Abstract

"MOTOR COM TAXA DE COMPRESSãO VARIáVEL". A presente invenção refere-se a um motor com taxa de compressão variável que inclui um eixo de suporte posicionado excentricamente com relação a eixos rotativos. Uma saliência redutora (88) é provida em um local na direção circunferencial dos eixos rotativos de modo a se projetar para fora na direção radial. Um membro oscilador (93) tem um par de porções de engate (93a, 93b) com fases respectivas deslocadas uma da outra e que engatam a saliência redutora (88). O membro oscilador (93) é polarizado por mola em uma direção na qual uma das duas porções de engate (93a, 93b) engata a saliência redutora e é montado sobre o membro de eixo (92) de modo a ser capaz de oscilar em torno do eixo geométrico do membro de eixo (92). Um atuador (97) é acionado por meio da pressão negativa de motor e é conectado ao membro oscilador (93) de modo a oscilar o membro oscilador em uma direção oposta à direção de polarização de mola.
