Abstract

The gear pump with internal teeth has an externally toothed inner rotor, meshing with an eccentric internally toothed outer one. The latter is fixed in the housing, while the drive is taken to the inner rotor. The inner rotor (4) is guided radially in the housing (1) by a recess (13) in one or both ends, into which a boss (12) on the housing or cover (2) protrudes.
