Abstract

"CABEçOTE DE CILINDRO PARA MOTOR DE COMBUSTãO INTERNA" Um cabeçote de cilindro para um motor de combustão de tipo diesel tem um conduto de entrada (10 do assim chamado tipo tangencial cuja boca levando para dentro da câmara de combustão (3) é controlado por uma válvula tipo cogumelo convencional (14). A válvula coopera com um assento de válvula(11) formada em um anel de assento de válvula (12) que está disposta em um recesso fresado (13) que circunda a boca do conduto de entrada (10). Em uma superfície de ressalto (19) formada pelo recesso fresado (13) o anel de assento de válvula (12) conecta-se ao conduto de entrada (10) em um diâmetro maior que aquele exibido pelo conduto de entrada da superfície de ressalto. O anel de assento de válvula (12) possui adicionalmente, em seu lado voltado radialmente para dentro, um formato arqueado (20) em pelo menos parte do anel de assento de válvula (12) que define a área de fluxo direto do último. Isto torna possível para o ar de entrada que leva ao conduto de entrada não ser submetido a alterações substanciais de fluxo mesmo se existe uma certa falta de concentricidade na conexão entre o conduto de entrada (10) e o anel de assento de válvula (12).
