HEAT-INSULATING AIR-POWERED DRIVE Russian patent published in 2009 - IPC F04B19/24 

FIELD: motors and pumps.

SUBSTANCE: air-powered drive relates to positive displacement compressors with heat-employing drive. The air-powered drive comprises a housing 1 divided into service capacity 3 and semi-spherical hyperbaric chamber containing inlet 6 and outlet 7 valves by elastic membrane 2. The service capacity is partially filled with light-volatile liquid 4. The lower point of service capacity 3 is connected to pipelines 8, 9 and 10, having automatic check valves 11 and 12. One valve 11 is attached to one side of the reversible pump 13, whereas the other valve 12 is coupled with the heater outlet 14. Reversible pump 13 is connected with the cooler 15 by its other side. The heater 14 and cooler 15 are interconnected through heat generator 16. The reversible pump 13 is controlled by the line 17 from pressure sensor 18 installed in the service capacity 3. The place of check valve 11 connections to reversible pump 13 is coupled with the pipeline 19 through the check valve 20 and pipeline 21 and to the header 22 provided with injectors for liquid 4 The heater is position in the upper part of service capacity 2 The connection point of check valve 12 and heater 14 is also connected to the header 22 with injectors for liquid 4 through the check valve 24 and pipeline 21 The technical result of the invention is the simplification of design, increase of output, improvement of heat generating conditions.

EFFECT: simplification of design, increase of output, improvement of heat generating conditions
