Embodiment
Refer to Fig. 3 and Fig. 4, the auxiliary oil pump bracket assembly of the application comprise pressuring adjusting valve base 21 for installing pressure regulator valve, for install fuel level sensor sensor stand 22, for installing the guide rod seat 23 of guide rod, jet pump and runner 24 thereof.For clear display, jet pump and runner 24 thereof have carried out biopsy cavity marker devices.
Refer to Fig. 5, described pressuring adjusting valve base 21 inside has a cavity, and what be connected with this cavity is one and enters oil pipe 211 and an oil outlet tube 212.Pressure regulator valve 31 can be installed in the cavity of pressuring adjusting valve base 21.The pressure chamber 311 of pressure regulator valve 31 distributes in the form of a ring, is connected with the oil pipe 211 that enters of pressuring adjusting valve base 21.The oil outlet 312 of pressure regulator valve 31 is connected with the oil outlet tube 212 of pressuring adjusting valve base 21.Because the tangent direction of fuel oil along circular pressure chamber 311 enters, and be conducive to the suppression of fluid noise.
Refer to Fig. 6, described sensor stand 22 is formed with a groove 221, and fuel level sensor 32 is just arranged in this groove 221.After fuel oil in the saddle fuel tank chamber at auxiliary oil pump bracket assembly place is drained, can have some fuel oils in this groove 221, fuel level sensor 32 immerses wherein, is conducive to the slip lubrication of fuel level sensor 32 contact.Described fuel level sensor is used for exporting the amount of fuel in oil-storing barrel.
Refer to Fig. 7 a, this is a kind of form of guide rod seat 23.It comprises the guide portion 231 of a tubulose, and wherein have a through hole, guide rod 33 is just arranged in this through hole.The sidewall of this through hole has many radially-inwardly protruding convex tendons 232.Preferably, the cross section of these convex tendons 232 presents semicircle, thus reduces the area of contact with guide rod 33, reduces catching phenomenon during assembling.In one end of this guide portion 231, there is one or more back-off 233, the approximate formation conical surface of these back-offs 233.The stub end of guide rod 33 by back-off 233 limit and prevent from.The guide rod seat 23 of this form is suitable for the guide rod 33 being fixedly wound with spring.
Refer to Fig. 7 b, this is the another kind of form of guide rod seat 23.The basis of the guide rod seat shown in Fig. 7 a also add baffle plate 234, and it is arranged on the dead ahead of the through hole of guide portion 231.Guide rod 33 is just arranged in the through hole of guide portion 231, and one end of guide rod 33 limited by baffle plate 234.The guide rod seat 23 of this form is suitable for the guide rod 33 of any pattern.
Refer to Fig. 8 a and Fig. 8 b, described jet pump and runner 24 thereof have two entrances (being called filler opening 241, inlet port 242) and an outlet (being called oil outlet 243).Its inside also has nozzle 244.Filler opening 241 connects the oil outlet tube 212 of pressuring adjusting valve base 21, namely connects the oil outlet 312 of pressure regulator valve 31.The low-voltage fuel that pressure regulator valve 31 flows out enters jet pump from filler opening 241, is ejected into oil outlet 243 place pipeline again from nozzle 244.Fuel oil in fuel tank is drawn into jet pump from inlet port 242 by negative pressure produced in the process, also enters into oil outlet 243 place pipeline.If the pipeline between filler opening 241 to nozzle 244 is called the first pipeline 245, pipeline between inlet port 242 to oil outlet 243 is called second pipe 246, so the first pipeline 245 is nested in the middle of second pipe 246, and being provided with runner (namely there is the gap that can flow through for liquid) between the two, the fuel oil that inlet port 242 sucks flows to oil outlet 243 from this runner just.This jet pump and runner 24 thereof can be made up of a secondary mould together with the remaining part of auxiliary oil pump bracket assembly, decrease mould development and drop into.Oil outlet 243 and nozzle 244 are upwards loosed core, and inlet port 242 is loosed core downwards, and filler opening 241 is side core-pulling together with pressuring adjusting valve base 21.Each pulled core structure has constructed jet pump and runner 24 thereof, and core rod is without comparatively fine texture, ensure that mould strength.
Alternatively, at inlet port 242, place can arrange filter screen, filter etc., is fallen by the contaminant filter in fuel oil.
Fig. 9 a ~ Fig. 9 c gives three kinds of different embodiments of jet pump and runner 24 thereof.Wherein filler opening 242 place pipeline, oil outlet 243 place pipeline all can be obliquely installed, and nozzle 244 aims at the direction of oil outlet 243 all the time.
Figure 10 a ~ Figure 10 c gives three embodiments of the sectional shape of the first pipeline 245.Wherein the sectional shape of the first pipeline 245 can be rectangle, rhombus, circle, ellipse etc., and the caliber of second pipe 246 can be even, also can be uneven.
Figure 11 gives the another kind of embodiment of jet pump and runner 24 thereof.Wherein filler opening 241, oil outlet 243, nozzle 244, first pipeline 245 all only have one, but inlet port 242 has two.Be independently two from the part second pipe 246 of inlet port 242 to the first pipeline 245, connect two inlet ports 242 respectively.One is combined into from the first pipeline 245 to the part second pipe 246 of oil outlet 243.
Figure 12 a, Figure 12 b give other two kinds of embodiments of jet pump and runner 24 thereof.Wherein filler opening 241 only has one, and inlet port 242, oil outlet 243, nozzle 244, first pipeline 245, second pipe 246 all have two.This is equivalent to low-voltage fuel that pressure regulator valve 21 flows out and enters two functionally separate but jet pump closely and runners 24 thereof in structure simultaneously.Apparently, the direction of each pipeline can be arranged arbitrarily.
From the various embodiments of the jet pump shown in Fig. 8 a ~ Figure 12 b and runner 24 thereof, can be made up of a secondary mould together with the remaining part of auxiliary oil pump bracket assembly.
The application's auxiliary oil pump bracket assembly shown in Fig. 3 and Fig. 4, its entirety by a secondary Making mold, thus can decrease number of spare parts, reduces assembling complexity, and makes compact to design, compact, among the fuel tank that can be installed to inner space anxiety.
These are only the preferred embodiment of the application, and be not used in restriction the application.For a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the application.
