Description
Claims (4)
- 좌측 뱅크와 우측뱅크의 밸브를 개폐작동하기 위한 좌·우캠축 스프라켓과 크랭크축 스프라켓을 연결하는 타이밍 체인을 포함하여 구성되는 V형 엔진의 캠축 구동장치에 있어서,상기 캠축 스프라켓이 끼워져 장착되는 캠축 부위에 형성되는 유압실과;상기 유압실에 대항되는 캠축 스프라켓의 내경면에 형성되는 고정홈과;상기 고정홈에 일단이 끼워지고 타단은 상기 유압실로 연장된 핀과;상기 유압실 내의 핀의 단부에 일체로 형성되어 유압실 내벽면의 안내를 따라 이동가능하게 수용된 피스톤과;상기 핀이 고정홈으로부터 빠지는 방향으로 피스톤을 이동시키도록 유압실에 연통하도록 형성되어 오일펌프로부터 급송되는 오일을 공급안내하는 오일공급통로와 ;엔진의 저속, 저부하 운전시 상기 오일공급통로를 개방하고 고속,고부하 운전시에는 차단하도록 작동하며 또 차단 작동시 상기 오일공급통로를 대기에 개방하는 솔레노이드 밸브;로 구성하여상기 일측 뱅크의 캠축 스프라켓은 엔진의 저속, 저부하 운전시 캠축에의 고정상태가 해체되어 아이들 회전하게 되므로써 캠축의 회전구동이 정지되는 것을 특징으로 하는 V형 엔진의 선택적 캠축 구동장치
- 삭제
- 제 1 항에 있어서,상기 피스톤은 오일압 작용 방향에 대하여 탄발하는 스프링에 의해 지지되며 이 스프링의 탄성력은 오일압보다 작은 것을 특징으로 하는 V형 엔진의 선택적 캠축 구동장치
- 제 1 항에 있어서,상기 솔레노이드 밸브는 전자제어 장치에 의해 작동이 제어되는 3방밸브인것을 특징으로 하는 V형 엔진의 선택적 캠축 구동장치
