Abstract

"VáLVULA DE CONTROLE PARA COMPRESSOR DE DESLOCAMENTO VARIáVEL". Usada em um compressor de deslocamento variável. O compressor possui um cárter (5) e uma passagem de alimentação (28). A válvula de controle é (46) inclui uma carcaça de válvula (45). Um corpo de válvula (43) é acomodado na câmara de válvula (46) para ajustar o tamanho da abertura da passagem de alimentação (28). Um elemento sensor de pressão (54) divide a câmara sensora de pressão (54) em uma primeira câmara de pressão (55) e uma segunda câmara de pressão (56). A pressão no primeiro ponto de monitoração de pressão (P1) é aplicada à primeira câmara de pressão. A pressão no segundo ponto de monitoração de pressão (P2) é aplicada à segunda câmara de pressão (56). O elemento sensor de pressão (54) move o corpo da válvula (43) de acordo com a diferença de pressão entre a primeira câmara de pressão (55) e a à segunda câmara de pressão (56). O elemento sensor de pressão (54) é um fole ou um diafragma. Um solenóide (60) aplica força ao elemento sensor de pressão (54) de acordo com comandos externos. A força aplicada pelo solenóide (60) corresponde a um valor de referência de diferença de pressão. O elemento sensor de pressão (54) move o corpo de válvula (43) de modo que a diferença de pressão busca o valor de referência.
