It is inserted by connection in the bellmouth of valve supporting member.Supporting member is presented in the reception recess portion of braced frame, to press
Force regulating valve door is maintained in the bellmouth of valve supporting member.Therefore valve is fixed, to prevent because of the pressure on fuel circuit
Caused any movement.
Therefore, the solution presented through the invention, the element of existing fuel pump unit have received new fixation function
Can, and therefore can save the use of additional fixing element.Valve support component corresponding to manifold present in fuel pump unit
In addition to the coupling part for being inserted into pressure-regulating valve door, it is also integrated with guiding and fixing element.It is existing to receive fuel
The braced frame of pump is integrated with recess portion and joint element, and there are support components in recess portion so that valve to be held in place,
The joint element is to fixed valve supporting member.
Detailed description of the invention
The one embodiment now presented based on attached drawing is come the present invention will be described in more detail.Attached drawing is shown:
Fig. 1 is the schematic diagram of the device of the invention；
Fig. 2 is the exploded view of the device of the invention；
Fig. 3 is the figure for showing the valve supporting member being inserted into the device of the invention；And
Fig. 4 is the figure for being shown affixed to the valve supporting member of the device of the invention.
Specific embodiment
As shown in Figure 1, the fuel system of motor vehicle especially includes internal combustion engine 1, and wherein internal combustion engine 1 is from petrolift list
Member receives fuel.In this element, petrolift 2 pressurizes to the supply connection for being connected to manifold.Supply connection is extended to from manifold
Internal combustion engine 1 and towards be mounted on filling container in jet pump 3 route.Fuel passes through the fuel stream across jet pump 3
It is directly sucked in from fuel tank into filling container.Connector towards the return line of internal combustion engine 1 exists in manifold.Pressure tune
It saves valve 5 to install close to the connector, and when reaching given pressure, the flowing of fuel return line is discharged into filling container
In.
In an embodiment of the present invention, manifold, which has, is fixed on the additional functionality in its position, discrimination for pressure-regulating valve door
Pipe is hereinafter referred to as valve supporting member 6.
There is valve supporting member 6 first connector 6a of the return line for receiving internal combustion engine, reception to supply derived from the fuel of pump 2
It answers the second connector 6b of route, fuel supply connection is connected to the third connection line 6c of internal combustion engine, and is last, connect
Towards the 4th connector 6d of the route of jet pump 3.Valve supporting member 6 is inserted in the recess portion 8 of braced frame 4.This support frame
Frame 4 also receives petrolift 2, and is inserted into the filling container of fuel tank.Third connector 6c alternatively includes check-valves, with
When petrolift 2 is turned off, prevent fluid from returning to the fuel supply connection of internal combustion engine 1.
Holding member 13 extends in vertically downward direction from recess portion 8, and for receiving pressure-regulating valve door 5, wherein pressing
Shoulder 14 of the force regulating valve door 5 against the end of holding member 13.Therefore, holding member 13 with valve supporting member 6 together
With the function being fixed on pressure-regulating valve door 5 in its operating position, thus stablized, to prevent the behaviour because of fuel system
Make any movement of due to pressure.
In the exploded view of Fig. 2, valve support component 6 can with its first connector 6a, the second connector 6b, third connector 6c and
4th connector 6d is identified.Valve supporting member 6 have the function of being secured to pressure-regulating valve door 5 it is associated, with first
The bellmouth 6e that connector 6a is fluidly connected, wherein valve coupling part 5a is inserted into bellmouth 6e.This coupling part 5a includes sealing
Ring, to ensure the compactness coupled.Valve supporting member 6 further include be secured to valve 5 function is associated, outside has
The coupling member 7 of "T"-shaped shape.The coupling member 7 will be with Profile Connection (positive coupling) and braced frame 4
On counterpart member engagement.Valve supporting member 6 and its as manifold function in association, in the opposite end of coupling member 7
Place has cap 15, to be sealed to it.When valve supporting member 6 is inserted into recess portion 8, the cap 15 is against support frame
Frame 4 therefore ensures that its sealing.The seal cap 15 can be connected through a screw thread or weld and be attached to valve supporting member 6.
Assembling sequence and required component for pressure-regulating valve door 5 to be fixed to fuel pump unit is also shown in Fig. 2
Number.In the presence of only two assembling steps and comprising three components including valve, this is very big advantage compared with prior art.Valve
Door 5 is firstly inserted into valve supporting member 6, and the union end 5a of valve 5 is inserted into bellmouth 6a.Then, including valve branch
The assembly of support component 6 and valve 5 is placed in the recess portion 8 of braced frame 4.Valve 5, opposite with union end 5a side
Therefore it is inserted into holding member 13, makes its end against at least one shoulder 14.
From Fig. 2, it will be clear that, as already explained, pressure-regulating valve door 5 is placed on valve supporting member 6, so that only in valve
When door supporting member 6 is inserted into recess portion 8, pressure-regulating valve door 5 is introduced.At least one shoulder 14 and valve of holding member 13
The distance between fixation position of support component 6 corresponds to pressure-regulating valve door 5, prominent from the bellmouth 6e of valve supporting member 6
The length for the part risen.
Final step in Fig. 3 in the visible recess portion that valve supporting member 6 is inserted into braced frame 4." T " shaped company
Structural member 7 is engaged with " T " shaped slot 12, so that offer type face male and female type (positive male-female type) connects, it should
Connection stablizes valve supporting member to resist torsion movement and lateral movement.At the end of stroke of the coupling member in slot 12
End, at least one the holding shoulder 14 of valve 5 against holding element 13.In addition, the end of the stroke in coupling member 7 in slot 12
End, cap 15 will be against braced frame 4.
The shoulder 10 around valve supporting member 6 is also shown in Fig. 3.The shoulder 10 is for keeping valve supporting member 6
In its position with resist the due to pressure acted on valve 5 by fuel system it is vertically movable for be important.
Finally, valve supporting member 6 stands upright on its final position in Fig. 4, be installed into be located at supporting member 6,
Stop part 11 of the shoulder 10 for the end arranged close to the first connector 6a in braced frame 4.In addition, in braced frame 4
Coupling member 9a and 9b is formed by after valve supporting member 6 is by them, is made on two sides in the region of connector 6b
For shoulder 10.Coupling member 9a and 9b can be one or more components for any position being arranged near shoulder 10,
Any upward vertically movable to prevent, stop part 11 prevents any downwardly vertical movement of valve supporting member 6.
The example that preferred embodiment has been described, it must be understood that, the scope of the present invention includes other possible variations, and
Only limited by the content of appended claim and possible equivalent wherein included.
