Abstract

Un motor endotérmico, que comprende: una pluralidad de cámaras de combustión, cada una de las cuales está dispuesta con, al menos, una válvula y una palanca (11) adaptada para provocar la apertura de dicha válvula; un árbol de levas (1) con una pluralidad de levas adaptadas para controlar dichas palancas; un cabezal de cilindro que tiene un eje de soporte (2) sobre el cual una pluralidad de bujes (16, 16') está montada en forma giratoria y excéntrica, cada uno de los cuales sostiene de manera giratoria una de dichas palancas; un accionador (8) adaptado para hacer girar dichos bujes en un ángulo predeterminado; caracterizado porque dichos bujes se integran recíprocamente uno en otro, girando alrededor de dicho eje de soporte por medio de una placa (12), preferiblemente formada por una serie de placas superpuestas (14), conectada en forma rígida a ellos, al menos en la dirección de rotación.
