Diverter Valve: Notes
After the air leaves the air pump, it goes immediately into the diverter valve. This valve serves to prevent backfire by stopping air injection flow during deceleration). The diverter valve will dump the air supply to the atmosphere for the first few seconds of deceleration. Most diverter valves also have a pressure relief valve which bleeds off excessive air pump pressure to prevent damage to the system. Diverter valves used on many applications are similar to the one shown. See Fig 1.
