Abstract

''COMPRESSOR HERMéTICO E SISTEMA DE RESFRIAMENTO''. Um compressor hermético da presente invenção é dotado de um ou mais pequenos orifícios 17 formados no invólucro do silenciador de sucção silenciador de sucção com um material de baixa condutividade térmica, como uma resina sintética. Os pequenos orifícios 17 são posicionados em nodos 18 em um modo de vibração para a freq³ência de ressonância do espaço formado no invólucro hermético, de maneira que a amplificação do som de ressonância do espaço no invólucro hermético 1 seja suprimida. Além disto, uma escassez do refrigerante é suplementada pelo gás refrigerante aspirado do invólucro hermético 1 através dos pequenos orifícios quando ocorre devido a uma perda por sucção causada pela resistência da trajetória de fluxo para guiar um gás refrigerante de alta densidade do tubo de sucção para dentro do cilindro 8 de acordo com a circulação do refrigerante.
