Abstract
dispositivo de atuação comutável para uma válvula de elevação de um motor de combustão interna, motor de combustão interna e veículo motorizado. a presente invenção se refere a um dispositivo de atuação comutável (100) para uma válvula de troca de carga. o dispositivo de atuação comutável (100) compreende um balanceiro de duas partes (10). este tem uma primeira parte do balanceiro (1a) articulado em torno de um eixo do balanceiro (2), na qual uma luva de rolamento (1a1) é fixada concentricamente ao eixo do balanceiro (2) assim como uma segunda parte do balanceiro (1b) montada na luva do rolamento (1a1) de forma articulada. além disso, tanto a primeira quanto a segunda parte do balanceiro (1a, 1b) têm, cada uma, um recesso (3a, 3b), em que um elemento de travamento (4a) de um dispositivo de acoplamento (4) do dispositivo de atuação comutável (100) pode facultativamente engatar ou não com ambos os recessos (3a, 3b). com isso, uma atuação da válvula de elevação, preferencialmente uma mudança entre uma posição fechada e uma posição aberta da válvula de elevação, é interrompida se o elemento de travamento (4a) não estiver em engate com ambos os recessos (3a, 3b). a invenção também se refere a um motor de combustão interna (20) e um veículo motorizado (30).
