- 貫通開口(24)が段部(51)を有しており、該段部から下流に向かって、直径の拡大された下側の区分(49)が延びており、該区分内に案内部材(35)、渦流部材(47)及び弁座部材(26)が収容されている請求項4記載の燃料噴射弁。
- 案内部材(35)の上側の端面(59)が部分的に弁座支持体(21)の段部(51)に接触している請求項5記載の燃料噴射弁。
- 弁座部材(26)が環状の溶接継ぎ目(61)によって弁座支持体(21)に結合されている請求項4から6のいずれか1項記載の燃料噴射弁。
- 弁座部材(26)がフランジ(64)を有しており、該フランジが弁座支持体(21)に溶接継ぎ目(61)によって結合されている請求項7記載の燃料噴射弁。
- 弁座部材(26)の下流側に、該弁座部材と溶接若しくはボンディングにより結合された噴射部材(67)を配置してあり、該噴射部材が少なくとも1つの出口開口(32)を有していて、かつ弁座支持体(21)に溶接継ぎ目(61)によって結合されている請求項4記載の燃料噴射弁。
- 弁座部材(26)に取り付け部材(74,74′)を溶接継ぎ目(68)により結合してあり、該取り付け部材が弁座支持体(21)に別の溶接継ぎ目(61)により結合されている請求項4記載の燃料噴射弁。
- 渦流部材(47)及び案内部材(35)のうちの少なくともいずれか一方が外周にセンタリング突出部(100,100′)を有しており、該センタリング突出部が貫通開口(24)内での案内部材(35)、渦流部材(47)及び弁座部材(26)のセンタリングのために役立っている請求項4又は5記載の燃料噴射弁。
