The generalized section that Fig. 5 is access 45, eddy current gives room 46.With the radius of the bight 45d (bight 46d) between the side 8a of the end side of spray nozzle board 8 and the side face 45b (eddy current gives the side face 46b of room 46) of access 45 for r1, when being L with the degree of depth of the bottom 45a (eddy current gives the bottom 46b of room 46) to access 45, the size of the radius r 2 of the bight 45c (eddy current gives the bight 46c of room 46) of access 45 is defined by following relation
r1＜r2＜L/2。
Spray nozzle board 8 utilizes cutting, pressure processing, etching etc. to be made, and vortex chamber 41, fuel orifice 44 are integrally formed on one block of plate.
[effect]
(flowing of fuel during valve closing)
When the coil 33 of electromagnetic coil 9 is not energized, utilizes helical spring 29 pairs of valve shafts 5 to exert a force to another side, be seated at valve seat 6 to make valve body 4.Therefore, be closed between valve body 4 and valve seat 6, fuel is not supplied to spray nozzle board 8 side.
(flowing of fuel during valve opening)
Fig. 6 is the figure recording the flowing of fuel in the stereogram of vortex chamber 41 and fuel orifice 44.
When the coil 33 of electromagnetic coil 9 is energized, electromagnetic force is utilized to overcome the active force of helical spring 29 to end side pull-up valve shaft 5.Therefore, be released between valve body 4 and valve seat 6, fuel is fed into spray nozzle board 8 side.
First the fuel being fed into spray nozzle board 8 enter central compartment 42, is transformed to radial flowing and flows into each access 45 by colliding with the bottom surface of this central compartment 42 from the flowing of axis.The tangent direction that this access 45 and eddy current give room 46 is connected, and the inner side surface therefore giving room 46 by the fuel of access 45 along eddy current rotates.
Give in room 46 at eddy current, fuel is given rotating force (eddy current power), and the fuel side with rotating force is injected along the wall portion rotation of fuel orifice 44.Therefore, the fuel sprayed from fuel orifice 44 disperses to the tangent direction of fuel orifice 44.Just utilize the rib part of fuel orifice 44 opening portion from the injected fuel spray that fuel orifice 44 is injected and be in fuel and become membranaceous liquid film state in the cone shape spray surface of general hollow.Then, membranaceous injected fuel spray starts division gradually and becomes liquidus state.Then divide further, be in the drop state that fuel fission granulates.
(reduction of dead volume)
Dead volume refers to when Fuelinjection nozzle 1 valve closing, in downstream opening portion 48, vortex chamber 41, fuel orifice 44 fuel the volume that remains.When becoming negative pressure in the intake manifold of Fuelinjection nozzle 1 burner oil, residual fuel decompression boiling, and the reason becoming that flow produces deviation relative to target fuel rate.It should be noted that, when the Fuelinjection nozzle of the high pressure of the cylinder body inner direct fuel to motor, owing to not becoming negative pressure in cylinder body, therefore usually to there is not the impact of dead volume.
In addition, fluid is usually the fastest at the immediate vicinity flow velocity of stream, and the wall flow velocity the closer to stream is slower.That is, when the bight 46c making the bight 45c of access 45, eddy current gives room 46 is formed as prismatic, because bight 45c, 46c are surrounded by wall, therefore the flow velocity of fuel is slow especially.Namely, not only near the bight 45c of access 45, that eddy current gives the contribution of the fuel that flows near the bight 46c of room 46 imperceptibility to promoting fuel is little, and near the bight 45c of access 45, eddy current give room 46 bight 46c near become the main cause that dead volume increases.
At this, in the present embodiment, make the bight 45c between the bottom 45a of access 45 and side face 45b, and the bight 46c that eddy current gives between the bottom 46a of room 46 and side face 46b is formed as R shape (curve shape) at the section of the parallel to an axis with spray nozzle board 8.
Thereby, it is possible to reduction access 45, eddy current give the volume of fuel accumulation part little to the contribution of promotion imperceptibility in room 46, cut down dead volume while fuel imperceptibility can not be affected.
[effect]
Below, the effect of the Fuelinjection nozzle 1 of mode of execution 1 is described.
Fuelinjection nozzle 1 has: valve body 4, and it is set to can open and close valve; Valve base part 7, it is formed when valve closing for the valve seat 6 that valve body 4 is taken a seat, and has downstream opening portion 48 in downstream side; Spray nozzle board 8, it is also arranged on the downstream of valve base part 7; Eddy current gives room 46, and it is formed as concavity in valve base part 7 side of spray nozzle board 8, and makes fuel rotate and give rotating force in inside; Fuel orifice 44, it is formed in eddy current and gives the bottom of room 46 and penetrate into outside; Access 45, it is formed as concavity in valve base part 7 side of spray nozzle board 8, and is communicated with the downstream opening portion 48 that eddy current gives room 46 and valve base part 7.In this Fuelinjection nozzle 1, the section shape making eddy current give the bight 46c of room 46 and the bight 45c of access 45 is curve form, the radius of section shape of the bight 46d of room 46 and the bight 45d of access 45 is being given for r1 with the side of the valve base part 7 of spray nozzle board 8 and eddy current, the radius of the section shape of the bight 46c of room 46 and the bight 45c of access 45 is given for r2 with eddy current, when the width giving room 46 and access 45 with eddy current is for W, meet relation
r2＜W/2
Ground forms eddy current and gives room 46 and access 45.
In addition, as other examples, when the degree of depth giving room 46 and access 45 with eddy current is for L, meet relation
r1＜r2＜L/2
Ground forms eddy current and gives room 46 and access 45.
Therefore, it is possible to reduction access 45, eddy current give the volume in room 46, promotion imperceptibility being contributed to little fuel accumulation part, cut down dead volume while fuel imperceptibility can not be affected.
Above, describe the present invention based on mode of execution 1, but the concrete structure of each invention is not limited to mode of execution 1, the present invention comprises the design alteration etc. of the scope not departing from inventive concept equally.
