  • Torque drive mechanism for gas compressor
    Patent number: 8317490
    Abstract: A torque drive mechanism for a gas compressor incorporates one or more air or gas engine starters to initiate rotation of a gas compressor and its associated driving electric motor. The air or gas engine starters are advantageously driven by natural gas from a supply pipeline, where the natural gas is present at sufficient pressure to drive the starters even before the natural gas is compressed.
