Patent ID: 8016651

Claim:
A vehicle HVAC module assembly for aspirating air from an interior vehicle passenger compartment of a vehicle, the vehicle HVAC module assembly comprising: a first HVAC module housing section including a first coupling surface, the first HVAC module housing section further including a first portion formed about the first coupling surface; and a second HVAC module housing section including a second coupling surface, the second HVAC housing section module further including a second portion formed about the second coupling surface, the second portion is in fluid communication with the interior vehicle passenger compartment of the vehicle, the first and second HVAC module housing sections forming a HVAC mixing chamber within the vehicle by a coupling of the first and second coupling surfaces wherein the first coupling surface is seated against the second coupling surface, the HVAC mixing chamber mixing forced air and conditioned air therein, and wherein the first coupling surface at the first portion mates with the second coupling surface at the second portion to cooperatively form a vacuum chamber that draws air from the interior vehicle passenger compartment in response to the conditioned and forced air from the HVAC mixing chamber flowing through the vacuum chamber.
