<p>The internal gear pump is partic. intended for a motor vehicle engine. It takes in oil from a supply line (6) into a suction chamber, moves it into a pressure chamber (8) and from there, via a pressure line (12) to engine lubrication points. A further pressure line (12) is arranged in the region of the addendum circle of the pinion (3) pas the chamber (8) as seen in the direction of rotation (7) and before the area (10) where to dedendum circle of the gear ring (2) is nearest to the addendum circle of the pinion. The pressure line (12) may connect into a pressure chamber (11) adjacent to the inside of the pinion addendum circle.</p> |
