Abstract
A pipe conduit vehicle having a substantially cylindrical housing and with at least one ring-shaped sealing element disposed between the outer side of the housing and the inner wall of the pipe conduit can be moved in the pipe conduit via the transport fluid flow. The pipe conduit vehicle thereby comprises at least one inlet opening and at least one outlet opening which form a bypass through the inner portion of the housing to reduce the pressure differential before and after the pipe conduit vehicle, wherein the at least one inlet opening is disposed on the outer surface of the cylindrical housing.
