Magnetic sheath, is configured in described coil block;
Armature, to be arranged in described magnetic sheath and to move vertically under the electromagnetic force produced at winding coil;
The valve pocket be positioned at above spool has a spiracle, described spiracle is formed at the end of valve pocket near magnetic washer side, and forming an annular space between valve pocket end outer wall and magnetic washer inwall, spool is communicated with the annular space outside valve pocket by spiracle with the gap between valve pocket, magnetic sheath near the end of armature.
Further, described spiracle is the elongated hole vertically extended.
Wherein, described valve pocket has a pollutant exhaust hole near the side of magnetic washer, and this pollutant exhaust hole is between the voltage supply mouth and magnetic washer of valve pocket, and the gap between valve pocket with spool is communicated with pressure relief opening by described pollutant exhaust hole.Further, the elongated hole on described pollutant exhaust hole is positioned at below spool valve pocket and for vertically extending.
In said structure, described valve pocket is arranged in a solenoid valve supporting tool, and the described solenoid valve supporting tool part be positioned at below valve pocket has the fluting for fluid turnover, and this fluting and annular space and spiracle form a runner.Further, described fluting vertically extends.
The utility model increases by an elongated spiracle being positioned at the valve pocket above spool, simultaneously offer fluting for fluid turnover being positioned at the solenoid valve supporting tool part below valve pocket, when electromagnetic valve work, contaminated oil can only arrive the spiracle on valve pocket top from valve pocket bottom through the elongated runner of half-turn and enter in the electromagnet portion of solenoid valve by spiracle, make contaminant particle automatically can concentrate on lower half portion of runner due to space and Action of Gravity Field like this, decrease the contaminant particle finally entering spiracle few, improve contamination resistance, and structure is simple, processing realizes easily, substantially extra cost can not be increased.

Fig. 1 is the structural representation of existing solenoid valve;
Fig. 2 is the structural representation of the utility model solenoid valve;
Wherein description of reference numerals is as follows:
1 is armature; 2 is spool; 3 is valve pocket; 4 is spiracle; 5 is coil block; 6 is magnetic sheath; 7 is plug shell; 8 is magnetic cover; 9 is magnetic washer; 10 is pollutant exhaust hole; 11 is capping.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
The solenoid valve with long oil road spiracle that the utility model provides, as shown in Figure 2, comprises electromagnet portion (part in figure in dotted line), spool 2, valve pocket 3, plug shell 7, and wherein spool 2 is positioned at valve pocket 3 inside and can moves axially.As shown in Figure 2, electromagnet portion comprises:
Magnetic washer 9, is nested in outside an axially end of valve pocket 3;
Magnetic cover 8, its axis one end near valve pocket 3 is nested in outside magnetic washer 9;
Coil block 5, is made up of coil brace and winding coil, and it is positioned at magnetic cover 8;
Magnetic sheath 6, is configured in coil block 5;
Armature 1, to be arranged in magnetic sheath 6 and to move vertically under the electromagnetic force produced at winding coil.
In the present embodiment, plug shell 7 is independently working of plastics, and it is connected with the coil brace of coil block 5, and is positioned at the end of magnetic cover 9 away from valve pocket 3.
The valve pocket 3 be positioned at above spool 2 has a spiracle 11, described spiracle 11 is formed at the end of valve pocket 3 near magnetic washer 9 side, and forming an annular space between valve pocket end outer wall and magnetic washer 9 inwall, spool 2 is communicated with the annular space outside valve pocket 3 by spiracle 4 with the gap between valve pocket 3, magnetic sheath 6 near the end of armature 1.In the present embodiment, spiracle 11 is the elongated hole vertically extended.
Simultaneously, valve pocket 3 is arranged in a solenoid valve supporting tool (not shown), the described solenoid valve supporting tool part be positioned at below valve pocket 3 has the fluting (not shown) for fluid turnover, and this fluting forms a runner with spiracle 4 and the annular space between valve pocket 3 and magnetic washer 9.Preferably, described fluting vertically extends, and is two half-turn runners between fluting and spiracle 4.
