Ihinduramiterere rya compressor yuburyo bwubwoko bwa piston ni uko piston izunguruka nayo bita rotor izunguruka ihuye na kontour ya silinderi kandi icyuma gihamye gikanda firigo.Ugereranije na compressor zisubiranamo, compressor izunguruka iroroshye kandi yoroshye mubwubatsi kandi igizwe nibice bike.Mubyongeyeho, compressor ya rotary iruta coefficente yimikorere no gukora neza.Ariko, ubunyangamugayo na antiabrasion birakenewe mugutunganya ibice bihuza.Kugeza ubu, ubwoko bwa piston buzunguruka bukoreshwa cyane.
