Abstract
An automatic multi-air bag pneumatic inflation system for a trailer is also disclosed. The inflation system includes a system control unit coupleable to an air supply for controlling the flow of pressurized air in the pneumatic inflation system. The system control unit comprises an inlet for coupling to the air supply with an on/off valve for providing a flow of air, a primary regulator in communication with the flow of air and the on/off valve, an inflation pressure tank in communication with the flow of air and the primary regulator, a control valve in communication with the inflation pressure tank and/or primary regulator, and used to control the air flow, a function selection valve for selecting between inflation and deflation, and an outlet. A plurality of fill stations are fluidly coupled to the system control unit. One or more fill stations of said plurality of fill stations are fluidly coupled to an air bag for inflation and deflation thereof. The fill stations may include a manifold block, including a first inlet/outlet for fluidly coupling to the system control unit for transmission of the air supply, a safety relief valve joined to the manifold in fluid communication wit…
