Innenzahnradmaschine, insbesondere Innenzahnradpumpe

摘要

The pump has a two-part filler section (31) and a sealing roller (36), pressed against the inclined face of one part by a spring (37). The spring is bent like a hairpin, and its legs engage approximately axis-parallel on the sealing roller respective to a support surface (38). The curved end (39) of the spring projects into a free space (40) of the casing (4), respectively of an axial plate engaging on the filler section. The filler section is symmetrically shaped, with spring-loaded sealing rollers in symmetrically positioned joint face areas (32). The springs have associated free areas.
