Internally meshing gear pump - makes use of spring pressure forces to reduce pulsations

摘要

The internal axis gear pump is for hydraulic operating media. It has an externally toothed smaller spur wheel which meshes with an internally toothed larger spur wheel. The gear flanks of the two spur wheels (3,4) standing in counter engagement with each other are capable of being pressed against each other in a play-free, sealing manner by spring pressure forces (27). USE/ADVANTAGE - Gear pump for the automatic drive of a vehicle in which delivery flow pulsations are reduced.
