Abstract

"MáQUINA RECIPROCANTE, COM DUAS SUBCâMARAS". Uma máquina reciprocante inclui um alojamento (12) e meios de pistão (2), que são deslocáveis relativamente ciclicamente ao longo de um eixo (11), para definir uma câmara de trabalho de volume variável (50). Proporciona-se ainda um meio de entrada de ar e um meio de entrada de combustível (100), para admitir ar e combustível na câmara de trabalho, para formar uma mistura inflamável, após compressão de ar nela, e um meio para descarga de produtos de combustão da câmara de trabalho. A câmara de trabalho de volume variável (50) inclui pelo menos duas subcâmaras, uma câmara de combustão (54) e uma câmara principal (52) deslocadas mutuamente no eixo (11), e em comunicação com uma seção transversal (53), na qual o gás na câmara de combustão (54) pode expandir-se, pelo menos parcialmente, lateralmente, na medida em que escoa da câmara de combustão (54) para a câmara principal (52). O meio de admissão de ar, o meio de exaustão e as câmaras (52, 54) são dispostos, de modo que um torvelinho de gás é gerado e mantido em torno do eixo (11) em ambas as câmaras (52, 54), durante operação da máquina. A câmara de combustão (54) é selada e definida lateralmente e em uma extremidade por uma estrutura de parede resistente termicamente e/ou de baixa condutividade térmica integral (40), tendo uma camisa de isolamento térmico circundante (48) e um meio de dissipação térmica associado (47, 49) disposto de modo que, durante operação da máquina, as superfícies (42a, 44) da estrutura de parede ligadas à câmara de combustão são mantidas a uma temperatura, que é substancialmente mais alta do que a das superfícies da parede (31) ligadas à câmara principal (52).
