In the drawings is shown a housing 1, torroidalnom cavity 2, the shaft 3, the drum 4, the shafts 5, 6 and 7, a pair of blades 8 and 9, 10 and 11, the housing 1 (round plates 12-13, conic sections 14-15 and the spherical portion 16), torroidalnom (circular) cylinder - 17, sector 18 and 19 of the housing 1, the guide 20, the ends 21 (shafts 5, 6 and 7), the rim 22, the holes 23 in the walls of the drum 4, a vertical partition formed by the plates 24 and 25, the transverse the horizontal slot 26, the annular guides 27, the output window 28 of the housing 1.

The rotary device includes a housing 1 formed by a spherical annular part 16 and end surfaces (sites 14-15, made in the form of a truncated cone, fastened with a broad base with the edges of the spherical portion 16 of the housing 1, and narrow base supplied with round plates 12 and 13 are placed in parallel the ends of the drum 4), thus formed torroidalnom cavity 2 which is placed in the shaft 3, is rigidly connected with the drum 4 through which pass (can be rotated) shafts 5, 6 and 7 with blades 8-9, 10-11. A pair of blades 8 and 9 and 10 and 11 rigidly fixed to the ends of the shafts so that the working plane of the blades 8 and 10 perpendicular to the working plane, respectively 9 and 11. Round plates 12 and 13, the tapered sections 14-15, the spherical portion 16 of the housing 1 and the drum 4 is formed in sector 18 torroidalnom cavity - torroidalnom (circular) cylinder 17, in which the blades 8-11 "work" as planar pistons. In sector 19 of the blade 9 is parallel to the median plane of the spherical part of the body (and at the same time the plane of rotation of the shafts 5,6) and supported by a section of the guide 20, located in a plane parallel to the median plane of the spherical part of the body, thus coaxially with her blade 8 in sector 18 is deployed perpendicular to the plane of rotation of the shafts 5,6. It is advisable to guide 20 has been fitted with roller track, which will reduce the friction on her blades. Guide 20 includes land located in a plane parallel to the median plane of the spherical part of the body, and upward part to the above plot, starting from the output window 28 of the housing 1.

In diametrically PLO the bones of the spherical surface part 16 of the housing 1 is fixed ring guides 27 which is placed between the rim 22, between the annular guide 27 with the possibility of pressure on the rim 22 and the free movement placed the ends of the shafts 21 of the shafts 5, 6 and 7, missed rotatably through openings 23, made in the walls of the drum 4.

A vertical partition formed by the plates 24 and 25 are bonded to the inner surface of the spherical portion 16 of the casing and tapered side surfaces 14 and 16 of its end parts. While facing each other of the edges of the plates 24 and 25 form a transverse horizontal slot 26 made with the possibility of passage through it of the blades 8-11 deployed parallel to the median plane of the spherical part of the body.

The housing 1 consists of two halves with flange mount 27 in the median plane (the plane passing through the axis of the shafts 5, 6 and 7.

The device operates as follows. The flow of the medium in torroidalnom annular cylinder 17 acts on the blade 8, propelling it, creates a torque on the shaft 3. Coaxially with her blade 9 when installed in parallel in the plane of rotation of the shafts 5, 6, is held in the slit 26 on the guide roller 20. From exit torroidalnom cylinder 17 of the blade 8 in the sector up to 60 from it unfolds upward section of the guide 20 and eventually turns the blade 8 is parallel to the plane of rotation of the shafts 5, 6, which is coaxial blade 9, unfolded perpendicularly to the plane of rotation of the shafts 5, 6, included in the toroidal cylinder 17. The presence torroidalnom cylinder 17 is always one blade dulls the shock effect of flow on incoming into the cylinder blade, which ensures smooth rotation of the rotor 2. The ends 21 of the shafts 5, 6, adjustably secured in the rim 22, relieve bending moments from the action of the flow on the blade in torroidalnom cylinder 17 in the mounting of the shafts 5 and 6 in bearings in a known manner specified in the holes 23, made in the walls of the drum 4. It converts energy of high-pressure fluids (steam, gas, etc.) into mechanical energy on the shaft PTO 3.

Education kinetic energy of the flow of mechanical energy using the claimed device is as follows. The flow is sucked in torroidalnom cylinder 17 of the blade 8 and pushes the portion of the environment in front of the blade 10 torque from the output shaft 3, provided by the transfer to it of the rotational motion from an external actuator (not shown). All subsequent turns and movements of the blades are identical, as described above.

The efficiency of our estimates is equal to 70%.

Installation confuser on the inlet flow low density of kinetic energy (the river flows, the IOE is the cue currents, wind and others) increases the speed of flow of the medium in torroidalnom cylinder 17, in cubic dependence increases the mechanical energy of the drop-off PTO 3.
