Abstract

Patente de Invenção: "VáLVULA DE CONTROLE PARACOMPRESSOR DE DESLOCAMENTO VARIáVEL". Corpo deválvula (43) que ajusta a abertura de uma passagem de suprimento(28), em resposta à posição em uma câmara de válvula (46).Ummembro sensível à pressão (54) é movido de acordo com adiferença de pressão (PdH-PdL) entre dois pontos demonitoramento de pressão (p1, P2), que são localizados em umcircuito de refrigerante externo. O movimento do membro sensívelà pressão (54) afeta a posição do corpo de válvula (43), de talmodo que o deslocamento do compressor seja mudado parareduzir as flutuações na diferença de pressão (PdH-PdL). Umsolenóide (60) muda a força aplicada ao corpo de válvula (43), demaneira que seja mudada uma diferença de pressão ajustada, queé um valor de referência para mudar a posição do corpo de válvula(43) pelo membro sensível à pressão (54).
