Abstract

Patente de Invenção: <B>"COMPRESSOR DO TIPO COM CAPACIDADE VARIáVEL COM VáLVULA DE SEGURANçA"<D>. Um compressor do tipo com capacidade variável tem uma chapa oscilante, pistões que se alternam nos furos de cilindro, uma câmara de sucção, e uma câmara de descarga. Uma válvula de segurança disposta no compressor. A válvula de segurança tem um membro de assento de válvula com uma passagem de fluxo e um assento de válvula, uma caixa fixada ao membro de assento de válvula, e um elemento de válvula disposto na caixa para cooperação com o assento de válvula. A caixa tem um furo de comunicação formado através da mesma de modo a permitir que o gás flua a partir da passagem de fluxo através do furo de comunicação para o circuito externo. Uma ranhura anular é formada na superfície periférica do elemento de válvula de modo a permitir que um gás vazante flua a partir do espaço de folga entre o elemento de válvula e o alojamento de válvula para o exterior do alojamento de válvula.
