A rock drilling rig and method of driving compressor

摘要

The invention relates to a rock drilling rig and a method of driving a compressor. The rock drilling rig (1) is combustion engine (DI) operated and is provided with a flushing system (FS) including a compressor (CO) for producing pressurized air. The compressor is driven by an electric drive motor (CM). The combustion engine is connected to drive a generator (GEN) which produces electric energy that is stored in an energy storage (BAT). The stored electric energy can be utilized in driving the compressor.
