크랭크 샤프트(6)가 외부의 동력원으로부터 동력을 전달받아 회전하게 되면 크랭크 롤러(2A,2B)와 본체의 내면과 일정한 거리를 유지한 공간에 환형 압축판(1)에 접하며 회전하게 된다.When the crankshaft 6 is rotated by receiving power from an external power source, the crank shaft 6 rotates while contacting the annular compression plate 1 in a space maintained at a constant distance from the inner surfaces of the crank rollers 2A and 2B.

도 7을 참조하면 펌프의 회전각 0도 일 때 펌프 본체(3)와 환형 압축판(1) 사이에 AA공간이 형성되며 크랭크 샤프트(6)가 점차 회전하게 되면 펌프 본체(3)와 크랭크 롤러(2A,2B)에 접한 환형 압축판(1)은 탄성 변형이 되기 시작한다. Referring to FIG. 7, an AA space is formed between the pump body 3 and the annular compression plate 1 when the rotation angle of the pump is 0 degrees, and when the crank shaft 6 gradually rotates, the pump body 3 and the crank rollers. The annular compression plate 1 in contact with 2A and 2B starts to elastically deform.
