Abstract
Patente de Invenção: <B> "SISTEMA DE CENTRALIZAçãO PARA MáQUINA DE PISTãO LIVRE" <D> Um aparelho de centralização para um motor Stirling de pistão livre incluindo uma válvula reguladora de pressão (50) que conecta uma passagem entre o espaço de trabalho e o espaço posterior quando ambos a) a pressão média no espaço posterior excede a pressão média no espaço de trabalho como resultado do pistão (14) desviar uma mola (32, 34) e simultaneamente (b) a pressão instantânea no espaço posterior exceder a pressão instantânea no espaço de trabalho. Um diafragma (56) espalha através de uma cavidade do alojamento do atuador, dividindo a cavidade em uma câmara superior e uma câmara posterior. Uma válvula conectora (52) é conectada ao diafragma para abrir e fechar a válvula mediante o deslocamento do diafragma. Quando a pressão média do espaço posterior excede a pressão média do espaço de trabalho, o diafragma (56) é deslocado para abrir a válvula, conectando o espaço de trabalho e o espaço posterior em comunicação por fluido. Uma válvula verificadora (88) permite o fluxo de gás em apenas uma direção: do espaço posterior (20) para o espaço de trabalho (18). Uma disposição similar pode ser incluída para causar também o fluxo do espaço de trabalho para o espaço posterior (20) quando a pressão média do espaço de trabalho exceder a pressão média do espaço posterior, de forma a centralizar o pistão (14) contra vazamentos em qualquer direção.
