The invention relates to Masha is owano in road transport, as well as other mechanisms and machines.

Known scroll compressors, comprising a housing with supports under the bearings of the respective shaft - bearing and drive, the channels of the working fluid and the blower spiral displacer see , for example, PCT application 91/13240, F 01 C 1/4 from 05.02.91/.

Known engines, comprising a housing with supports under the bearings of the output shaft, the steam generator and expander /see, for example, patent RF N 1697481, CL F 01 C 1/04, from. 19.06.95/.

However, these engines have a number of disadvantages: low efficiency, large heat loss while supplying the working fluid to the engine, the low mechanical efficiency, the complexity of the design.

The objective of this invention is to provide a heat engine with higher efficiency, less heat loss in the process, more sophisticated, satisfying the requirements of the standards EURO-2, EURO-3 UNECE and expanding the Arsenal of technical tools used in engineering and, in particular, in engine.

To solve this problem is proposed rotary-spiral engine with external heat supply, comprising a housing with covers and supports bearing PTO, steam generator and expander. Reserialled axis with the same angular velocity by means of kinematic connection of a matching network. The rotors on my ends have a helical elements. The steam generator is located in the area of the poles of the spiral elements and in the form of a pipe, perforated directly at the entrance to the high pressure chamber of the expander, with a supply of coolant in the heat pipe located in the inner part of the housing of the steam generator, and the flow of the working fluid in the casing of the steam generator and then into the porous heat-conductive sleeve covering directly heat pipe.

To improve the technological and design parameters of the expander rotors can be made of composite primary drive and kinematically associated with the rolling disk, with the possibility of axial movement. The disc is made of a single spiral elements. The cavity between the base and a movable rotor disc sealed at the periphery and communicated with the high pressure chamber.

Spiral elements can be made consisting of a set of tapes, set in the rolling grooves of the rotor disc with the possibility of longitudinal movement during thermal expansion.

The invention is illustrated by the figures, where Fig. 1 - the proposed rotary-spiral motor /continue the capacity motor includes a housing 1 with lids 2 and 3, in which are mounted bearings 4 and 5 for installation of the rotor of the expander, consisting of the disks 6 and 7, kinematically connected through pins 8 with the movable disks 9 and 10. The rotors revolve around mutually parallel axes with the same angular velocity by means of kinematic connection of a matching network. The matching element is a rotor 11, kinematically linked with one hand through the pins 12 with the disk 6, and with the other hand firmly over the pins 13 with the disk 7. On moving the disks 9 and 10 mounted in grooves of the spiral elements 14 and 15.

Spiral elements 14 and 15 together with the movable disks form extender. In the area of the poles of the spiral elements 14,15 form a high pressure chamber, and on the periphery of the chamber extension. Between the movable disk of the rotor and the casing of the steam generator made the gap for the supply pressure of the working fluid in the cavity between the rotor disks to ensure that the efforts of the clamp, and the cavity has a ring seal on the periphery.

The steam generator 16 is placed directly in the area of the poles of the spiral elements 14, 15 and made in the form of a pipe, perforated in the high pressure chamber. Inside the steam generator is placed heat pipe body into the body of the steam generator.

The engine works as follows.

In the heat pipe 17 is supplied to the coolant, which can be used eutectic alloy NaKa. The coolant evaporates at the hot end of the heat pipe, placed in the heat exchanger of the combustion chamber (not shown) or heat the battery, and condenses at the cold end, placed in the steam generator 16. The heat released during condensation is transferred through the wall of the heat pipe porous sleeve 18 and then working body. As a working body can be used chemically pure water or another substance that meets the necessary requirements. After passing the working fluid through the perforated openings of the steam generator 16 in the high-pressure chamber, the working body, extending, affects the spiral elements and creates a torque, which is removed from the output shaft to the consumer.

In the proposed design supply thermal energy to the working body is in close proximity to area expansion, which minimizes heat loss along the "road" to the expansion mechanism. Because of the one-way movement of the working fluid gradient temperature field Poston using a piston mechanism as a steam engine.

This design provides continuous compensation of the clearance between the spiral elements and the rotor disk, which is provided by the mobility of the drive rotor in the axial direction and providing the pressing force by the pressure of the working fluid. This will increase the volumetric efficiency and reduce maintenance of the engine.

Rotor-piston rotating in cylinder is in contact with said flat surface. Working medium and pressure pass from working chamber of cylinder into balancing spaces found between ribbed base and ribbed platform through connecting channels in ribbed platform. Pressure on ribbed platform in working chamber is compensated by pressure on ribbed platform from balancing space. Pressing of ribbed platform to rotor-piston is provided by springs arranged between ribbed base and ribbed platform, and it does not change at changes of pressure in working chamber.
