Beschreibung
Zusammenfassung:	A screw machine is primarily designed for drilling oil and gas wells. The screw machine comprises consecutively mounted screw mechanisms incorporating coaxially arranged stators and rotors disposed therein whose axes are displaced with respect to the central axis of the stators to the value of eccentricity "e" of the screw mechanisms. The screw mechanisms are grouped into modules and the modules are grouped into blocks. The axes of the rotors of the screw mechanisms in the module and the modules proper in the block are arranged symmetrically relative to the central axis.
