch shape and be formed at around this choking portion 133 and be installed in mounting groove 135 on the pass through openings 127 removably, one side side in choking portion 133 forms the roughly engine oil flow guiding element 137 in the cross section of コ font, with the mounting hole 139 on that form, that can the be installed to engine 113 continuously mutually machine oil injection exhaust port of engine oil flow guiding element 137 123 peripheries liquid sealing.

This machine oil mouth usually as shown in Figure 9, is installed by mounting groove 135 is coupled on the pass through openings 127 with ABAP Adapter 131, forms to utilize choking portion 133 to block the state of pass through openings 127 fully.

In the engine generator 101 of this structure, when machine oil being injected engine 113 or machine oil discharged, at first, pull down sidewall lid 106, engine 113 and machine oil are injected exhaust port 123 expose from exposing opening 105.Secondly, embolism 125 is pulled down, opened machine oil and inject exhaust port 123.And, as shown in Figure 9, side from the pass through openings 127 of lower cover 103 is pulled down the machine oil mouth with ABAP Adapter 131 below, the mounting hole 139 of this machine oil mouth with ABAP Adapter 131 is coupled on the periphery of machine oil injection exhaust port 123, simultaneously, make the front end 137a of engine oil flow guiding element 137 from exposing opening 105 in the face of the outside.

At this moment, the machine oil mouth injects on the exhaust port 123 with the distolateral machine oil that is fixed on of ABAP Adapter 131, and another distolateral mounting whereby, is engine oil flow guiding element 137 towards engine 113 side descending shape ground and disposes on the part of the lower periphery 105a that exposes opening 105.In addition, because the machine oil mouth is pulled down with ABAP Adapter 131, so opened pass through openings 127.

And, when utilizing the machine oil mouth machine oil to be injected in the engine 113 with ABAP Adapter 131, in this state, need only the front end 137a side that machine oil is fed to the engine oil flow guiding element 137 that exposes opening 105, then machine oil can be injected in the engine 113 by engine oil flow guiding element 137.

And, in this state, when utilizing the machine oil mouth machine oil to be discharged with ABAP Adapter 131, the machine oil mouth is being installed with under the state of ABAP Adapter 131, by engine generator 101 is tilted, the machine oil that can make slave oil inject exhaust port 123 discharges is injected guiding element 137 by machine oil and is directed to front end 137a and is discharged to the outside.

And then, in desire engine generator 1 is returned to common following time of user mode, the machine oil mouth is injected exhaust port 123 with ABAP Adapter 131 from machine oil to be pulled down, and, utilizing embolism 125 that machine oil is injected exhaust port 123 stops up, afterwards, the machine oil mouth is inserted into the pass through openings 127 with ABAP Adapter 131 side below lower cover 103, by installing on the periphery that mounting groove 135 is coupled to pass through openings 127.Then, by sidewall lid 106 is installed, can form common user mode.

Employing has the engine generator 101 of said structure, have and to inject machine oil injection or the discharge machine oil mouth ABAP Adapter 131 that exhaust port 123 carries out dismounting with respect to machine oil, because this machine oil mouth is installed on the pass through openings 127 that is formed on lower cover 103 bottom surface sections removably with ABAP Adapter 131, thereby, when via be formed on the sound-insulating cover 102 expose that opening 105 injects machine oil or when discharging engine 113, as long as pull down the machine oil mouth with ABAP Adapter 131 and attach it to machine oil injection exhaust port 123 from pass through openings 127, then be easy to carry out the injection or the discharging operation of machine oil.Therefore, reduce the restriction that machine oil is injected exhaust port 123 and exposes the position relation of opening 105, improved the degrees of freedom of layout.

At this moment, because the pass through openings 127 of lower cover 103 bottom surface sections is opened, even machine oil is unrestrained in sound-insulating cover 102, the machine oil that falls also can be discharged from pass through openings 127.Therefore, be easy to keep the cleaning of lower cover 103 inside.

And, the machine oil mouth with ABAP Adapter 131 not between the spreadable life, as long as be installed in then can make on the pass through openings 127 its with engine generator 101 formation integratedly with its maintenance, the machine oil mouth is difficult for losing with ABAP Adapter 131.

And, because being configured in machine oil, pass through openings 127 injects on the lower position of exhaust port 123 vertical direction, directly fall the outside so can make slave oil inject exhaust port 123 unrestrained machine oil by pass through openings 127, be difficult for polluting the inside of lower cover 103.

And then, on the bottom surface sections of lower cover 103, owing to form outstanding upward flange 129 in position mode on every side inject exhaust port 123 around the machine oil that comprises pass through openings 127 under, thereby, fall to lower cover 103 even inject exhaust port 123 unrestrained machine oil from machine oil, the machine oil that machine oil is remained in center on by flange 129 inject exhaust port 123 under the position around.Therefore, the machine oil that falls is easy to discharge from pass through openings.And, since the machine oil that falls not extensively scope ground spread in the bottom surface sections of lower cover 103, so can prevent the machine oil that falls whole bottom surface sections is polluted.And then, can machine oil be wiped from pass through openings 127.

And, because the machine oil mouth has the choking portion 133 of stopping up pass through openings 127 with ABAP Adapter 131, even so at sound-insulating cover 102 arranging through openings 127, piston part 133 is stopped up fully as long as pass through openings 127 is blocked, the noise that produces in the work of engine generator 101 just is difficult to be delivered to the outside by pass through openings 127, can improve soundproof effect.

And then, because the machine oil mouth is formed by elastic material with ABAP Adapter 131, so only need make the machine oil mouth resiliently deformable take place with ABAP Adapter 131, then can easily carry out the installation of mounting hole 139 with respect to machine oil supply exhaust port 123, simultaneously, can easily carry out the dismounting of mounting groove 135 with respect to the pass through openings 127 of lower cover 103.

And, the invention is not restricted to above-mentioned form of implementation, but can do suitable variation, for example, though be that example is illustrated to be furnished with the engine 113 that a machine oil that is used to carry out the injection of machine oil and discharges both injects exhaust port 123 above, but the injection that machine oil is set respectively also can be adopted the present invention with the discharge of opening and machine oil with the engine of opening.

And, in the above description, though the engine generators that engine 113 waited all devices all be contained in the sound-insulating cover 102 are illustrated,,, can adopt the present invention equally so long as cover the engine generator of engine with sound-insulating cover.

As mentioned above, adopt the present invention, have and to inject machine oil injection or the discharge machine oil mouth ABAP Adapter that exhaust port carries out dismounting via the opening that exposes that is formed on the sound-insulating cover with respect to machine oil, and this machine oil mouth is installed on the pass through openings that is formed on the lower cover bottom surface sections removably with ABAP Adapter, thereby, when machine oil being injected or discharges engine, only needing that machine oil is pulled down and be installed to the machine oil mouth with ABAP Adapter from pass through openings injects on the exhaust port, can make the injection or the discharging operation of machine oil become easy, simultaneously, because the pass through openings of lower cover bottom surface sections is opened, so even machine oil is unrestrained in sound-insulating cover, the machine oil that falls is discharged from pass through openings, be easy to keep the cleaning of lower cover.And the machine oil mouth is installed on the pass through openings when not using with ABAP Adapter, can form under the state of one its maintenance at itself and engine generator, and the machine oil mouth is difficult for losing with ABAP Adapter.

And, because being configured in machine oil, pass through openings injects on the lower position of vertical direction of exhaust port, can directly fall the outside by pass through openings so inject the unrestrained machine oil of exhaust port from machine oil, be difficult for lower cover inside is polluted.

And then, on the bottom surface sections of lower cover, owing to form outstanding upward flange in position mode on every side inject exhaust port round the machine oil that comprises pass through openings under, thereby, fall to lower cover even inject the unrestrained machine oil of exhaust port from machine oil, this machine oil that falls also can remain in the machine oil that surrounds by flange inject exhaust port under the position around, be easy to discharge described machine oil from pass through openings, and, can prevent the oil pollution that the whole bottom surface sections of lower cover is fallen.

And, because the machine oil mouth has the choking portion of stopping up pass through openings with ABAP Adapter, even so at the sound-insulating cover arranging through openings, if pass through openings is clogged fully with choking portion, then the noise that produces in the work of engine generator is not easy to be delivered to the outside by pass through openings, so can improve soundproof effect.

And then, because machine oil mouth ABAP Adapter is made of elastic material,, simultaneously, can easily carry out dismounting to the pass through openings of lower cover so carry out dismounting if make the machine oil mouth then can easily supply exhaust port to the machine oil of engine with the ABAP Adapter resiliently deformable.

As mentioned above, adopt technological scheme 1 described invention, owing near control box, dispose fuel tank, to clamp the mode of this fuel tank, in a side opposite the aforementioned switches valve is set with aforementioned control box, the operation knob of operating this switch valve is configured on the aforementioned control box, utilize flexible connector element to connect aforementioned operation knob and aforementioned switches valve, by operation aforementioned operation knob, can carry out switch to the aforementioned switches valve via aforementioned connector element, thereby, even operation knob and switch valve are configured on the position that is separated from each other that can not straight line be connected, also can they be coupled together, can utilize operation knob that switch valve is carried out switch by making the connector element bending.

Therefore, can on control box, dispose switch valve is carried out the operation knob of switch and carries out remote operation, thereby can improve operating characteristics, and, even operation knob is configured on the control box, also switch valve can be configured on the arbitrary position of an opposite side with control box in the mode of clamping fuel tank, reduce restriction, can increase the degrees of freedom of each member configuration in the sound-insulating cover the switch valve configuration.

And, adopt technological scheme 2 described inventions, because with the level configurations petrolift identical with control box, deploy switch valve below petrolift, therefore, can increase the curvature R of the connector element of attended operation knob and switch valve, reasonably attended operation knob and switch valve.

And then, adopt technological scheme 3 described inventions, setting operation projection on switch valve, can carry out switch to switch valve by the rotary manipulation projection, thereby, even do not control and the rotary manipulation knob, also can block or the coupling cock valve from a side opposite with control box, easy to use.

And, adopt technological scheme 4 described inventions, by making the angle of swing of operation knob rotation regulation, make the connector element rotation, and the angle of swing of switch valve rotation regulation and can locking, because the regulation angle of swing of operation knob is set to such an extent that go out to be equivalent to the amount of the windup-degree of connector element greatly than the regulation angle of swing of switch valve, thereby, as long as angle with operation knob rotation regulation, then on communication member, produce reverse suitable, can make the angle and the locking of switch valve rotation regulation with windup-degree.Therefore, even operation knob and switch valve are separated and produce big reversing, also can prevent the angle of swing deficiency consistently with the amount of switch valve rotation regulation.That is, reverse, also owing to making the big angle of operation knob speed ratio switch valve, so can carry out switch to switch valve reliably even on connector element, produce.
