Abstract
"APERFEIçOAMENTOS EM DISPOSITIVOS PARA CONTATO DE CAME". A invenção refere-se a dispositivos de contato de came aperfeiçoados para uso em motores de combustão interna e, de preferência, para uso em motores de combustão interna tendo regulagem de válvula variável. Em particular, o uso de cerâmica, incluindo nitreto de silício e carboneto de silício tem sido demonstrado como proporcionando superfícies de contato de came efetivas, permitindo que um eixo de came axialmente deslocável tendo um came de perfis variáveis a ser posto em funcionamento com aperfeiçoamentos resultantes na velocidade em marcha lenta e na eficiência volumétrica.
