Abstract
A fuel pump assembly with a noise reduction cavity relates to an electric fuel pump of automobiles and comprises an oil filter (1), an upper end device of which is provided with a mounting frame (6) and a fuel pump (4), wherein an in-frame device of the mounting device (6) is provided with a fuel pump (4), a fuel pump (4) between the upper part of the fuel pump (4) and the mounting frame (6) is sheathed with an upper shock ring sleeve (5), a fuel pump (4) between the lower part of the fuel pump (4) and the mounting frame (6) is sheathed with a lower shock ring sleeve (2), and a shock ring cavity (3) is formed among the upper shock ring sleeve (5), the lower shock ring sleeve (2) and the mounting frame (6). As the fuel pump is contacted with the upper shock ring sleeve and the lower shock ring sleeve, the noise generated by the vibration of the fuel pump is reduced. Additionally, the upper shock ring sleeve and the lower shock ring sleeve are matched with the mounting frame of the fuel pump to form a shock absorption cavity that can isolate and weaken the spread of sound, thus reducing the noise of the fuel pump assembly and functioning in noise reduction.
Description
One, technical field
The utility model relates to automobile and uses electric fuel punp, especially a kind of fuel oil pump assembly with the noise reduction chamber.
Two, background technique
Automobile uses electric fuel punp, adopts fuel pump directly to be connected with the fuel pump scaffold, and the noise that the fuel pump motor oscillating produces directly is delivered on the fuel pump scaffold, causes that the fuel oil pump assembly noise is bigger.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, adopts the fuel oil pump assembly that the band noise reduction chamber of damping ring set is housed between scaffold and the fuel pump.
Technological scheme that the purpose of this utility model adopts is, comprise that end device has scaffold, fuel pump on the oil purifier, device has fuel pump in its described scaffold frame, the fuel pump that fuel pump between fuel pump top and the scaffold is with between damping ring set, bottom and the scaffold is with down the damping ring set, forms the damping ring cavity between last damping ring set and following damping ring set and the scaffold.
The utility model, because fuel pump contacts with upper and lower shock ring cover, reduce the noise that the fuel pump vibration produces, and upper and lower damping ring set cooperates formation damping cavity with the fuel pump scaffold, can isolate, weaken the propagation of sound, thereby reduce the noise of fuel oil pump assembly, play the effect of noise reduction.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional structure schematic representation.
Among the figure: damping ring set 3-damping ring cavity 4-fuel pump 5-goes up damping ring set 6-scaffold under the 1-oil purifier 2-
Five, embodiment
As shown in drawings, comprise that end device has scaffold 6, fuel pump 4 on the oil purifier 1, device has fuel pump 4 in 6 of its described scaffolds, the fuel pump 4 that fuel pump 4 between fuel pump 4 tops and the scaffold 6 is with between damping ring set 5, bottom and the scaffold 6 is with down damping ring set 2, forms damping ring cavity 3 between last damping ring set 5 and following damping ring set 2 and the scaffold 6.
Claims (1)
1. fuel oil pump assembly with the noise reduction chamber, comprise that the last end device of oil purifier (1) has scaffold (6), fuel pump (4), it is characterized in that: device has fuel pump (4) in described scaffold (6) frame, the fuel pump (4) that fuel pump (4) between fuel pump (4) top and the scaffold (6) is with between damping ring set (5), bottom and the scaffold (6) is with down damping ring set (2), forms damping ring cavity (3) between last damping ring set (5) and following damping ring set (2) and the scaffold (6).
