Abstract (en)
[origin: WO2013187912A1] An integrated canister purge valve (10) for a turbocharged vehicle engine includes a valve member (34) having a housing and being constructed and arranged to control vapor purge flow from a fuel tank and canister structure to an air intake manifold. A body is coupled to the housing. The body defines an interior space (15). Structure (16) separating the interior space into a first chamber (20) and a second chamber (22) isolated from the first chamber. The first chamber (20) has an inlet port (21) and an outlet port (23). A vacuum generator (12) is provided in the first chamber (20) and in fluid communication with the inlet and outlet ports. A first check valve (36) is in the first chamber (20) between the vacuum generator (12) and the valve member (34) and a second check valve (38) is in the second chamber (22) between the valve member (34) and a manifold outlet port (28).
