Abstract
Official abstract text for this publication.
An integrated canister purge valve for a turbocharged vehicle engine includes a valve member 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. Structure separating the interior space into a first chamber and a second chamber isolated from the first chamber. The first chamber has an inlet port and an outlet port. A vacuum generator is provided in the first chamber and in fluid communication with the inlet and outlet ports. A first check valve is in the first chamber between the vacuum generator and the valve member and a second check valve is in the second chamber between the valve member and a manifold outlet port.
