ABSTRACT:
A fire extinguishing apparatus is connected to the safety valve on an oil flooded rotary compressor to receive the contents expelled by the compressor due to internal combustion in the compressor. The contents are conducted to the fire extinguishing apparatus, which disperses them in a tank holding a quantity of non-combustible liquid sufficient to cool them. The fire extinguishing apparatus has a tank for holding non-combustible liquid, a perforated plate to disperse the burning oil and gases throughout the non-combustible liquid, an opening to allow the escape of excess pressure from the tank, and a spring loaded lid to prevent evaporation of the non-combustible liquid. A pipe connects the fire extinguishing apparatus to a safety valve and the pipe has temperature and pressure switches on its surface which shut down the compressor when the temperature and/or pressure in the pipe exceed preset limits.
