FILTER FOR HYDRAULIC SYSTEMS HAVING PACKING WITH CONSTANT SIDE ACTION FOR THE SCREW-ON CARTRIDGE UNIT AND HAVING A GLOGGING INDICATOR RESPONDING TO DIFFERENTIATED PRESSURE

摘要

Filter for hydraulic systems, consisting of a holder (26) of a disposable cartridge (25), that can be screwed onto the head (10) to mount on piping serving the system, comprising an annular packing (15), between the head (10) and the holder (26) of the cartridge (25), having a transversal action in relation to the direction of screwing, and a clogging detector (40) sensitive to differences in pressure upstream and downstream of the head (10).
