Dans le compresseur, un gaz comprimé est déchargé plusieurs fois pendant qu'un moteur d'entraînement (20) pivote d'un tour entraînant la rotation des deux engrenages (40, 50) qui s'engrène l'un avec l'autre; ainsi, l'abrasion des deux engrenages (40, 50) et des composants qui exécutent un mouvement relatif avec les engrenages est réduit.
