Zusammenfassung: | The pump comprises a housing with a rotor, and grooves for spring-loaded check vanes (30). An even number of regulator faces (22) are distributed over the circumferential surface (20) of the rotor (16). The faces are identical, and are positioned opposite to each other in pairs. There are more regulator faces than check vanes. The rotor has six regulator faces and four check vanes, which are relatively offset through 90 degrees . The regulator faces are offset through 60 degrees , and all have an identical contour. The chambers (48) formed between rotor surface and housing, have the same volume. |
