Abstract
The invention relates to a dual path dual purging system and valve assembly for turbo boosted engines. More specifically, the invention provides an integrated valve assembly connected to facilitate the operation of the low flow valve as a pilot valve for the high flow valve and a system to implement it on turbocharged or supercharged engines. The invention relates to a dual path dual purging system with two purge valves connected to facilitate the use of the low flow valve to be operated as a pilot valve for the high flow valve. This smart routing provides pressure compensation for the high flow valve, when the valve is enabled. This decreases the requirement of force for the high flow valve and gives an option to install a smaller cost efficient solenoid valve.
