Abstract
"SISTEMA DE CICLO DE REFRIGERAçãO". Um ciclo de refrigeração tem um compressor rotativo de dois cilindros. Um mecanismo de compressão do compressor tem um mecanismo de comutação para comutar a pressão no lado de trás de uma pá para alta ou baixa, e, quando comutado para baixa pressão, o mecanismo de compressão aumenta a pressão no interior da câmara do cilindro. Quando uma carga é grande, o lado de trás de uma pá de um mecanismo de compressão é comutado para uma alta pressão para realizar operação normal e, quando a carga é pequena, o lado de trás da pá de um mecanismo de compressão é comutado para baixa pressão, e a pressão no interior da câmara do cilindro é aumentada, separando a pá de um rolo para realizar operação de não compressão. A estrutura apresentada não produz ruído e não provoca danos na pá, e permite que o dispositivo do ciclo de refrigeração continue a operação sem compressão.
