PUMPE, INSBESONDERE FLUEGELZELLENPUMPE, MIT EINER GLEITLAGERUNG

摘要

A mode of assembly for a vane pump rotor and drive shaft provides a construction wherein a plain, i.e., sleeve or collar type bearing can be used for the support of the drive shaft. The arrangement affords axial positional securing, i.e., axial fixation of the drive shaft with a spring ring peripherally confined by a recess in the pump rotor to prevent its being dislodged and thus affording safety in maintaining axial securement of the drive shaft.
