Abstract

"COMPRESSOR COM MODULAçãO DE CAPACIDADE DE SUCçãO BLOQUEADA". A invenção refere-se a um sistema de controle de capacidade tem uma válvula que fecha a entrada para um ou mais dos cilindros em um compressor de cilindros múltiplos. A válvula é motivada através de fluido em pressão de descarga que reage contra um pistão para fechar a entrada. Um orifício é posicionado no fluxo de fluido na pressão de descarga para controlar a velocidade do pistão para reduzir o carregamento de impacto e aperfeiçoar a confiabilidade.
