Detailed description of the invention
Carry out the preferred embodiment that the present invention will be described in detail below in reference to attached drawing.It is shown in attached drawing:
Fig. 1 is according to an embodiment of the invention to be directly blown into formula gas injector schematically cuing open in the closed state
View.
Specific embodiment
The gas injector 1 of first preferred embodiment according to the present invention is described in detail below in reference to Fig. 1.
As shown in Figure 1, gas injector 1 includes valve closing element 2, it is in the present embodiment needle.X-X is marked herein
The axial direction of gas injector.Valve closing element 2 discharges pass through openings 3, which is arranged in sealing shroud in the present embodiment
In pipe 6.
As shown in Figure 1, sealing sleeve pipe 6 is the sleeve element with set region 60 and bottom 61, wherein pass through openings 3 are constituted
In bottom 61.In addition, being additionally provided with taking towards inside for the end opposite with pass through openings 3 of sealing sleeve pipe 6 in sealing sleeve pipe 6
To annular stop portion 62.
Gas injector 1 further includes being constructed in a known way with the Electromagnetically actuated of armature 50, coil 51 and interior pole 52
Device 5.Alternatively, it is possible to use piezo actuator.
Armature 50 connect with valve closing element 2 herein and makes it possible to valve closing element 2 when coil 51 is powered from the
One seal receptacle 11 lifts.
As shown in Figure 1, the first seal receptacle 11 is arranged between valve closing element 2 and sealing sleeve pipe 6 in pass through openings 3 herein
On.
Second seal receptacle 12 is arranged between sealing sleeve pipe 6 and valve body 4.Valve body 4 itself has multiple spray-holes 9.
On valve closing element 2 also constitute take portion 20, after the predetermined free travel F that passes by with sealing
The stopper section 62 of casing 6 contacts.Thus can make to seal after the free travel F that passes by the opening procedure of valve closing element 2
Casing 6 also moves.
Here, sealing sleeve pipe 6 is pre-tightened by the direction of the first spring element 18 towards the combustion chamber of internal combustion engine 10.
In addition, being provided with third seal receptacle 13 between sealing sleeve pipe 6 and valve body 4.Third seal receptacle 13 is nonelastic body
Seal receptacle and preferred tool there are two the sealing mating members of metal.
In addition, being fixed with positioning disk 15 in valve body 4 for guiding valve closing element 2.It is provided in positioning disk 15 more
A hole 17 for allowing fuel gas to pass through.Valve closing element 2 is guided on the guiding area 16 of positioning disk 15.
Valve closing element 2 is also pre-tightened by second spring element 19 towards combustion chamber direction.Positioning disk 15 is simultaneously with effect
In the spring base of the first spring element 18.First seal receptacle 11 includes the first elastomer element 31, is arranged in the present embodiment
In sealing sleeve pipe 6.Second elastomer element 32 is arranged on the second seal receptacle 12, wherein being provided with court in sealing sleeve pipe 61
Externally-oriented flange 63, the flange seal on the second elastomer element 32.
The first diameter D1 of first seal receptacle 11 is herein less than the second diameter D2 of the second seal receptacle 12.In addition, in combustion gas
It is provided with after sealing sleeve pipe 6 on the circulating direction of injector 1 pressure equalizing chamber 7 (referring to Fig. 1).Pressure equalizing chamber 7 is located at
Between sealing sleeve pipe 6 and the combustion chamber side end of valve body 4.Spray-hole 9 in valve body 4 is arranged so in valve body herein, so that
Simply existing into the flow path of each spray-hole 9 there are restricted flow path 8 or only respectively from pressure equalizing chamber 7
Gap.
Here, the working method of gas injector 1 according to the present invention is as described below.When being blown into for implementation fuel gas
When, electromagnetic actuators 5 are activated and armature 50 is attracted to the interior pole 52 of electromagnetic actuators.It is permanently connected as a result, with armature 50
Valve closing element 2 lifted from the first seal receptacle 11 and discharge pass through openings 3.Fuel gas may pass through sealing sleeve pipe 6 as a result,
Inside from by valve closing element 2 by being flowed into pressure equalizing chamber 7 across pass through openings 3.
Due to the throttle point generated by the restricted flow path 8 between pressure equalizing chamber 7 and spray-hole 9, in pressure balance
The horizontal approximately equal pressure water of gaseous fuel pressure before predetermined and pass through openings 3 is rapidly established in room 7
It is flat.The pressure balance being achieved in the region of the combustion chamber side end of valve closing element 2 expends so as to not big power
The further opening procedure of ground progress valve closing element 2.Therefore in opening, valve closing element 2 is temporary pressure balance
's.In the closed state, the system pressure of fuel gas assists the valve closing element of opening type inwardly in seal aspect.
Valve closing element 2 is arranged in this section in sealing sleeve pipe 6.
Because the first diameter D1 of the first seal receptacle 11 is relatively small, it can be expended and close valve with relatively small power
Element 2 is lifted from the first seal receptacle 11.
Therefore according to the present invention, by the way that restricted flow path 8 is arranged, burn in opening procedure by the direction of sealing sleeve pipe 6
The pass through openings 3 between the side of combustion chamber of the side of room and sealing sleeve pipe 6 pressure equalizing chamber 7 and spray-hole 9 it
Between obtain the pressure difference for effectively playing pneumatic action.It is possible thereby to after the free travel F that passes by equally with small power expend into
One step attracts sealing sleeve pipe 6 in the direction of arrow A, so that at this moment there is the big cross for being used to for combustion gas being sent to spray-hole 9
Section, wherein the throttle point on restricted flow path 8 is increasingly widened with the movement (arrow B) of sealing sleeve pipe 6, until the throttling
Position completely disappears and there is no throttling actions.
Therefore, a kind of combustion for fuel gas to be directly blown into combustion chambers of internal combustion engines can be provided according to the present invention
Gas blowout emitter has the very short response time for open and close.In addition, guaranteeing gas injection by the way that multiple seal receptacles are arranged
The high leakproofness of emitter 1, wherein sealing sleeve pipe 6 is pressed in the second seal receptacle 12 and third seal receptacle by the high pressure of especially fuel gas
In 13.Third seal receptacle 13 also serves as the stopper section of the return stroke of limit sealing sleeve pipe 6 herein.Here, combustion gas of the invention
Injector has structure that is compact and can cost-effectively manufacturing without complicated component, so that the gas injector is outstanding
It is suitable for batch micro operations.
In addition, according to the present invention, gas injector 1 can be by the various configuration of the length of free travel F come relatively easy
Ground requires to adjust with actual conditions for the difference that fuel gas is directly blown into.
