Abstract

"DISPOSITIVO DE FUNCIONAMENTO DE VáLVULA EM MOTOR DE COMBUSTãO INTERNA". Em um dispositivo de funcionamento de válvula em um motor de combustão interna, incluíndo dois eixos de braços de balancim (32, 33) montados em uma cabeça de cilindro (3) e cames de admissão e de exaustão (21, 22) e válvulas de admissão e de exaustão (13, 14), que são conectados uns aos outros por meio de braços de balancim oscilavelmente conduzidos nos eixos de braços de balancim, uma placa detentora (42) é fixada de maneira apertada à cabeça de cilindro (3) entre os dois eixos de braços de balancim (32, 33) por um parafuso de aperto (43). Porções de encaixe (42c, 42d) formados em lados anteriores de primeiro e segundo braços (42a, 42b) da placa detentora (42) em uma direção (a) de rotação de aperto do parafuso de aperto são, respectivamente, trazidas em encaixe com porções encaixadas (32a, 33a) formadas nos dois eixos de braços de balancim (32, 33). Desse modo, é possível obter, com segurança, a prevenção da rotação dos dois eixos de braços de balancim.
