Abstract

filtro autolimpante para líquidos, particulamente para lubri-refrigerantes contendo partículas sólidas, compreendendo uma primeira câmara 13, comunicante com um duto lateral de entrada 8 do líquido a ser filtrado e possuindo uma válvula de fundo 3 e 4, e uma segunda câmara 20, comunicante com um duto de saída 21 e na qual é móvel um êmbolo 19. as duas câmaras 13 e 20 sâo entre elas comunicantes através de uma parede cilíndrica perfurada 10 e associado elemento filtrante 12. o duto de saída 21 inclui um tubo de descarga 23 que termina dentro do líquido filtrado contido em uma banheira de recolhimento 24 e possuindo um respiro lateral 28 disposto acima do nível máximo l do líquido filtrado na banheira de recolhimento 24. ao duto de entrada 8 está associado um defletor interno 9.a self-cleaning liquid filter, particularly for solid particle-containing lubricants, comprising a first chamber 13, communicating with an inlet side duct 8 of the liquid to be filtered and having a bottom valve 3 and 4, and a second chamber 20, communicating with an outlet duct 21 and in which a piston 19 is movable. the two chambers 13 and 20 are communicating therebetween a perforated cylindrical wall 10 and associated filter element 12. the outlet duct 21 includes a discharge pipe 23 which It terminates within the filtered liquid contained in a collection tub 24 and having a side breather 28 disposed above the maximum level 1 of the filtered liquid in the collection tub 24. Inlet duct 8 is associated with an internal baffle 9.
