Abstract

resumo patente de invenção: "cabeçote de cilindro de motor de combustão interna". a presente invenção refere-se ao cabeçote de cilindro (1) que inclui uma camisa d'água (4) formada em torno de um furo de montagem de vela de ignição (5). as superfícies superiores (de 12 a 14) de porções da camisa d'água (4) entre os orifícios de admissão (7) e o furo de montagem de vela de ignição (5) e entre os orifícios de escape (8) e o furo de montagem de vela de ignição são ajustadas para ficarem mais baixas do que as superfícies superiores (de 15 a 17) das porções remanescentes da camisa d'água (4) em torno do furo de montagem de vela de ignição (5) para aumentar a rigidez. assim, a deformação do cabeçote (1) devido à pressão interna do cilindro é limitada, e a concentração de esforço em torno do furo de montagem de vela de ignição (5) devido a tal deformação é reduzida.
