Claim Text:
1. A dampening fluid delivery device, comprising: a dampening fluid supply chamber; a dampening fluid supply channel positioned downstream of the dampening fluid supply chamber in fluid communication with the dampening fluid supply chamber, the dampening fluid supply channel delivering dampening fluid onto a reimageable surface of an imaging member; an air and vapor mixing conduit positioned upstream of the dampening fluid supply chamber in fluid communication with the dampening fluid supply chamber, the air and vapor mixing conduit having an air inlet for generating a flow of air on an interior of the air and vapor conduit; and a dampening fluid vapor mixing chamber, the dampening fluid vapor mixing chamber arranged around an entire circumferential surface of a section of the air and vapor mixing conduit at a position downstream of the air inlet and upstream of the dampening fluid supply chamber, the dampening fluid vapor mixing chamber having a plurality of dampening fluid vapor inlets, and a plurality of vapor exit ports that are aligned with openings in the air and vapor mixing conduit that connect with an interior of the air and vapor mixing conduit, the dampening fluid vapor entering the dampening fluid vapor mixing chamber via the plurality of dampening fluid vapor inlets and exiting the dampening fluid vapor mixing chamber through the plurality of vapor exit ports directing the dampening fluid vapor toward an axial center of the air and vapor mixing conduit to entrain the dampening fluid vapor in the generated flow of air.
