Claims (4)
- n+x 로브의 한쌍의 나란한 암로브 환상부(14)를 관통하여 연장되며 이에 맞물린 n개 로브를 갖는 단일의 숫로브 회전자(16)를 포함하며, 각 환상부가 외부기어를 갖는 분리된 편심바퀴(12) 내에서 저어널 연결되고 펌프의 동체내에서 저어널 연결되며, 기어들을 반대방향으로 회전시키기 위한 랙과 피니언을 포함하여 최대 펌프 출력을 위한 정렬된 동일한 위치와 최소 펌프 출력을 위한 정렬되지 않은 거울상 위치들 사이의 환상부를 형성하도록 하고, 이와 같은 최대와 최소 출력사이의 이동이 펌프의 고정된 유입구와 유출구 포트와 관련하는 가변출력 오일펌프에 있어서, 반대방향으로 상기 기어들을 구동시키기 위해 펌프출력으로부터 직접 또는 간접으로 획득된 압력을 사용하는 수압 시스템을 포함함을 특징으로 하는 가변 출력 오일펌프.
- 제1항에 있어서, 상기 기어들이 실린더내 피스톤에 의해 구동되며, 압력 유체가 조정 보어내에 놓여지며 통로에 의해 실린더에 연결된 스푸울 밸브에 의해 상기 피스톤의 맞은편측으로 향하도록 됨을 특징으로 하는 가변출력 오일펌프.
- 제2항에 있어서, 획득된 펌프출력에 의해 한 방향으로 그리고 피스톤 이동으로부터 획득된 압력에 의해 그 반대방향으로 이동시키도록 작용받도록 스푸울 밸브(60)가 배치됨을 특징으로 하는 가변출력 오일펌프.
- 제3항에 있어서, 스푸울 밸브(60)가 압축 스프링(90)을 위한 접합점을 형성하는 레버 시스템에 기계적으로 연결되며, 피스톤이 전술한 스프링의 맞은편 단부 접합점을 형성시킴을 특징으로 하는 가변출력 오일펌프.
