본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 연료 분사펌프의 서어보밸브식 타이머의 한 실시예를 나타낸 단면도,
제2도는 다른 실시예를 나타낸 단면도.

Claims (6)

  1. 고압실과 저압실 사이의 압력의 차에 기초하여 연료분사시기를 제어하는 서어보 밸브식 타이머에 있어서, 고압실과 저압실 사이에 이동할 수 있도록 설치되어, 고압실 및/또는 저압실로 도입되는 연료 압력에 따라서 동작하는 연료 분사시기 조정용의 타이며 피스톤과, 타이머 피스톤의 동작을 제어하는 서어보 밸브와, 저압실의 연료 압력을 조정하는 압력 제어수단 등을 설치한 것을 특징으로 하는 연료 분사펌프의 서어보밸브식 타이머.
  2. 제1항에 있어서, 압력 제어수단은 전자 밸브를 구비하였고, 이 전자밸브는 적어도 저압실로 연결되어 있으며, 전자밸브와 저압실 사이의 연료의 흐름을 연통함에 따라 저압실의 연료 압력을 제어한 것을 특징으로 하는 연료 분사펌프의 서어보 밸브식 타이머.
  3. 제2항에 있어서, 전자밸브는 2개의 연료포오트를 구비하여, 한편은 저압실로, 다른편은 펌프실로 연결한 것을 특징으로 하는 연료 분사펌프의 서어보 밸브식 타이머.
  4. 제3항에 있어서, 저압실은 오리피스를 가진 저압포오트를 구비한 것을 특징으로 하는 연료 분사펌프의 서어보 밸브식 타이머.
  5. 제4항에 있어서, 서어보밸브는 고압실에서 펌프실로 흐르는 연료를 차단하는 책밸브를 구비한 것을 특징으로 하는 연료 분사펌프의 서어보 밸브식 타이머.
  6. 제2항에 있어서, 전자밸브는 2개의 연료포오트를 구비하여, 한편은 저압실로, 다른편은 저압포오트로 연결한 것을 특징으로 하는 연료 분사펌프의 서어보 밸브식 타이머.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
