<p>A Lysholm compressor comprises male and female rotors (1,2) which are rotatably accommodated within a casing structure comprising two part-cylindrical walls (9a,9b) which constitute a casing (3) and merge together at two cusps (10,11) which project inwardly towards one another. A suction port (4) and a discharge port (6) are provided at respective axial ends of the casing (3). A silencer chamber (13,14) is defined between at least one of the cusps (10,11) and respective associated outer wall portions (12, 15) which are situated outside the associated cusp and are integral with the casing (3). The or each silencer chamber (13,16) has a respective opening (14,17) which communicates with the suction port (4) and the discharge port (6), respectively. <IMAGE></p> |
