Description
Technical field
The present invention relates to a kind of high-pressure fuel pumps, for example, the fuel system for internal combustion engine high-pressure fuel pump, the fuel
There is high-pressure pump pump case and the attachment being assemblied on the outer surface of pump case arched upward to take over, and be taken over by the attachment, fluid
It can be flowed into pump case or be flowed out by pump case.
Invention content
The problem of the present invention is solved by high-pressure fuel pump according to the present invention.The present invention also proposes advantageous extension side
Formula.
The present invention is from following demand:It will take over and fix and enduringly but simultaneously with the consuming of few manufacturing technology
It is arranged on the outer surface of pump case arched upward.
In addition, the present invention is based on following cognitions:In order to take over fixed by the outer surface of pump case arched upward and attachment and hold
It connects long, needs to take over not only in the hole of pump case in, and be fixed on the outer surface of pump case arched upward
On so that it takes over and not only needs for example cylindrical region, which takes over can be by the cylindrical region in pump case
The hole in centering, and need the region for example arched upward, which, which takes over, to be fixed on pump by the region arched upward
On the outer surface of shell arched upward.Inventor identified, complicated in this member principle and can only manufacture bothersomely,
But solution can be obtained according to the present invention.
It proposes in the present invention, implements and there is the first sleeve-shaped component and second sleeve to attachment take over multiple piece
Shape component, first sleeve-shaped component make attachment take in the hole of pump case in, and the second sleeve shape component makes attached
Take on the outer surface arched upward for being fixed on pump case, by this way, can be manufactured with few consuming the two have compared with
The sleeve-shaped component of simple geometry and it can be assembled by known method on high-pressure fuel pump.It is overall
On, it will take over fixed and enduringly but be simultaneously arranged in the outer surface of pump case arched upward with few manufacturing technology consuming
On.
Take over can more particularly to high-pressure fuel pump fuel entrance, high-pressure fuel pump can be entered by the fuel
Portion and the area of low pressure of fuel system, such as low-lift pump connect.On the other hand, take over can also be high-pressure fuel pump row
Go out portion, especially compressed fuel leaves the pump further through the discharge unit.By a discharge unit, fuel leaves pump and does not have in itself
Have compressed in pump and/or fuel for example constitute leakage or fuel for example for flushing pump, which also especially constitutes institute
Attachment is stated to take over.
It is clear that taking on all sides that can be easily positioned on pump case, especially in the Gai Yuan of pump case
On all sides of part, such as in the radial side and/or axial side of pump case or cap member.
Sleeve-shaped component is especially appreciated that for a component, which is can flowing and/or outstanding in the scope of the application
The shape of its shape with annular disk or the pipe fitting with cylindricality and/or bending.Sleeve-shaped component can especially have circle
Outer periphery and/or inner periphery.
