Abstract

"DISPOSITIVO PARA A CONVERSãO DE ENERGIA ARMAZENADA EM AR COMPRIMIDO EM TRABALHO MECâNICO". A invenção se refere a um dispositivo para a conversão de energia armazenada em ar comprimido em trabalho mecânico, o qual apresenta os seguintes componentes: ao menos um recipiente de ar comprimido (1) para o armazenamento de ar comprimido; várias unidades de cilindro (5a, 5b, 5c, 5d, 5e, 5f), cada uma com ao menos uma câmara de trabalho pneumática (10, 11) para a descompressão do ar comprimido, e com ao menos uma câmara de trabalho hidráulica (14, 15) para o transporte de um agente hidráulico, sendo que a câmara de trabalho pneumática (10, 11) e a câmara de trabalho hidráulica (14, 15) apresentam, cada, um êmbolo (13), que são acopladas uma com a outra; um conduto de alta pressão hidráulica (22), o qual está em ligação com as câmaras de trabalho hidráulicas (14, 15) das unidades de cilindro (5a, 5b, 5c, 5d, 5e, 5f), e que é configurado para transportar um agente hidráulico que está sob alta pressão; um motor hidráulico, que está em ligação com o conduto de alta pressão hidráulica, e que é acionado pelo agente hidráulico que está sob alta pressão. Um grau de eficiência melhorado é alcançado pelo fato de que está prevista ao menos uma válvula de inversão, a qual liga a câmara de trabalho hidráulica (14, 15) de uma unidade de cilindro, opcionalmente, com o um conduto de alta pressão hidráulica (22) ou com a câmara de trabalho hidráulica (14, 15) de uma outra unidade de cilindro (5a, 5b, 5c, 5d, 5e, 5f).
