A compressed air reservoir is a critical component of a commercial vehicle’s braking and suspension systems. Located on the tractor or trailer, it stores pressurized air generated by the vehicle’s air compressor. This stored air is used to actuate the brakes, suspension, and other pneumatic systems. The size and number of these reservoirs vary depending on the vehicle’s configuration and application.
The reliable operation of these reservoirs is paramount to safety and efficiency. They provide a readily available source of pressure, ensuring consistent and effective braking performance, especially in emergency situations. Furthermore, they enable smooth suspension operation, contributing to driver comfort and cargo protection. Historically, these reservoirs have evolved from simple cylindrical designs to more complex shapes and materials to meet increasing demands for pressure capacity and durability.
