Abstract
<B>"VáLVULA DE DESCARGA DE UM REFRIGERADOR INTERMEDIáRIO"<D>. A presente invenção trata de um aparelho para um rapidamente descarregar a pressão de ar um refrigerador intermediário, pneumaticamente conectado, para receber ar comprimido de um compressor. O aparelho inclui uma válvula de descarga, pneumaticamente conectada, para receber pressão de ar contida no refrigerador intermediário. A válvula apresenta uma grande abertura de descarga e um elemento de válvula, que pode ser assentado contra a abertura para abrir e fechar a mesma. Uma abertura de admissão é fornecida para admitir um sinal de descarregamento do compressor para a válvula, com o sinal de descarregamento sendo efetivo para deslocar o elemento de válvula de grande abertura de descarga, de modo e permite um rápido descarregamento de pressão de ar do refrigerador intermediário para a atmosfera, através da abertura de descarga.
