Length direction on extend.As shown in Fig. 2 rib 65 occupying space and formed along fuel pump 31.Drawn between rib 65
Separate above-mentioned path 64.Pump case 13 is formed as the drum coaxial with the cylinder 32 of fuel pump 31.
Simply illustrate the assemble method of fuel pump module 12.Prepare the 1st housing parts 51, the 2nd housing parts 52 and
Fuel pump 31.Pressure regulator valve 58 is assembled in the 2nd housing parts 52.As long as the 1st housing parts 51 and the 2nd housing parts 52 are by resin
Material is molded.The press-in pipe 35 of fuel pump 31 is pressed into the connection stream 36 of the 1st housing parts 51.Now, fuel pump
31 are guide by rib 65 and are inserted into the 1st housing parts 51.Therefore, the press-in pipe 35 of fuel pump 31 can readily enter the 1st
In the connection stream 36 of housing parts 51.The 1st housing parts are so maintained at by the fuel pump 31 for being pressed into pipe 35 and being pressed into
In 51.
Then, make the 2nd housing parts 52 chimeric with the 1st housing parts 51.As long as in the 1st housing parts 51 and the 2nd housing
Mutually chimeric concaveconvex shape is formed with the composition surface of part 52.2nd housing parts 52 exist towards the 1st housing parts 51
The chimeric side parallel with rotary shaft 45 moves up.Connecting tube 39 is entered in the connection stream 41 of the 2nd housing parts 52.Even
Seal member 42 is equipped with adapter 39 in advance.When the composition surface of the 1st housing parts 51 and the 2nd housing parts 52 is against each other
When, composition surface is subjected to welding around accommodation space 53 on complete cycle.
In fuel pump module 12, fuel pump 31 is stored in accommodation space 53.Corresponding to welding, in the 1st housing parts
Good sealing is established between the open end 55 of 51 housing parts 52 of open end 54 and the 2nd.Moreover, such being formed
Fusion bonding process is used during construction.In fusion bonding process, fuel pump 31 is kept on the 1st housing parts 51.Realize fuel pump 31
Positioning and the combination of the 1st housing parts 51 and the 2nd housing parts 52.Reduce manufacturing process.Reduce manufacturing cost.
In the assembling of fuel pump module 12, the 1st housing parts 51 and the 2nd housing parts 52 are be combined with each other.Now, when
When 2nd housing parts 52 are moved up relative to the 1st housing parts 51 in chimeric side, abutted each other between open end 54,55, together
When, the connecting tube 39 of fuel pump 31 is inserted into the connection stream 41 of the 2nd housing parts 52.1st He is realized by 1 action
The combination of 2nd housing parts 51,52 and the 2nd housing parts 52 and fuel pump 31 it is chimeric.Reduce manufacturing process.Reduce
Manufacturing cost.
Press-in pipe 35 is formed with fuel pump 31 in fuel pump module 12.Press-in pipe 35 is fixed on by press-in
In the connection stream 36 marked off in 1st housing parts 51.Fuel pump 31 is reliably fixed to the 1st housing parts 51.
In fuel pump module 12, connecting tube 39 is formed with fuel pump 31.The sliding freely company of insertion of connecting tube 39
Connect in stream 41.Therefore, even if the 1st housing parts 51 or the 2nd housing parts 52 produce the deviation of dimensional accuracy or based on combustion
Being swelled for material and cause the 1st housing parts 51 and the 2nd housing parts 52 to produce the variation of size, corresponding to connecting tube 39 relative to
The sliding action of stream 41 is connected, the deviation of size or variation can also be absorbed.Moreover, being equipped with the periphery of connecting tube 39 close
Seal part 42.Sliding action regardless of connecting tube 39, seal member 42 all remains fluid tight.
Rib 65 is formed with the inner surface connected with accommodation space 53 of the 1st housing parts 51.By the effect of rib 65
And improve the rigidity of the 1st housing parts 51.Therefore, the shaping in the 1st housing parts 51 or the 1st housing parts 51 and the 2nd shell
During the welding of body component 52, the deformation of the 1st housing parts 51 is inhibited to greatest extent.Rib 65 is additionally, since in fuel pump 31
Length direction on it is spatially extended along occupying for fuel pump 31, therefore, in weld job, rib 65 can be in the 1st housing section
Fuel pump 31 is kept in part 51.Improve operating efficiency.
In fuel pump module 12, the accommodation space 53 closed by welding is used as the fuel discharged from degassing orifice 48
Path 64.The construction of fuel pump module 12 is simplified.On this basis, the vibration of fuel pump 31 and sound are limited in logical
Cross welding and in closed accommodation space 53.Inhibit vibration and the leakage of sound.
In the above embodiment, the press-in pipe 35 of fuel pump 31 is pressed into the 1st housing parts 51, in the 2nd housing
Connecting tube 39 is sliding freely inserted in part 52, but it is also possible to will be pressed into the 2nd housing parts 52 that pipe 35 is pressed into cap-shaped shape
