Реферат: The present invention concerns a volumetric compressor (1) that can be used, preferably, for producing equipment and/or a plant for the suction of material in liquid, solid, powder or slurry form. The compressor according to the invention comprises a body (2) defining an operative chamber (5), a suction section (51) and a discharge section (52) of an operating fluid. The compressor further comprises at least two lobe rotors (8A, 8B), the lobes (81A, 81B) of which are housed inside said operative chamber (5), each rotor (8A, 8B) rotating around a corresponding longitudinal rotation axis (101A, 101B). The compressor comprises a first header (6) and a second header (6' ) which delimit on opposite sides the operative chamber (5); each header comprises a bank (61, 61') connected to the body (2) and configured to support the rotors (8A, 8B) and a cover (62, 62' ) connected to the bank (61, 61') so as to define an inner volume (65, 65' ) comprised between the cover (62, 62' ) and the bank (61, 61') and designed to house, in use, a lubricating bath. According to the invention the compressor comprises a generator unit for generating a forced flow of cooling gas and, for at least one of the headers (6, 6' ), the bank (61, 61' ) defines a cooling chamber (70, 70' ) physically separated from the operative chamber (5) and from the inner volume of lubricant. Said chamber (70, 70' ) comprises an inlet (71, 71') and an outlet (72, 72' ) for a cooling gas, where said inlet communicates with the generator unit of the forced flow of said cooling gas.
