An oil-less compressor, having polymeric seals and a crank mechanism which is vulnerable to dust arising from such seals, is provided with a dust-exclusion barrier that protects the crank mechanism from being exposed to such dust. The first stage of the compressor preferably draws its intake from the crankcase, providing a pressure differential and gas flow that sweeps seal dust away from the crank mechanism.
La présente invention concerne un compresseur autolubrifiant ayant des joints polymères ainsi qu~une commande à manivelle vulnérable à la poussière provenant de tels joints, munie d~une barrière d~exclusion de la poussière protégeant la commande à manivelle de ladite poussière. Le premier étage du compresseur aspire de préférence son admission depuis le carter, fournissant un différentiel de pression et un écoulement de gaz qui repousse la poussière de joint de la commande à manivelle.
