Abstract

"DISPOSITIVO DE CONTROLE PARA COMPRESSOR DO TIPO DESLOCAMENTO VARIáVEL". Um dispositivo de controle inclui uma primeira passagem, uma segunda passagem, uma terceira passagem, uma válvula de controle de deslocamento e uma válvula auxiliar. A válvula de controle de deslocamento é colocada na primeira passagem. A válvula auxiliar inclui uma câmara de válvula, uma válvula de carretel e um dispositivo de impulsão. A válvula de carretel é deslizavelmente acomodada na câmara de válvula. A válvula de carretel divide a câmara de válvula em uma primeira câmara de pressão e uma segunda câmara de pressão, para comunicar a primeira câmara de pressão com a primeira passagem e para comunicar a segunda câmara de pressão com a segunda passagem. O dispositivo de impulsão é colocado na câmara de válvula para impelir a válvula de carretel em direção à primeira câmara de pressão. A terceira passagem se comunica com a primeira câmara de pressão e/ou a segunda câmara de pressão pelo movimento da válvula de carretel.
