VAPOR PARTICLE SEPARATOR
DRIVE
June 15, 2023
A vapor particle separator includes a housing having an inlet port in fluid communication with the outlet of the fuel tank, an outlet port in fluid communication with the inlet port of the vapor canister and a drain port in fluid communication with the filler neck. The inlet port has deflector ribs and a centralized nose cone creating a straight flow path resulting in less restriction in the fuel vapor flow. As the mixture flows along the inlet passage, it is forced through the deflection ribs and nose cone at which time the droplets and vapors are separated. The separated droplets and vapors flow from the inlet passage into the inlet pipe. The outlet passage and the drain portion allow the lite weight vapors to rise up into the outlet passage and out the outlet portion while gravity pulls the heavier weight droplets down into the return portion.
