    The invention relates to mechanical engineering, namely to screw rotor mechanisms. A pair of interlocking rotors containing helicoidal teeth are associated with the last troughs, while the teeth have front and rear surfaces with portions located outside the starting circle and inside it, and the leading rotor inside the starting circle has a smaller portion than the twist and - outside it is smaller than inside, and the profiles of the front surface of the driven rotor and the rear lead have a common point of contact located on the initial circumference of the driven rotor. ij A disadvantage of the known construction is the difficulty of making the teeth. The purpose of the invention is to simplify the design and increase reliability. This goal is achieved by the fact that there are cavities in a pair of interlinked rotors containing helicoidal teeth adjacent to the latter, while the teeth have front and rear surfaces with portions located outside the initial circle and inside it, and the leading rotor inside the initial circumference has a smaller area than the outside and the follower has less outside than inside the profiles of the front surface of the driven rotor and the rear lead have a common touch point J located on the initial circle of the driven rotor, its surface situated inside the circle starting each tooth of the male rotor, in cross-section is formed in a straight, coinciding with the rotor radius drawn to the point of intersection of the profile with tooth pitch circle. In addition, a section of the front surface located inside the starting circle of each tooth of the driven rotor, in cross section 40 from the point of contact of the teeth located on the starting circle of the driven rotor, is made along a straight line coinciding with the radius of the driven rotor . FIG. 1 shows a pair of interlocking rotors in FIG. 2 - profile of interacting rotors. A pair of interlocking rotors 1 and 2 contains helicoidal teeth 3 and 4, which are adjacent to the last depressions 5, while teeth 3 and 4 have front and rear surfaces 6, 7 and 8, 9 with sections In, cd, ab and kl, ran, ad located outside the initial circle and inside it, with the leading rotor 1 inside the initial circle O, the ki section is smaller than the outside, and the slave 2 has less outside than the inside, and the front surface profiles 7 of the driven rotor 2 and the rear surface 8 of the leading have point 10 touch located on the initial circle 0 of the slave ro torus 2. The rear surface part im, located inside the initial circumference Oj of each tooth 3 of the leading rotor 1, is made in cross section along a straight line coinciding with the radius t of the rotor 1, drawn to the point 11 of the intersection of the tooth profile 3c with the initial circumference Oj. The front surface area ae, located inside the initial circle O5 of each tooth 4 of the driven rotor 2, in cross section from the point 10 of contact of the teeth 3 and 4 located on the starting circle Oj of the driven rotor, is made along a straight line coinciding with the radius g of the driven rotor 2 , conducted to the point of 10 contact. During the operation of the machine and the rotations of the rotors 1 and 2, the gas is compressed and supplied to the consumer. The implementation of a pair of interconnected rotors by the proposed O-Braz makes it easy to process them on a gear-cutting machine, and also increases the reliability of operation due to the unaccented operation of the mating rotors.
