Abstract
Disclosed is a screw compactor comprising two screw rotors which are disposed in screw rotor bores inside a compressor housing and compress a coolant that enters at a coolant inlet and discharge said coolant at a coolant outlet, and a coolant inlet that is arranged within the compressor housing, said coolant being supplied by a coolant-injecting device via a conduit system in order to additionally cool the screw compressor. The inlet is disposed so as to extend into compression spaces that are enclosed by the screw rotors and the screw rotor bores. The aim of the invention is to create a screw compactor in which the compressive oscillations occurring at the inlet do not travel at all or only in an attenuated manner into the conduit system for the coolant-injecting device. Said aim is achieved by mounting a first inlet duct section which runs inside the compressor housing upstream of the inlet, an injection port for the coolant that is supplied by the coolant-injecting device extending into said first inlet duct section, while making a cross-sectional area of the injection port more than about four times smaller than a cross-sectional area of the first inlet duct section.
