Abstract
A kind of high pressure co-rail diesel prefilter, including shell, filter core, the oil-out and oil inlet for being arranged on shell upper and lower ends, filter core is arranged in shell, include cavity in filter core, mozzle is provided with cavity in filter core, mozzle upper end is tightly connected with oil-out, and mozzle lower end is located at below pasta and extends to filter core bottom.Mozzle upper end is sealedly connected on oil-out by the high pressure co-rail diesel prefilter, lower end is arranged at below fuel level, the air being effectively isolated by mozzle in prefilter, reduce the gas into combustion system, and can makes fuel oil rapidly enter engine, it has been effectively ensured the normal startup of engine, it is simple in construction, be easily achieved.
Description
Technical field:
Mechanical field, more particularly to fuel filter technology, more particularly to fuel oil prefilter are the utility model is related to, specifically
It is a kind of high pressure co-rail diesel prefilter.
Background technology:
The major function of diesel oil prefilter is to filter out granule foreign relatively large in diesel oil, while is separated in diesel oil
Moisture, certain air is had after engine stop works and is entered in prefilter so that pasta declines inside prefilter, works as hair
When motivation is again started up, the air in prefilter can be first into combustion system by oil-out, cause engine to occur
Need the situation that repeatedly starts or can not start.
The content of the invention：
The purpose of this utility model is to provide a kind of high pressure co-rail diesel prefilter, described this high pressure co-rail diesel
Prefilter, the air that to solve diesel oil prefilter in the prior art can not effectively obstruct in prefilter enter combustion system and cause to send out
The technical problem that motivation can not start.
This diesel oil prefilter for high pressure co-rail system of the present utility model, including shell, filter core, be arranged on it is described
The oil-out and oil inlet of shell upper and lower ends, described filter core are arranged in shell, and cavity is included in filter core, wherein, institute
State and mozzle is provided with the cavity in filter core, the mozzle upper end is tightly connected with the oil-out, the mozzle lower end
Below pasta and extend to the filter core bottom.
Further, the mozzle upper end is joint for sealing connecting, is set between the joint for sealing connecting and the oil-out
There is sealing ring.
Further, the mozzle is pipe.
Operation principle of the present utility model is：Mozzle upper end is arranged on prefilter oil-out by joint for sealing connecting
On, lower end is arranged in prefilter position below pasta, and air enters in prefilter after engine stop work, by being arranged on
Draft tube structure in filter core inner chamber, isolate air in prefilter and enter combustion system, after engine start, pass through mozzle knot
Structure, fuel oil are rapidly entered in combustion system.
The utility model compares with prior art, and its effect is positive and obvious.The utility model is by mozzle
End is sealedly connected on prefilter oil-out, and lower end is arranged at below fuel level, is effectively isolated by mozzle in prefilter
Air, reducing into the gas in combustion system, and can makes fuel oil rapidly enter engine, and engine has been effectively ensured
It is normal to start, it is simple in construction, be easily achieved.
Brief description of the drawings：
Fig. 1 is overall structure diagram of the present utility model
Embodiment：
Embodiment 1:
As shown in figure 1, the diesel oil prefilter of the present utility model for high pressure co-rail system, including shell 1, filter core 2, set
Put the oil-out 4 and oil inlet 5 in the upper and lower ends of shell 1, be provided with mozzle 3 in filter core in 2 cavity, the upper end of mozzle 3 with
Oil-out 4 is tightly connected, and the lower end of mozzle 3 is located at pasta and extended below to the bottom of filter core 2.
Further, the upper end of mozzle 3 is joint for sealing connecting 6, and sealing ring is provided between joint for sealing connecting 6 and oil-out 4
7, effective sealing mechanism is formed, prevents air from entering in mozzle 3.
Further, mozzle 3 is pipe.
The working method of the present embodiment is：The upper end of mozzle 3 is arranged on prefilter oil-out 4 by joint for sealing connecting 6,
Lower end is arranged in prefilter position below pasta, has partial air to enter in prefilter after engine stop work, leads to
The structure of mozzle 3 being arranged in the inner chamber of filter core 2 is crossed, isolates air in prefilter and enters combustion system, after engine start,
By the structure of mozzle 3, fuel oil can be rapidly introduced into combustion system, realize the normal startup of engine.
