A screw compressor having an adjustment slide equipment for adjusting discharge pressure and capacity, respectively, is designed in an advantageous manner in that there is used a "large slide" (24), which is longer than the compressor screws (4, 6) and thereby, via a pointed end portion (14) and in connection with an axial displacement, is operable to effect pressure adjustment at the discharge port (10) without affecting the conditions at the intake end; at the latter, a capacity adjustment can be effected by means of an auxiliary slide (26) which, seen in cross section, forms part of the large slide, and which is separately axially displaceable in a groove (30) therein, such that it is possible to open this groove to a variable degree towards the meeting area of the screw rotors. This basic design in connection with an unusually large diameter of the main slide (24) provides for several advantageous possibilities discussed in greater detail.
