본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제4도는 제1도에 도시된 케이싱의 결합면을 나타낸 도면. 제5도는 제1도에 도시된 커버의 결합면을 나타낸 도면. 제 7도는 제1도에 도시된 내접치차펌프의 오일포켓의 작용을 설명하는 부분 도면도.

Claims (4)

  1. 케이싱과 이 케이싱상에 장착된 커버와, 조립된 케이싱과 커버간에 형성된 펌프실과, 이 펌프실내에 접동자유롭게 설치된 내치치차와, 상기 펌프실내에 회전자유롭게 설치되고 외부로부터 회전구동되어 상기 내치치차와 맞물리고 이것을 구동하여 펌프작용을 행하는 외치치차와, 상기 내치치차의 접동작용을 규제하는 고정필러와, 상기 커버에 형성된 흡입구에 대향하는 키이싱의 접동면에 설치된 적어도 하나의 제1오일포켓과, 상기 케이싱의 토출구에 대향하여 커버에 설치된 제1오일포켓과, 펌프실내의 측별과 고정필러와의 사이에서 내치치차가 접동하는 케이싱과 커버의 접동면에 적어도 하나의 제2오일 포켓으로 이루어진 것을 특징하는 내접치차 펌프
  2. 제1항에 있어서, 상기 제2오일포켓이 압력오일을 공급하는 도입통로를 구비한 것을 특징으로 하는 내접치차펌프
  3. 제1항 또는 제2항에 있어서, 적어도 하나의 제3오일포켓이 상기 커버의 접동면의 일부와 상기 케이싱의 접동면의 일부중 적어도 하나에 제공되고, 상기 외치치차가 개개의 케이싱과 커버의 접동면에서 접동하는 것을 특징으로 하는 내접치차 펌프
  4. 제3항에 있어서, 상기 제3오일포켓이 압력오일을 공급하는 도입통로를 구비한 것을 특징으로 하는 내접치차 펌프
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
