<p>The invention relates to mechanical and power engineering and to shipbuilding and can be used for power supply to high-power devices, for example the propeller shafts of ships, industrial electric generators and the similar technical devices. Said invention makes it possible to improve the power and operational parameters of an electrodynamic rotary machine. The inventive electrodynamic rotary machine (1) comprises a closed hydraulic circuit (3) with pumps (34, 47) and a rotary engine (2), in the body (6) of which a shaft (7) with a rotor (8) are mounted. At least four decompression chambers (10) with intake channels (11) are made on the cylindrical surface of the rotor (8). Output channels (23) are made in the body (6) and are connected to an annular gravitation chamber (12) which is located around the rotor (8) between the body (6) and an assembly annular shell (13) in the form of at least four segments (14). The cross-sections of the decompression chambers (10) of the rotor (8) are designed in the form of truncated cones with an apex angle ranging within a = 19-22°, wherein the small base of the chamber cone is conjugated with the input channel and a distance d between the small and large bases of the cone of the chamber (10) is not less than 14-16% the length of the input channels (11), said channels being functionally connected to the hydraulic storage-collectors (31). The output channels (25) with pipelines (27) are connected, via an output manifold (26), to a circulating tank (28) which is coupled, by means of the system of pipelines (38, 40), provided with primary (39) and secondary (41) filters, and high-pressure pumps (34) with an independent electrical drive, to the hydraulic storage-collectors (31).</p> |
