Patent ID: 10871160

Abstract:
Volumetric compressor (1) for collection and/or treatment equipment of material in liquid, solid, dusty or muddy form. The compressor (1) comprises an operative chamber (50), defining a suction section and an exhaust section of a first fluid, a first header (61) and a second header (62), which delimit said chamber (50) on opposite parts along a longitudinal axis (101). The compressor further comprises at least two rotors (80′, 80″) with lobes (81′, 81″) housed in the chamber (50), each rotor (80′, 80″) rotating about a rotation axis (108′, 108″) substantially parallel to said longitudinal axis (101). The lobes of each rotor develop according to a helical profile. Furthermore, each of the headers (61,62) defines at least one injection opening (71′, 71″,72′,72″) communicating with a feeding device (150) of a second fluid.
