Abstract:
1. A rotary working machine provided with an assembly of working chambers with periodically variable volume, comprising: a stator with at least one controlling cam located on an outer surface of the stator and a surrounding cylindrical rotator comprising a set of oscillating working elements provided within a plurality of cylindrical sockets on an inner surface of the cylindrical rotator to enable oscillatory motion of the set of oscillating working elements, wherein the set of oscillating working elements are driven by the controlling cam on an stator outer surface, wherein an inner surface of the cylindrical rotator and an outer surface of the controlling cam define a plurality of working chambers with a variable volume that are each connected during the rotation of the cylindrical rotator with an intake and an outlet for a medium being compressed, wherein the outline of the controlling cam constitutes a line equidistant from a curve comprising the range of the points XQp) and Y(p) which are described by the parametric equations: further comprising a locus of points forming a closed trajectory on an immobile plane perpendicular to the axis of the cylindrical rotator, by the vertex point of the working elements moving in relation to the rotator in an oscillation with a resonance frequency during one full revolution of the cylindrical rotator, wherein an inertia moment of the working elements are provided in parallel to an oscillation axis to obtain a resonance frequency of proper vibration of the set of oscillating working elements in relation to the cylindrical rotator as expressed by the following equation: wherein a ratio of the resonance oscillation frequency to a frequency of rotation of the cylindrical rotator is expressed by a constant natural number.
