Abstract

atente de Invenção: <B>"VáLVULA DE ESFERA DE COMPRESSOR"<D>. Trata-se de um compressor de refrigerante(20), em que uma montagem e válvula de descarga (43) reduz o volume de reexpansão. A presente invenção proporciona um montagem de válvula de descarga (43) para tipos de compressores alternativos, rotativos e espiral e inclui um elemento de válvula esférico (44) que engata e penetra em uma porta de descarga (40) proporcionada em um cabeçote de cilindro de compressor (38), placa de válvula ou placa de espiral. A porta de descarga é formada no cabeçote do cilindro ou placa espiral e é dimensionada de tal modo que o elemento esférico penetre e substancialmente preencha a porta de descarga. O volume de reexpansão dentro da porta de descarga, deste modo, é reduzido. Para manter o engate do elemento esférico com a porta de descarga, um braço deformável elasticamente (46) tendo uma abertura (48) é posicionado para segurar o elemento esférico na porta de descarga. O braço é deformável elasticamente para permitir que o elemento de válvula esférico se mova para fora de engate com a porta de descarga durante a fase de compressão do compressor. Para impedir que o elemento de válvula esférico seja descarregado junto com o refrigerante comprimido, uma placa de batente rígido (50) é disposta adjacente ao braço deformável para engatar o elemento esférico durante a fase de compressão e assim, limitar o movimento do elemento de válvula esférico.
