ABSTRACT:
There is designed an equipment with mutually interacting spiral teeth, comprising at least two spiral rotors seating in a stator, where surfaces of the rotor shafts, a rotation wrapper of each of the rotors, each one being furnished with at least one spiral tooth, and a shape of the stator inner further are created by a rotation of a combination of curves having convex and/or concave shape, the curve waveform being defined by shapes of the spiral teeth profiles and their thread lead, provided the spiral teeth profiles and their thread lead, as presented in any section perpendicular to a longitudinal axis of the rotors, are created in relation to required values of pressure, volume and velocity of a media in any part of a working space within the section, the working space being defined as intermediate space between respective spiral rotors themselves and between the rotors and the stator, while the spiral teeth manifest leads of the same or opposite sense.
