2722CD - August 2012

Coach number 1722 is fitted with air assisted suspension. This means that in addition to the usual traditional arrangement of leaf springs, air bellows fitted to the axles provide a smoother ride. As the vehicle travels along, a system of valves regulates the amount of air in the bellows thereby adjusting the cushion effect to give the best ride. One such valve is seen below:


The lever to the left attaches to a rod connected to the axle. As the axle moves up and down over the surface of the road, the lever is agitated and controls the air flow. These valves require occasional reconditioning and this task has recently been completed. The valve pictured above is seen again below after having been refitted to the coach.
