In this way, the utility model discloses can avoid the diesel oil savings to be bored with in the pressure chamber of diesel engine fuel sprayer, improve diesel engine fuel sprayer oil spout efficiency, further promote the stable quality of diesel engine fuel sprayer.
Description
Technical field
This utility model relates to diesel engine arts, particularly relates to a kind of oil removal diesel engine atomizer.
Background technology
The atomizer of automobile is exactly a simple electromagnetic valve in fact now, when the solenoid is activated, produces suction, and needle-valve is picked up, and opens spray orifice, the ejection at a high speed of fuel oil annular gap between the axonometer and spray orifice of needle-valve head, is formed vaporific, is beneficial to burning fully.The atomizer of use for diesel engine was Mechanical course in the past, and mechanical type diesel fuel nozzle realizes work by controlling precision pair.The couple of nozzle is one of big precision pair of conventional diesel engine three, three big precision pairs: plunger, plunger bushing, needle-valve, needle-valve body, delivery valve, delivery valve seat.Gasoline engine nozzle is a part for Gasoline Engine Electronic Control System, replaces the carburetor of carburetor gasoline engine.The nozzle of automobile mainly has: diesel fuel nozzle, petrol jet, natural gas nozzle etc., some the most external manufacturer can manufacture hydrogen special nozzle.But atomizer during life-time service can by diesel oil greasy live blocking, general diesel oil can greasy live atomizer pressure accumulation chamber and nozzle location, but little more next than pressure accumulation chamber of nozzle, it is impossible to design corresponding device to eliminate diesel oil blockage problem.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of oil removal diesel engine atomizer, it is possible to avoids diesel oil savings greasy in the pressure accumulation intracavity of diesel injector, improves diesel injector oil spout efficiency.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of oil removal diesel engine atomizer, including needle-valve and needle-valve housing, described needle-valve imports and is socketed in described needle-valve housing, described needle-valve includes liquid guiding cavity, pressure accumulation chamber, spray chamber, cool down chamber and nozzle, described liquid guiding cavity is located at described needle-valve enclosure interior front end, described liquid guiding cavity rear end connects described pressure accumulation chamber, it is fixed with two ball bodies on the chamber of two ends, described pressure accumulation chamber, described pressure accumulation cavity rear end sprays chamber described in connecting, the described chamber end that sprays connects the described nozzle of installation.
In one preferred embodiment of this utility model, described ball body is fixed in the chamber of described pressure accumulation chamber by pin, and described ball body rotates around described pin.
In one preferred embodiment of this utility model, described liquid guiding cavity chamber width is less than described pressure accumulation chamber chamber width.
In one preferred embodiment of this utility model, described pressure accumulation chamber is flattened round chamber.
The beneficial effects of the utility model are: this utility model, it can be avoided that diesel oil savings is greasy in the pressure accumulation intracavity of diesel injector, improves diesel injector oil spout efficiency, improves the property stability of diesel injector further.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of this utility model oil removal diesel engine atomizer one preferred embodiment；
In accompanying drawing, the labelling of each parts is as follows: 1, needle-valve；2, needle-valve housing；3, liquid guiding cavity；4, pressure accumulation chamber；5, chamber is sprayed；6, cool down chamber；7, nozzle；8, ball body；9, pin.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of oil removal diesel engine atomizer, including needle-valve 1 and needle-valve housing 2, described needle-valve 1 imports and is socketed in described needle-valve housing 2, described needle-valve 1 includes liquid guiding cavity 3, pressure accumulation chamber 4, sprays chamber 5, cool down chamber 6 and nozzle 7, described liquid guiding cavity 3 is located at described needle-valve housing 2 interior forward end, described liquid guiding cavity 3 rear end connects described pressure accumulation chamber 4, it is fixed with two ball bodies 8 on the chamber of two ends, described pressure accumulation chamber 4, rear end, described pressure accumulation chamber 4 sprays chamber 5 described in connecting, described in spray chamber 5 end and connect described nozzle 7 is installed.
It addition, described ball body 8 is fixed in the chamber of described pressure accumulation chamber 4 by pin 9, described ball body 8 rotates around described pin 9.
It addition, described liquid guiding cavity 3 chamber width is less than described pressure accumulation chamber 4 chamber width.
It addition, described pressure accumulation chamber 4 is flattened round chamber.
nullOperation principle of the present utility model is socketed in needle-valve housing 2 for being imported by needle-valve 1，Needle-valve 1 includes liquid guiding cavity 3、Pressure accumulation chamber 4、Spray chamber 5、Cool down chamber 6 and nozzle 7，Liquid guiding cavity 3 is located at needle-valve housing 2 interior forward end，Liquid guiding cavity 3 rear end connects pressure accumulation chamber 4，Liquid guiding cavity 3 chamber width is less than pressure accumulation chamber 4 chamber width，Pressure accumulation chamber 4 is flattened round chamber，It is fixed with two ball bodies 8 on the chamber of two ends, pressure accumulation chamber 4，Ball body 8 is fixed in the chamber of pressure accumulation chamber 4 by pin 9，Ball body 8 rotates around pin 9，The connection of rear end, pressure accumulation chamber 4 sprays chamber 5，Spray chamber 5 end and connect installation nozzle 7，Diesel oil is through atomizer，First pass through the liquid guiding cavity 3 of needle-valve 1，Then flow through pressure accumulation chamber 4，Owing to ball body 8 is installed at two ends, pressure accumulation chamber 4，Make the diesel oil will not greasy situation about resulting in blockage in pressure accumulation chamber 4，Then diesel oil is through spraying chamber 5 and chamber 6 of cooling down，Finally spray from nozzle 7，Owing to the ball body 8 in pressure accumulation chamber 4 can effectively prevent diesel oil savings greasy firmly，Improve diesel injector oil spout efficiency，Improve the property stability of diesel injector further.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
