  "abstract": "A conveyor drive roller for a conveyor system. The conveyor drive roller has a hollow drum rotatably connected to a first stationary shaft and a second stationary shaft, and defines a sealed chamber. The chamber at least partially encloses means to rotate the hollow drum about the first and second stationary shafts. A pressure relief valve is positioned on the conveyor drive roller in fluid communication with the inside of the chamber. The pressure relief valve is configured to reduce a gas pressure increase inside of the chamber caused by a rise in a temperature of the conveyor drive roller during operation.",
