The group of inventions relates to mechanical engineering, and in particular to rotary machines, pumps, hydraulic motors and engines. A rotary-vane machine comprises two circuits of working chambers: a first, with a variable working volume between the vanes; and a second, with a variable working volume of compartments which are divided by a piston-like shaft, with different combinations depending on the function, i.e. an engine or a pump. During operation of the rotary-vane machine according to a first variant, an engine operating stroke is provided in each separate vane across the complete circumference of rotation, as well as the possibility of starting up same without additional external devices; and during operation according to a second variant, a pump of each vane, from an intra-vane chamber via a piston-like shaft, provides for uninterrupted suction and simultaneous uninterrupted delivery of a working medium, which enables it to be used as a constant pulling force, for example, in water and in air. During operation of the rotary-vane machine according to a third variant, the volume of an inter-vane chamber and the volume of one of the compartments of the intra-vane chamber are combined via a vane channel, which makes it possible to increase the torque-carrying capacity of the vane as a result of the working pressure. |
