Journey, baffle 2 and nozzle 1 form an aperture, and import and outlet are connected, and fast electromagnetic valve is in the open state.The solenoid valve stream
Aperture determines after amount is opened by 1 center oil-through-hole aperture of nozzle and baffle 2 and nozzle 1, when needing larger flow to export, increases
Aperture after needing to increase baffle 2 and the opening of nozzle 1 while 1 center oil-through-hole aperture of nozzle, also implies that needs increase electricity
The electromagnetic force of the movement travel of magnet valve actuation mechanism 4, the bigger electromagnet unit 8 of the trip will be smaller, it is meant that electromagnet unit 8
It needs to design bigger electromagnetic force and goes drive magnetic valve actuation mechanism 4, existing fast electromagnetic valve is not able to satisfy in same electromagnetic iron
The lower requirement for realizing big flow output of unit 8.
Summary of the invention
The purpose of the present invention: a kind of big flow is provided, nozzle-baffle arrangement that structure is simple, safe and reliable may be implemented
The opening aperture for reducing baffle and nozzle while solenoid valve big flow exports, reduces the movement travel of solenoid valve actuation mechanism,
Reduce the design difficulty of electromagnet unit.
Technical solution of the present invention: a kind of big flow nozzle-baffle arrangement, it is characterized in that: the structure includes nozzle
Component, baffle 2 and shell 5, nozzle assembly and baffle 2 are mounted in shell 5 by end face seal, and it is outer that connection is provided on shell 5
The oilhole of cavity locating for boundary and baffle, the oil outlet of nozzle assembly are ring shaped oil passage.
Preferably, the baffle 2 is provided with the oilhole being in communication with the outside at end face center position, and oilhole diameter is less than spray
Nozzle assembly ring shaped oil passage internal diameter.
Preferably, the end face center of nozzle assembly is provided with blind hole, the structural body end face between blind hole and ring shaped oil passage with
Baffle 2 forms end face seal.
Preferably, described 2 one end of baffle is connect with solenoid valve actuation mechanism 4.
Beneficial effects of the present invention: big flow nozzle-baffle arrangement proposed by the present invention has in small electric pole core
The effect of big flow output is realized under stroke, so that electromagnet unit is easier to drive, good airproof performance, structure is simple, securely and reliably,
Meet demand of the present fuel regulator to big flow.

Specific embodiment
A kind of big flow nozzle-baffle arrangement, functional structure include: nozzle assembly by porous oil nozzle 9 and nozzle carrier 10
Composition, baffle 2, spring 3, solenoid valve actuation mechanism 4, shell 5, seal washer 6, plug screw 7, electromagnet unit 8；
Porous oil nozzle 9 has Step Shaft shape, and outside is divided into 2 sections, and outer diameter is sequentially reduced from left to right, and porous oil nozzle 9 is left
There is a central blind hole 9a at end, and the blind hole bottom surface is provided with equally distributed logical oil aperture 9b and two outer circle shell of column interfaces penetrate through,
Porous 9 right side of oil nozzle has a central blind hole 9c and external cylindrical surface to form a consistent seal annulus；Nozzle carrier 10 has Step Shaft
Shape, inside center through-hole are divided into 3 sections, from left to right respectively the first cylinder hole section 10a, the second cylinder hole section 10b and third
Cylinder hole section 10c, aperture are sequentially reduced, and 10 length of nozzle carrier is identical as porous 9 length of oil nozzle；
Porous oil nozzle 9, which is inserted into the centre bore of nozzle carrier 10, forms nozzle assembly, left section of external cylindrical surface of porous oil nozzle 9 with
First cylinder hole section 10a of nozzle carrier 10 keeps tightness cooperation and is only against right side limit, and porous oil nozzle 9 and nozzle carrier 10 are left
Right both ends of the surface flush, and right section of external cylindrical surface of porous oil nozzle 9 and the third cylinder hole section inner cylinder face of nozzle carrier 10 form a ring
Shape leads to oil stream road, and circuit area is determined by logical oil stream amount；Oil liquid is from oil suction chamber through oil nozzle center porous in the nozzle assembly
Blind hole 9a, logical oil aperture 9b and the logical oil stream road of the annular are by entering oil back chamber；
Baffle 2 is boss structure, and outside is divided into 2 sections, and outer diameter is sequentially increased from left to right, 2 left end plane of baffle setting one
Central blind hole, aperture are less than the aperture right end central blind hole 9c of porous oil nozzle 9；There is a radial direction on 2 left sections of external cylindrical surfaces of baffle
Through-hole and left side central blind hole penetrate through, and 2 right side of baffle has a ball-and-socket and solenoid valve effort formation 4 inconsistent；
The baffle 2 constitutes big flow nozzle-baffle arrangement of the present invention with nozzle assembly, and solenoid valve actuation mechanism 4 is in bullet
Spring force effect under by 2 left side of baffle stop lean against the nozzle assembly right side formed end face seal, at this time oil suction chamber with go out
Oil pocket is closed, solenoid valve inlet and outlet shutdown；After electromagnet unit 8 is powered, solenoid valve actuation mechanism 4 is in electromagnetic force and baffle institute
Spring force is overcome to move right under the action of hydraulic force received, baffle 2 and the nozzle assembly form an aperture, at this time oil liquid one
Divide from the logical oil stream road of the nozzle assembly annular and flow to oil outlet chamber around, a part leads to oil stream road Xiang Zhongxin from oil liquid from annular
Oil outlet chamber is flowed to by the left end center flow channels of baffle 2, which designs the aperture for substantially reducing baffle 2 Yu nozzle assembly,
The movement travel of solenoid valve actuation mechanism 4 is reduced, so that electromagnet unit 8 is easier to drive, more secure and reliable, solenoid valve knot
Structure is also simpler, and volume is more small and exquisite, realizes that bigger flow output is wanted under the premise of meeting equivalent specifications power electromagnet iron unit
It asks.
Spring 3 is provided between baffle 2 and nozzle assembly, spring 3 play the guiding role, so that baffle 2 can be with automatic capturing
Nozzle assembly right side, baffle 2, spring 3 and nozzle assembly are sequentially loaded into shell 5, and 2 right side ball-and-socket of baffle and solenoid valve are made
Motivation structure 4 contradicts, and nozzle assembly and shell 5 are limited by boss, and are only equipped with seal washer 6 by face to guarantee that end face is close
Envelope, plug screw 7 screw in from 5 left end of shell and compress nozzle assembly.
