A lock cylinder with a cylinder core rotably mounted in a housing and normally locked against rotation by means of pin tumblers comprising core and housing pins mounted in core and housing orifices, spring-loaded against the housing and displaceable into a release position by insertion of a key (2) into a lock channel, wherein the cylidner core has at least one support pin inserted in a radial orifice of the cylinder core and spatially associated with a pin tumbler in such a way that the pin tumbler can be located between the support pin and core pin by interposition of a spacer (9) movably associated with the key (2), wherein the radial bore bearing the support pin extends obliquely to the orifice bearing the core pin, and the direction of movement of the spacer (9) extends obliquely to the broadside face of the key (2).

L'invention concerne un barillet de serrure à bloc cylindrique central monté rotatif dans un boîtier, et normalement bloqué en rotation par le biais de gorges à levier comprenant des broches de bloc central et de boîtier placées dans différents orifices du bloc central et du boîtier. Le bloc central, contraint par ressort contre le boîtier, peut être déplacé en position libérable par l'insertion d'une clé (2) dans un canal du barillet. Ledit bloc central comporte au moins une broche support, insérée dans un orifice radial et en relation spatiale avec une gorge à levier, de sorte que la gorge à levier puisse prendre place entre la broche support et une broche de bloc central grâce à l'implantation d'un élément d'espacement intercalaire (9) en relation mobile avec la clé. Le trou radial dans lequel est insérée la broche support s'étend de manière oblique vers l'orifice portant la broche de bloc central, et la direction du mouvement de cet élément d'espacement (9) est oblique par rapport à la face large de la clé (2).
