<p>The vane cell oil pump has a fixed housing (1). It has a rotating group including a shaft (5) and a side plate (19) inside the housing. There are seals (9) to prevent fluid leaking along the shaft. - Sealing lips (16) touch the shaft and an axial sealing lip (31) presses against the flat face of the side plate to prevent radial leakage. There may be a permanent or temporary axial gap (27) between the side plate and the housing. A spacer ring (29) may fit in a circular groove in the flat face of the housing.</p> |
