Abstract

Filtru autopurifiant care conţine corpul filtrului şi, cel puţin, o gură de intrare pentru lichid impur şi o gură de ieşire pentru lichid pur, mediul filtrant, plasat între gurile de intrare pentru lichid impur şi ieşire - pentru lichid pur. Cel puţin, un injector este plasat în apropierea nemijlocită de mediul filtrant şi este cuplată cu, cel puţin, două surse diferite de presiune, în plus una din aceste presiuni este mai mare decât presiunea predominantă în filtru, iar altă presiune este mai mică decât cea predominantă în filtru. Tot aici este asigurat un dispozitiv pentru crearea mişcării relative între mediul filtrant şi, cel puţin, un injector pentru a avea o porţiune esenţială a ariei suprafeţei mediului filtrant cuprinsă de acest injector.
