These reservoirs are vital components of a vehicle’s pneumatic braking system. They store compressed air, providing the necessary pressure for brake application. Properly sized and maintained, these tanks ensure adequate air volume is available for repeated braking, even when the compressor output is temporarily limited.
Their presence is critical for safety, especially in heavy vehicles like trucks and buses. They provide a reserve of compressed air, allowing the vehicle to stop safely should the compressor fail or when demands exceed supply during frequent stops. The development and refinement of these storage units have significantly contributed to the enhanced reliability and stopping power of modern air brake systems, reducing the risk of accidents.
