Description
Technical field
The present invention relates to a kind of fuel pump, more particularly to a kind of high-pressure high-flow environmental protection integration electric fuel pump device.
Background technology
Fuel pump is the technical term of auto parts machinery industry.It is one of the basic composition of electro jet car fuel injection system.
Effect is that fuel oil is transported to after being sucked out, pressurizeing in fuel tank in fuel feed pump to connect with atomizer.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 installed for blade
At.
In more special operating mode, 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 at conduit easily goes out
It now reveals, pressure transient.And fuel pump needs continue working, and not so its charge oil pressure will appear wild effect.Not only
More consume energy, it is larger to the wasteness of resource, and also the service life of fuel pump is shorter, easily breaks down.
Invention content
It can be intermittent in view of the deficiencies of the prior art, the present invention provides a kind of big flow, pressure stability, fuel pump

Channel is flowed towards fuel oil delivery outlet, at this point, for energy saving and extension fuel pump service life, it can be by controller to fuel oil
Pump is implemented to close.Such setting is not only energy saving, but also environmental protection.
The present invention is further arranged to：Integrated housing is in tubbiness, the placement space laid out in parallel in integrated housing,
The fuel pump being respectively in placement space is parallel with one another, has mutually isolated isolation inner wall between each placement space, collects shelling
Axial one end of body is the installation end that can be positioned over fuel pump in placement space, and the other end is blind end, is set at installation end
There are the capping being tightly connected with integrated housing, the fuel oil input port to be set to the bottom side of integrated housing, fuel oil delivery outlet
The other side at the top of integrated housing.
Using above-mentioned technical proposal, by placement space laid out in parallel in integrated housing, it can not only make the row of placement space
Cloth is reasonable, and can effectively utilize the structure of integrated housing, and more placement spaces can be arranged under limited volume.
The present invention is further set as：It is equipped with the exhaust be connected respectively with each placement space at integrated housing isolation inner wall
Channel, exhaust passage is interior to be equipped with check valve.
Using above-mentioned technical proposal, 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 present invention is further set as：Check-valves includes the valve body being set up in nature oil supply gallery, and valve body includes
There are fuel oil upstream end and fuel oil output end, fuel oil upstream end to be arranged towards fuel oil input port, fuel oil output end is defeated towards fuel oil
Outlet setting, and being equipped at the fuel oil upstream end of valve body can promote fuel oil upstream end to be connected with fuel oil input port or closed sealing
Spool, fuel oil output are equipped with positioning seat, and positioning seat is equipped with and is connect with sealed valve core and can be along fuel oil upstream end and fuel oil
Output end is equipped with compressed spring toward the valve rod of polyslip between sealed valve core and positioning seat.
Using above-mentioned technical proposal, such setting structure is simple, convenient for disassembly and assembly.
The invention will be further described below in conjunction with the accompanying drawings.
