Class Information
Number: 180/302
Name: Motor vehicles > Power > Including traction motor of kind driven by expansible fluid from source external of motor
Description: Vehicle wherein the apparatus for producing power includes a motor of a type operated by a fluid, which is undergoing an increase in volume as the result of having been subjected to an elevation of its pressure or temperature at a location outside the motor, for imparting vehicle-propelling movement to one or more surface-engaging members of the vehicle.
