There is designed an equipment with mutually interacting spiral teeth, comprising at least one rotor and one stator with a working surface limited by at least two sprial teeth, which are in mutual interaction by their wrappers and the spiral teeth, being wound-up on shaft surfaces, thus creating rotors, or simultaneously on a surface of at least one shaft, thus creating a rotor, and also on an inner stator surface, provided the spiral teeth have the same or opposite sense of thread lead with, a constant or variable lead angle while the axes of rotations of mutually interacting spiral teeth are parallel or concurrent or skewed, where at least a part of a rotation wrapper of the first-rotor shaft (21) of at least one of the first rotor (2) is created by a rotation of a curve around the axis of the first-rotor shaft (21), the curve being concave or convex to the rotating axe of the first-rotor shaft (21) and at least part of the surface is concave or convex with respect to the rotating axis of the said stator (1) inner space and is represented by a shape of a rotation wrapper of the first rotor (2).
