Abstract
An exhaust fumes distribution system for use within a structure adjacent to a space in which a vehicle having an engine coupled to a vertically oriented, open ended, exhaust stack is to be located to discharge exhaust fumes out of the structure. The system comprises an blower, an elongated, hollow guide tube having a slot extending the length thereof. The guide tube includes a pair of sealing members located along the slot for forming a sealed interface through which the exhaust stack is arranged to enter, so that fumes from the stack are carried down the guide tube and vented out of the structure by the blower. The sealing members are of generally C-shape in cross section so that peripheral portions thereof abut along the length of the slot to form the sealed interface. The interface is arranged to open at any point along the length thereof for receipt of the open end of the exhaust stack of the vehicle, with the remaining portions of the interface remaining sealed so that the exhaust fumes cannot gain ingress into the interior of the structure through the interface.
