Compared with the prior art, the electric fuel pump assembly has the advantages of flange installation and utilization space saving, low noise and low cost.
Description
Technical field
The utility model relates to a kind of electric fuel pump assembly, relates in particular to the electric fuel pump assembly that a kind of flange plate installing space is big, noise is low and with low cost.
Background technique
Electric fuel pump assembly is installed on the automotive oil tank through flange plate, and having for motor provides the fast supply, control electric injection system pressure of fuel oil, accurately feeds back the delta data of oil level in the fuel tank and make fuel tank inner and outer air pressure phase equality function.
At present; Integrated numerous component such as Tipping valve, pressure valve, tubing interface, wire harness interface, pole on the flange plate of widely used electric fuel pump assembly on the market; Make that the available installing space of flange plate is very limited, cause the installation utilization ratio of flange plate low.In addition, the pump core of existing electric fuel pump assembly is installed in the end bucket, because fuel tank can produce certain noise in the process of operation; And end bucket is the container of an opening; Therefore, can in fuel tank, propagate, make that the noise of car load is relatively large by the noise that the pump core produces.And; In order to reduce the influence of giving the pump core owing to the fuel tank shattering zone; Also collet is installed in pump core bottom and antivibration pad carries out damping; It is inner that said collet and antivibration pad all are integrated in end bucket, and the installation of more said inner matter has improved manufacturing and assembly cost to a certain extent, makes that the cost of production of electric fuel pump assembly is higher.
In sum, existing electric fuel pump assembly exists the flange plate installation to utilize the shortcoming that the space is limited, noise is big and cost is high.
The model utility content
The purpose of the utility model is to provide a kind of electric fuel pump assembly, to solve the flange plate that electric fuel pump assembly exists in the existing technology technical problem that utilization ratio is low, noise is big and cost is high is installed.
For achieving the above object, the utility model provides a kind of electric fuel pump assembly, comprising: flange plate, oil pump bracket, pressure valve, pump core and end bucket, and said flange plate is provided with flange pole, oil inlet pipe and oil outlet tube; Said oil pump bracket is connected with bucket of the said end with said flange pole respectively; Said pressure valve is arranged on the said oil pump bracket and with said oil outlet tube and is connected; Said pump core is arranged in the bucket of the said end and is connected with said oil pump bracket with said oil inlet pipe respectively.
According to the described electric fuel pump assembly of the utility model preferred embodiment, its pressure valve is provided with an elastic bumps, correspondingly is provided with one first buckle on the oil pump bracket, and said first buckle is connected with said elastic bumps snapping.
According to the described electric fuel pump assembly of the utility model preferred embodiment; Its pump core bottom is provided with a groove; Correspondingly be provided with one second buckle and one the 3rd buckle on the oil pump bracket, said second buckle is connected with said groove snapping respectively with one the 3rd buckle.
Compared with prior art, the utlity model has following advantage:
1, the pressure valve of said electric fuel pump assembly is installed on the oil pump bracket, has broken the narrow limitation of conventional electric fuel oil pump assembly flange plate utilization fermentation, and the installation of having practiced thrift flange plate utilizes the space, improves the installation utilization ratio of flange plate.
2, the oil pump bracket of said electric fuel pump assembly and end bucket constitute an enclosed environment, and the pump core is installed in the said enclosed environment, and the noise that is produced by the pump core can fall in conductively-closed, effectively reduces noise.
3, said electric fuel pump assembly directly is buckled in the pump core on the oil pump bracket; Oil pump bracket is connected with end bucket, has cancelled the use of collet, antivibration pad, thereby has practiced thrift collet, the new die sinking tool of vibration pad and the relevant cost in the manufacture process; Greatly reduce cost of production, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model electric fuel pump assembly;
Fig. 2 is the utility model embodiment's a end barrel structure ssembly drawing;
Fig. 3 is the utility model embodiment's a end barrel structure explosive view;
