FIELD: machine building.
SUBSTANCE: invention relates to volumetric rotational devices with axes of rotation displaced with reference to collinear position and, in preferable variants, intersected in the central point. The indexing system for the rotor unit described by an ability to regulate an angular position of driving rotors, which in one version are configured with a possibility of rotation around the shaft.
EFFECT: invention is aimed at ensuring of a required mutual position of rotors in the rotor unit of the volumetric rotational device during their joint rotation.
