  • Apparatus for storing and re-utilizing electrical energy produced in an electric power-supply network
    Patent number: 3988897
    Abstract: The output of at least the lowest-pressure turbo-compressor is connected via the intermediate cooler of the compressor group to the input of the turbo-compressor and a throttling means is placed in the conduit between the compressor output and cooler. The looping of the output to the input is effected to diminish the starting and idling power of the compressor group. Charging of the compressed air storage chamber is prevented by a check valve until the pressure of the pressure chamber is exceeded in the compressor group.
