Abstract

"VáLVULA DE CONTROLE PARA COMPRESSOR DE DESLOCAMENTO VARIáVEL". Que possui uma carcaça da válvula (45). Uma câmara da válvula (46) e uma câmara sensora de pressão (48) são construídas na carcaça da válvula (45). Um elemento sensor de pressão (54) está situado na câmara sensora de pressão (48). Um pino sensor de pressão (41) é suportado pela carcaça da válvula (45) de modo que possa deslizar. Um corpo da válvula (43) está situado na câmara da válvula (46). Uma extremidade do pino sensor de pressão (41) é conectada ao elemento sensor de pressão (54) e a outra extremidade do pino sensor de pressão (41) entra em contato com o corpo da válvula (43). Uma câmara do solenóide (63) está situada na carcaça da válvula (45). Um núcleo fixo de ferro (62) está localizado entre a câmara da válvula (46) e a câmara do solenóide (63). Um pino do solenóide (40) estende-se através do núcleo fixo de ferro (62) e é por ele suportado de modo que possa deslizar. Uma força aplicada ao elemento sensor de pressão (54) por um atuador, através do pino do solenóide, corresponde a um valor de referência da diferença de pressão. O elemento sensor de pressão (54) move o corpo da válvula (43) de modo que a diferença de pressão busca o valor de referência.
