Abstract (en)
[origin: EP2537984A1] It is provided a suction orifice (1) for suction machines (10) adapted to enable removal of refuse from streets and the like, comprising a first casing (2) adapted to substantially come into contact with the surface to be cleaned (S) and defining a first suction chamber (2a) adapted to be passed through by the refuse and a first inlet section (2b) adapted to enable the refuse to enter the first suction chamber (2a); and a choking element (5) adapted to partly overlap the first inlet section (2b) and defining a free section; and a passive actuation apparatus (6) adapted to define a slide path along which the choking element (5) is free to slide in an idle manner so as to vary its distance relative to the surface to be cleaned (S), thereby modifying the extension of the free section.
