CLASS 180, MOTOR VEHICLES |
164 | WITH POWERED MEANS FOR CREATING FLUID FORCE TO ATTRACT VEHICLE TO SURFACE OF TRAVEL: |
This subclass is indented under the class definition. Vehicle provided with a fluid-moving device (e.g., blower, fan) driven
by the vehicle’s propulsion motor or by an auxiliary motor, for
causing a flow of fluid (ordinarily air) away
from all or a portion of the region between the vehicle and a surface
on or along which it may travel (usually a vehicle-underlying
surface) and with such confining structure (e.g., apron, seal) for
the region as may be necessary to cause the flow of fluid therefrom
to result in a less-than-ambient pressure in the region, thus
causing the vehicle to be attracted to the surface (by
a force greater than that of gravity when the surface is a vehicle-underlying
one).
