Abstract

"DISPOSITIVO DE MUDANçA DE RAZãO DE COMPRESSãO EM MOTOR DE COMBUSTãO INTERNA". Dispositivo de mudança de razão de compressão em um motor de combustão interna, inclui um elemento interno de pistão (5A), um elemento externo de pistão (5b) encaixado deslizavelmente através de uma periferia externa do elemento interno de pistão (5a) para movimento deslizante apenas em uma direção axial e capaz de ser movido entre uma posição de razão de compressão inferior (L) e uma posição de razão de compressão superior (H), um elemento de avultamento (14) capaz de ser girado em torno de eixos dos elementos interno e externo de pistão (5a, 5b) entre uma posição de não-avultamento (A) e uma posição de avultamento (B) e um atuador (20) conectado ao elemento de avultamento 14) para girar o referido elemento de avultamento (14) para a posição de não-avultamento (A) e a posição de avultamento (B). O elemento de avultamento (14) permite o movimento do elemento externo de pistão (5b) para a posição de razão de compressão inferior (L), quando está na posição de não-avultamento (A) e retém o elemento externo de pistão (5b) na posição de razão de compressão superior (5b) na posição de razão de compressão superior (H), quando tiver sido girado para a posição de avultamento (B). Desse modo, o elemento externo de pistão pode ser operado simples e precisamente para a posição de razão de compressão inferior e para a posição de razão de compressão superior, sem ser girado.
