Abstract
A deflector mounts a carbon scrubber element at an atmospheric port of an evaporative emissions canister. A substantially cylindrical shell has an open end and a closed end. A spacer plate extends outwardly from the shell. An elastomeric ring is overmolded within the shell at a longitudinal position between the ends. The elastomeric ring has an inner diameter configured to sealingly receive the carbon element. A plurality of vapor apertures are formed in the shell between the spacer plate and the elastomeric ring. A plurality of elastomeric ribs are overmolded by the interior surface within the shell the vapor apertures and the closed end, and are configured to be spaced around the carbon element to suspend the carbon element spaced away from the shell without blocking a gaseous flow from the vapor vents to the carbon element.
