PURPOSE:To enlarge the absorption range of a turbine output by constituting a closed loop with the connection of the downstream side of an air cooler to the suction line of a compressor and also by providing a vacuum pump on a branch route of the downstream side of an air cooler of this closed loop. CONSTITUTION:The downstream side of an air cooler 17 is connected to the suction line of a compressor 8 and the spout line is connected to a pressure regulating valve 16, air cooler 17 and branch pipe 18 to constitute a closed loop, further another pipe aperture of the branch pipe 18 is connected to a vacuum pump 20 via a pressure regulating valve 19. The compressed air compressed by an air source 1 is adjusted to the specified pressure by a pressure regulating valve 4 and then sent to a turbine 6 of supercharger. The compressor 8 directly connected to the turbine 6 circulates the air of the inside of the above closed loop to absorb the turbine output. Consequently by changing widely from nearly vacuum to atmospheric condition the air density at the entrance of compressor the absorption range of a turbine output can be enlarged. |
