Abstract:

A vacuum solenoid valve may comprise a valve body defining an interior cavity and include a plurality of ports configured to be in fluid communication with the interior cavity of the valve body. One or more valve seats may be disposed about an opening between at least one of the plurality of ports and the interior cavity. One or more valve members may be configured to be moveably disposed within at least a portion of the interior cavity of the valve body and to sealingly engage with the valve member.

Abstract:

An auxiliary fuel vapor adsorption device includes a housing and an activated carbon segment contained within the housing and including a quantity of activated carbon material. A dust separator is also contained within the housing and in fluid communication with the carbon segment, and a canister vent valve is mounted to the housing in fluid communication with the activated carbon segment. The invention allows for the reduction of evaporative emissions by minimizing interconnecting joints between necessary fuel system components.
