Abstract

A invenção diz respeito a um dispositivo de transmissão de força (13) para um comando variável de válvula (10) de um motor de combustão interna. O dispositivo de transmissão de força (13) possui um primeiro dispositivo de alavanca (14). O primeiro dispositivo de alavanca (14) possui um primeiro seguidor de came (24) e um primeiro receptáculo (30) para o primeiro seguidor de came (24). O primeiro seguidor de came (24) é deslocável e bloqueável no primeiro receptáculo (30). O dispositivo de transmissão de força (13) possui um segundo dispositivo de alavanca (16). O segundo dispositivo de alavanca (16) possui um segundo seguidor de came (54) e um segundo receptáculo (58) para o segundo seguidor de came (54). O segundo seguidor de came (54) é deslocável e bloqueável no segundo receptáculo (58).
