Abstract

Patente de Invenção: <B>"CABEçA DE CILINDRO DE MOTOR TIPO DOHC"<D>. Para fixar um suporte de came por método não-paralelo em relação à superfície da gaxeta da cabeça, sem causar interferência com o orifício de vela. Forma-se um orifício de vela (44), de modo que seu eixo fique em ângulos retos em comparação com a superfície correspondente (41) da lateral do cilindro em relação à cabeça do referido cilindro. A superfície correspondente (46) da lateral do suporte para a cabeça de cilindro (3) do suporte de came (45) fica inclinada de forma não-paralela em relação à superfície correspondente (41) da lateral do cilindro, a direção axial do parafuso tensor (48) do suporte de came que fixa o suporte de came (45) na cabeça de cilindro (3) fica em paralelo em relação ao suporte de vela (44) e não paralelamente à superfície correspondente (46) do suporte, mas em paralelo com o eixo geométrico C da vela de ignição 43.
