Abstract

Un cylindre pour serrure comprend un barillet qui présente une rangée d'ouvertures pour goupilles le long de son axe, et un logement de barillet qui comporte une rangée d'ouvertures pour goupilles alignées avec celles du barillet. Les goupilles placées dans les ouvertures pour goupilles présentent des canaux continus sur la surface de leur circonférence. Dans chacune des ouvertures de la première rangée, il y a une bille antifrottement sous la goupille qui s'y trouve. Ces billes entrent en contact avec la clef quand on l'introduit dans le barillet. Ce genre de cylindre pour serrure est susceptible d'offrir une protection efficace contre le vol.
