Abstract:
1. A rotor sliding-vane machine with adaptive rotor comprising: a housing with an inlet port, an outlet port, a supporting cover plate and a working cover plate having a forward transfer limiter and a backward transfer limiter; a rotor, comprising a working part of the rotor with vane chambers, while a working face surface of said working part of the rotor has an annular groove connected to vane chambers containing vanes that are kinematically connected to a vanes drive mechanism mounted on the housing; while the working cover plate of the housing being in sliding sealing contact with the working face surface of the working part of the rotor forms a working chamber in the annular groove, so that the working chamber is divided by the backward transfer limiter being in sliding sealing contact with a rotor means of backward transfer insulation and by the forward transfer limiter being in the sliding sealing contact with the vanes into: a suction cavity of the working chamber hydraulically connected to the inlet port and a pumping cavity of the working chamber hydraulically connected to the outlet port, while the forward transfer limiter and the vanes drive mechanism are made so that the vanes separate at least one inter-vane cavity of the working chamber from the pumping and suction cavities, wherein the rotor also comprises: a supporting part of the rotor being in sliding sealing contact with the supporting cover plate of the housing and kinematically connected to the working part of the rotor by an assemblage of rotor elements, including force chambers of variable length so that to rotate synchronously with the working part of the rotor allowing axial travels and tilts relative to the working part of the rotor to provide a sliding sealing contact of both the working part and the supporting part of the rotor with the corresponding cover plates of the housing, while changing the length of the force chambers of variable length leads to said axial travels and tilts of the working and supporting parts of the rotor, while supporting cavities provided with sealing means are made between the supporting cover plate of the housing and supporting part of the rotor, while each of the said cavities of the working chamber hydraulically communicates with at least one force chamber of variable length and with at least one supporting cavity via means of local pressures balancing.
