<p>A screw compressor comprises a casing (1) defining therein a pair of cylindricyl chambers (14, 15) intersecting with one another parallel to their axes and a pair of male (4) and female (5) screws in an intermeshing relationship. The casing (1) includes an inlet port (20) composed of an open area fully open to the chambers (14, 15) except for seals (22) around the shafts (40, 50) of the screws (4, 5), the profile of the inlet port (20) being equal to the profile of the chambers (14, 15), such that the fluid can flow freely into said chambers (14, 15) without turbulent fluid flow.</p> |
