PURPOSE:To prevent accumulation of articles to be transported at an intermediate pressurized portion by disposing in a lateral alignment suction ports longitudinally short and having a bore diameter large enough to suck the whole amount of fluid in a main pipe and providing a nozzle-shaped discharge pipe for discharging sucked fluid under pressure in the inside of the main pipe where the suction flow and the discharge flow contact each other. CONSTITUTION:In case of using only the inside of a pipe, a flow path is composed of suction pipes 1, a discharge pipe 2, suction flows 1', a discharge flow 2', suction ports 1'', a discharge port 2'', a contact plane P between the suction and discharge flows, and articles 4 to be transported, and the articles 4 carried by the suction flow 1' break the wall P and immediately flow down in the discharge flow 2. Thus, articles carried by the suction fluid can easily break the wall P individually and independently and then flow in the discharge flow, and as the flow rate and speed are equal before and after the wall P, articles are not accumulated.
