| 摘要 |
The present invention relates to a double internal gear pump (1) including two internal gear pumps (2) as the reverse transmission pump of a hydraulic slip control double circuit-vehicle brake system. The ring gears (3) of an internal gear pump (2) include an external toothed part to be engaged with them. One internal gear pump (2) is operated by the other internal gear pump (2) through the external toothed part. The present invention allows the ring gears (3) to be supported in a plane on which an internal toothed part (15) is arranged next to the external toothed part (5) to be slid in an axial direction. |
