Abstract:
1. Filtering unit ( 10 ) comprising a casing ( 20 ) provided with at least one inlet ( 32 ), one outlet ( 33 ) and one support body ( 42 ) provided with abutment surfaces ( 44 ) adapted to removably support a filtering cartridge ( 50 ) contained within the casing ( 20 ) and adapted to divide the internal volume of the casing ( 20 ) into two chambers ( 21 , 22 ) respectively connected with the inlet ( 32 ) and the outlet ( 33 ) so as to filter the fluid flowing from the inlet ( 32 ) towards the outlet ( 33 ), the filtering cartridge ( 50 ) comprising at least one coupling element ( 55 ) configured to be snap-coupled to the support body ( 42 ) following a first axial translation for mutual approaching between the filtering cartridge ( 50 ) and the support body ( 42 ), the filtering unit ( 10 ) comprising cam means ( 57 , 58 ) operating between the coupling element ( 55 ) and the support body ( 42 ) so as to radially bend the coupling element ( 55 ) in a release position for disengaging the coupling element ( 55 ) from the support body ( 42 ) following a further limited mutual axial translation between the filtering cartridge ( 50 ) and the support body ( 42 ), moving in the same direction with respect to the first approaching translation, the cam means ( 57 , 58 ) being configured so as to keep the coupling element ( 55 ) in a release position following a slight mutual rotation between the filtering cartridge ( 50 ) and the support body ( 42 ).
