Abstract: 1. Volumetric device, containing a body fitted with bearing supports, and a working member mounted inside the body, provided with meridianal cavities and contactors mounted with the possibility of azimuthal traveling, placed in meridianal cavities with forming working chambers and mounted with the possibility of azimuthal traveling on the bearing supports with the possibility of azimuthal traveling, gearing elements of the working member and elements of a conductor of working medium, characterized in that the contactors are mounted in such a way that it is possible to ensure a permanent interaction thereof with the bearing supports during the azimuthal motion of said contactors. 2. Volumetric device according to claim 1, characterized in that the mounting of each contactor is made by means of placed in contactor azimuthal guide, interacting with slider, mounted with the possibility of turning on bearing supports. 3. Volumetric device according to claim 2, characterized in that each slider is made in form of prismatic body, cylindrical and plain surfaces of it being covered with antifriction material. 4. Volumetric device according to claim 2, characterized in that each slider is made in form of roller. 5. Volumetric device according to claim 4, characterized in that the roller is barrel-like. 6. Volumetric device according to claim 4, characterized in that the roller consists of middle and two lateral parts, guide is made with the possibility of contact of one side with middle part of roller and of another part - with lateral parts, all parts of roller are mounted with the possibility of independent rotation. 7. Volumetric device according to claim 2, characterized in that the slider is formed by plane areas of rotation surface, diameter corresponding to width of meridianal cavity. 8. Volumetric device according to claim 2, characterized in that the guide is made in form of plate, ends being mounted in contactor, and each slider - as 2 bushes, placed in bearing support bore, middle part of the plate being placed between the bushes and the bore is provided with windows for the passing of ends of plates. 9. Volumetric device according to claim 1, characterized in that the mounting of each contactor is made by direct accommodation of contactor with the possibility of turning on bearing support, said contactor being made in form of eccentric, central part of it being displaced in meridianal direction and passed through the center of a spherical motion of the working part, and diameter of eccentric corresponds to the width of meridianal cavity. 10. Volumetric device according to claim 1, characterized in that mounting of each contactor is made by direct accommodation of contactor with the possibility of turning on bearing support, said contactor being made in form of couple of coaxial eccentrics, central axes being symmetrically spased in meridianal direction and passed through the center of a spherical motion of the working part, and diameter of eccentric corresponds to the width of meridianal cavity. 11. Volumetric device according to claim 1, characterized in that that mounting of each contactor is made by means of a link, connected by joint connection by one end with bearing support, and by another end - with finger, fixed in contactor, finger axe being displaced in meridianal direction and passed through the center of a spherical motion of the working part. 12. Volumetric device according to claim 1, characterized in that mounting of each contactor is made by means of double-crank arm, placed in bearing support with the possibility of turning, said arm having a support on each end, and contactor consists of two similar parts, interconnected by elastic connection, each part being provided with holder with a heel, interacting with support along the spherical surface is placed on geometrical axis, passing through the center of spherical motion of the working part and middle of meridianal cavity at the extreme position. 13. Volumetric device according to claim 12, characterized in that the supports are made in form of plano-convex lens, mounted by plain surface on the ends of arm with the possibility of traveling.
