Gearwheel pump with variable flow volumes has displacement arrangement in tooth gaps with variable displacement volumes connected to control chamber in base body

摘要

The gearwheel pump has a gear wheel that rotates about a rotation axis with a base body and a number of teeth, between which gaps are provided as transport volumes and a displacement arrangement in the tooth gaps with variable displacement volumes connected to a control chamber in the base body. An independent claim is also included for a membrane for gearwheel pumps.
