Abstract

There is described a compressor device (13) for a pressurization system (12) of a packaging machine (1) configured to produce packages (2) starting from a tube (3) of packaging material, the compressor device (13) comprises an impeller (16) and a casing body (17) internally defining an impeller vane (18) and a receiving seat (19) for the impeller (16), the impeller (16) and the receiving seat (19) are separated by a gap (24) which fluidically connects the impeller vane (18) with an external environment (50) outside of the compressor device (13) for allowing the passage of air in overpressure from the impeller vane (18) through the gap (24) and towards the external environment (50); the compressor device (13) comprises a seal member (25) arranged at said gap (24), the seal member (25) is configured to be controlled in: an opening position, in which it delimits a passage together with said impeller (16) or said receiving seat (19) for allowing the passage of air in overpressure through the gap (24); and a closing position, in which it fluid-tightly seals the gap (24).
