Abstract

"VALVULA DE CONTROLE PARA COMPRESSOR DE DESLOCAMENTO VARIáVEL". O compressor possui um carter (5), uma zona de descarga de pressão e uma passagem de alimentação (28). A passagem de alimentação (28) liga o carter (5) à zona de pressão de descarga. A válvula de controle é localizada na passagem de alimentação (28). O controle de válvula possui um corpo de válvula (41). O corpo da válvula (41) ajusta o tamanho da abertura da passagem de alimentação (28) de acordo com a pressão de descarga. O corpo da válvula (41) move-se de acordo com a pressão de descarga de modo que o deslocamento é variado para contrabalançar mudanças na pressão de descarga. A direção na qual o corpo da válvula (41) se move em resposta a um aumento na descarga é a mesma direção na qual o corpo da válvula (41) se move quando a pressão na passagem de alimentação aumenta.
