<p>The fuel pump, is positioned in a common housing with an electric drive motor. It has a number of individual pump elements (rollers), which are held in grooves in a driven rotor disc and engage on a roller track positioned eccentrically to it. A sealing element (23) is located between the rotor disc (4) and the intermediate plate (10), in the area of the smallest gap between them, and is pressed towards the rotor disc. The sealing element is roller-shaped, and held in a groove (24) of the intermediate plate with a small free play. The groove is widened axially towards the support plate (9) and the base plate (7), forming stops (25a,b)..</p> |
