Double internal gear pump for installation of e.g. hydraulic braking system of vehicle, has pinion meshing with crown and wheel, and drives commonly arranged for internal pumps to drive wheel, where crown and pinion are provided in plane

摘要

The pump (2) has a crown (7) or cogwheel, and a pinion (6) that is placed in the crown, where the pinion meshes with the crown and a drive wheel (18). A set of drives such as drive shafts (20) is commonly arranged for internal gear pumps for driving the drive wheel of the gear pumps. The crown and the pinion are provided in a plane. The set of drives is arranged with a number of teeth that is different from the number of teeth of the drive wheel. A set of shafts (3) of the pumps are provided in a parallel manner, and pumps are separated by a partition (17).
