Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of double fuel fuel pump of the present invention, comprises main oil pump 1, auxiliary oil pump 2, and described main oil pump 1 is in parallel with auxiliary oil pump 2; Share a pair of bowl cover 3 between described main oil pump 1 and the described auxiliary oil pump 2; On two branch roads of oil circuit in parallel, main oil pump 1 is used for the conveying of kerosene, and auxiliary oil pump 2 is used for the conveying of gasoline.
Be provided with the filler opening 11, oil suction chamber 12, the middle oil pocket 13 that mutually are communicated with successively in the main oil pump 1, go out oil pocket 14, oil outlet 15, described middle oil pocket 13 respectively with oil suction chamber 12, go out oil pocket 14 joints and be provided with equal check valve sheet 16; Be provided with suction port 31, the air cavity 32 that is interconnected in the described double-fuel oil pump lid 3, be provided with barrier film 33 between described air cavity 32 and the described middle oil pocket 12 corresponding settings, barrier film 33 employings be the polyester dacron film; Also be provided with spring 17 in the described main oil pump 1; Described spring 17 1 ends connect on the main oil pump body, and the other end is connected on the barrier film 33
During work, the cylinder block of the C termination motor of double-fuel oil pump lid 3, because the motion of piston has changed the volume in the double-fuel oil pump lid 3, so that so double-fuel oil pump covers the 3 interior air pressure (being depicted as the flow direction of air in air cavity 32 such as accompanying drawing 1 middle and upper part four-headed arrow) of rule variation that produced regular the passing in and out from C of air meeting, because what barrier film 33 adopted is the polyester dacron film, so can drive barrier film 33 vertical tremors from the air of C end turnover, spring 17 plays certain power-assisted effect for the resilience of barrier film 33, barrier film 33 vertical tremors so that the volumes in the air cavity 32 change, in like manner, air cavity 32 and middle oil pocket 13 be alternating floor barrier film 33 only, the vertical tremor of barrier film 33 so that the volume of middle oil pocket 13 also along with variation, because flowing to, presses shown in the accompanying drawing 1 from A to B the effect fuel oil of check valve sheet 16, check valve sheet 16 adopts the elastic stainless steel band to make, when fuel oil flows into from the A end, check valve sheet 16 can be opened, can prevent effectively that fuel oil from flowing backwards, pressing in the accompanying drawing 1 direction shown in the arrow flows, and can only flowing by the direction of arrow shown in the accompanying drawing 1, thereby the pumping of realization kerosene.
2 are provided with secondary oil inlet hole 21, the first intercommunicating pore 22, secondary oil pocket 23, the second intercommunicating pore 24, the secondary oil outlet 25 that mutually is communicated with successively in the auxiliary oil pump; Be provided with suction port 31, air cavity 32, intercommunicating pore 34, the second air cavity 35 that mutually is communicated with successively in the described double-fuel oil pump lid 3; Be provided with rubber film 36 between secondary oil pocket 23 and the 35 corresponding settings of the second air cavity; Be provided with the first valve 37, the second valve 38 in the rubber film 36; Described the first valve 37 and the second valve 38 cover respectively on secondary oil inlet hole 21, secondary oil outlet 25 end faces fully.
Be air-flow direction such as four-headed arrow in the accompanying drawing 1, because the C end is connected on the cylinder block of motor, therefore the variation of motor internal air pressure can impel volume in the air cavity 32 along with variation, air cavity 32 internal air pressures arrive in the second air cavity 35 by intercommunicating pore 34, impel the air pressure rule in the second air cavity 35 to change, therefore drive thereupon up and down springing of rubber film 36, volume rule in the secondary oil pocket 23 is changed, so that the fuel oils in the auxiliary oil pump 2 as shown in Figure 2 the unidirectional arrow direction flow, thereby realize the pumping of gasoline.
Shown in accompanying drawing 1,2, gasoline enters from the E end and enters F end (arrow is that fuel oil flows to signal) after secondary oil inlet hole 21 arrives secondary oil outlet 25 by the first intercommunicating pore 22, secondary oil pocket 23, the second intercommunicating pore 24, wherein secondary oil inlet hole 21 and secondary oil outlet 25 endoporus are respectively by the first valve 37, the second valve 38 cover fully as shown in Figure 3, at this, the first valve 37, the second valve 38 play one-way valve, have realized fuel oil one-way flow and non-adverse current.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
