Abstract
Description
Claims (1)
- 밸브, 바람직하게는 비교적 대형 디젤 엔진용의 비교적 대형의 연료 분사 밸브(1)를 그 밸브(1)의 입구측에 압축 오일을 공급함으로써 테스트하며, 입구측에서의 오일 압력을 점진적으로 상승시키면서 기록하는 것인 테스트 방법에 있어서,밸브(1)의 개방 압력을 초과하고, 그에 따라 입구측의 압력이 강하하는 순간에 압력 상승을 일시적으로 전자적으로 중단하며, 그 순간에 입구측에 오일 압력을 제공하는 압축 공기 공급을 전자적으로 일시적으로 중단하고, 그 후에 개방 압력을 현재 상태의 분사 밸브가 엔진에 사용하기에 적합한 가를 결정하는 데에 사용하는 것을 특징으로 하는 방법.
