Description
Technical field
The utility model relates to a kind of fuel pump, in particular to a kind of collection of high-pressure high-flow integration electric fuel oil pump assembly
At shell.
Background technique
Fuel pump is the technical term of automobile parts industry.It is one of the basic composition of electro jet car fuel injection system.
Effect is that fuel oil is transported in fuel feed pump to connect with atomizer after being sucked out, pressurizeing in fuel tank.Fuel pump is with diesel oil and vapour
Oil is working media.Traditional fuel pump is mainly by shell, the oil inlet on shell, oil outlet and in shell
Rotor, the stator for being sheathed on outer casing inner wall and being adapted to rotor, the blade to link with rotor and the pedestal group for blade installation
At.
In more special operating condition, in order to improve the pressure and flow of fuel system, it will usually by several fuel pumps
Implement to connect by plastic catheter, such mode is connected using conduit, and not only connection procedure is relatively complicated, but also easily goes out at conduit
It now reveals, pressure transient.Therefore, how several fuel pumps to be implemented to connect, and can guarantee its leakproofness and pressure
Stability is always the problem that field technical staff can not overcome.
Summary of the invention
In view of the deficienciess of the prior art, the utility model provides, one kind is easy to assembly, is less prone to leakage, sealing
The integrated housing of stable high-pressure high-flow integration electric fuel oil pump assembly.
To achieve the above object, the utility model provides following technical solution: a kind of high-pressure high-flow integration electric combustion
The integrated housing of oil pump assy, it is characterised in that: include shell and lid connected to the housing, have on shell for several
The placement space of fuel pump placement positioning and the fuel oil input port be connected with placement space and fuel oil delivery outlet are set in placement space
There is the interface channel for the connection of each fuel pump.
By adopting the above technical scheme, several fuel pumps are placed in shell by placement space, and each fuel pump is logical
It crosses interface channel and implements connection, setting is not only easy to assembly in this way, but also promotes to be placed between the intracorporal each fuel pump of shell
It connects without directlying adopt channel connection by conduit, channel can both realize connection, eliminate due to sealing not when conduit connection
The case where stable defect, not only good airproof performance is not in leakage, and stabilize pressure when each fuel pump is connected with each other
Power.
The utility model is further arranged to: placement space laid out in parallel has phase in shell between each placement space
Axial one end of the isolation inner wall being mutually isolated, shell is the installation end that can be placed in fuel pump in placement space, and the other end is
The installation end of closed end, the lid and placement space is tightly connected, and fuel oil input port is set to the bottom side of shell, fuel oil
Delivery outlet is set to the other side of case top.
By adopting the above technical scheme, by placement space laid out in parallel in integrated housing, the row of placement space can not only be made
Cloth is reasonable, and can effectively utilize the structure of integrated housing, settable more placement spaces under limited volume.
The utility model is further set to: being equipped with the exhaust be connected respectively with each placement space at shell isolation inner wall
Channel, exhaust passage is interior to be equipped with check valve.
By adopting the above technical scheme, the gas in integrated housing can be discharged for the setting of exhaust passage internal check valve, but can
Prevent external gas or medium from entering in integrated housing.
The utility model is further described with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of shell in the utility model embodiment；
Fig. 2 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
It include shell such as a kind of Fig. 1-integrated housing of high-pressure high-flow integration electric fuel oil pump assembly shown in Fig. 2
1 and the lid 2 that is connect with shell 1, have for the placement space 11 of several fuel pump placement positionings on shell 1 and empty with placing
Between 11 conductings fuel oil input ports 12 and fuel oil delivery outlet 13, the interface channel for the connection of each fuel pump is equipped in placement space 11
14.By adopting the above technical scheme, several fuel pumps are placed in shell 1 by placement space 11, and each fuel pump passes through
Interface channel 14 implements connection, and setting is not only easy to assembly in this way, but also promotes between each fuel pump being placed in shell 1
It connects without directlying adopt channel connection by conduit, channel can both realize connection, eliminate due to sealing not when conduit connection
The case where stable defect, not only good airproof performance is not in leakage, and stabilize pressure when each fuel pump is connected with each other
Power.
In the utility model embodiment, 11 laid out in parallel of placement space has between each placement space 11 in shell 1
Mutually isolated isolation inner wall 15, axial one end of shell 1 are the installation end that can be placed in fuel pump in placement space 11, separately
One end is closed end, and the installation end sealed connection of lid 2 and placement space 11, fuel oil input port 12 is set to the bottom side of shell 1
Portion, fuel oil delivery outlet 13 are set to the other side at 1 top of shell.By 11 laid out in parallel of placement space in integrated housing 1, not only
The arrangement of placement space 11 can be made reasonable, and can effectively utilize the structure of integrated housing 1, it is settable under limited volume
More placement spaces 11.Shell 1, which is isolated at inner wall 15, is equipped with the exhaust passage 16 with the conducting of each placement space 11 respectively, exhaust
Check valve 3 is equipped in channel 16.The gas in shell 1 can be discharged for the setting of check valve 3, but can prevent external gas or Jie
Matter enters in shell 1.
