Abstract

"COMPRESSOR HERMéTICO". A invenção refere-se a um compressor hermético usado em um ciclo de refrigeração como um refrigerador, e revela um compressor de baixo ruído projetado para atenuar um som ressonante em uma câmara de compressão e pulso de pressão de entrada mais operacionalmente em uma posição adjacente a suas fontes, cujo pulso de pressão de entrada ocorre em uma porta de válvula de entrada. No compressor, um espaço de ressonância 38 é provido adjacente à porta de válvula de entrada 29 que fica mais próximo, em distância, a uma fonte de ruído. Como resultado, ruído pode ser reduzido mais operacionalmente do que as funções de silenciamento de um silenciador de entrada 31 podem fazer. Em adição, embora características acústicas do silenciador de entrada 31 amplifiquem ruídos tendo freq³ências específicas, tais ruídos podem ser atenuados antes de serem amplificados.
