所述控制活塞的另一端与节流孔板间设有很小的间隙。
所述壳体内设有进流通道、回流通道、回流节流孔、进流节流孔，进流通道与进流节流孔连通，回流节流孔与回流通道连通，回流孔与回流节流孔连通，高压液体通过进流通道和进流节流孔进入由控制活塞、回流通道，壳体和节流孔板共同形成的控制室内。
本发明与已有技术相比具有以下优点：
本发明结构简单、紧凑，合理；能保证阀座与节流孔板贴合后的密封性，降低了对阀座加工要求，可提高喷射阀的密封性。
附图说明
图1为本发明结构示意图。
图2为本发明电控喷油器结构示意图。
具体实施方式
下面本发明将结合附图中的实施例作进一步描述：
如图1～图2所示：包括电磁铁1、电磁铁紧帽2、电磁铁弹簧3、衔铁4、衬环5、导向座6、压紧螺母7、定位板8、阀座9、节流孔板10、调压弹簧11、顶杆12、油嘴偶件13、紧帽14、壳体15、钢球16、回流节流孔17、回流孔18、进流节流孔19、控制室20、进流通道21、控制活塞22、回流通道23。
本发明采用阀座9安装在节流孔板10上，所述壳体15内设有控制活塞22，控制活塞22与壳体15配合，在不漏油的前提下保持运动的灵活性，控制活塞22上装有调压弹簧11，控制活塞22的一端上连接顶杆12，且通过顶杆12与油嘴偶件13连接，由紧帽14将油嘴偶件13固定在壳体15上，控制活塞22的另一端与节流孔板10间设有很小的间隙，压紧螺母7通过定位板8将节流孔板10压紧在壳体15上，使壳体15与节流孔板10贴合连接，定位板8将导向座6定位在壳体15上合适位置；衔铁4安装在导向座6内，衔铁4可以在导向座6内往复运动，衔铁4往复运动的距离由衔铁4与电磁铁1之间的衬环5的厚度来调节，电磁铁紧帽2将电磁铁1、衬环5和导向座6压紧并固定在壳体15上；在壳体15内设有进流通道21、回流通道23，进流通道21与进流节流孔19连通，高压液体通过进流通道21和进流节流孔19进入由控制活塞22、回流通道23，壳体15和节流孔板10共同形成的控制室20内，钢球16的一部分压入衔铁4的预留孔内，钢球16与衔铁4过盈配合，电磁铁弹簧3设置在衔铁4上，阀座9的凹球面与钢球16突出衔铁4的部分向接触，使电磁铁弹簧3上的预紧力始终垂直作用在阀座9与节流孔板10贴合面上，阀座9的密封面大于回流节流孔周围的密封面，保证了阀座9与节流孔板10贴合后的密封性，降低了对阀座9加工要求。
当电磁铁1没有通电时，电磁铁弹簧3上的预紧力作用在衔铁4上，并通过钢球16使阀座9与节流孔板10贴合，切断了控制室20内液体通过设置在节流孔板10的回流节流孔17回到回流通道23中；控制室20内的高压液体压力作用在控制活塞22的端面上，高压液体压力通过进流通道21作用在油嘴偶件13上，作用在油嘴偶件13上的力小于作用在控制活塞22的力，油嘴偶件13保持关闭。
当电磁铁1通电时，电磁力克服电磁铁弹簧3预紧力，将衔铁4吸合，作用在阀座9上的预紧力消失，在液体压力作用下阀座9开启，回流节流孔17与回流通道23连通，回流孔18与回流节流孔17连通，控制室20内的液体通过回流孔18到回流节流孔17进入回流通道23，流入控制室20的液体小于流出的液体，控制室20内液体压力减小，此时作用在油嘴偶件13的力大于控制室20内液体作用控制活塞22上的力，油嘴偶件13在液体压力作用下开启，这样根据设定可以重复的开启和关闭。
