PURPOSE:To freely perform deflection by arranging a nozzle, with a round hole, at an entrance part and also arranging a guide wall, of gradually expanding shape, at an exit part and making the nozzle movable within the nozzle surface so as to control a condition of attachment of a flow, which rises from the nozzle, to the guide wall. CONSTITUTION:A controller 1 for the direction of a flow is formed by an entrance part main body 2 and an exit part main body 3. Said main body 3 has a guide wall 4 with a section of flow passage gradually expandiug towards the downstream, while said main body 2 has a lever support part 8, nozzle support part 9 and a nozzle spacer 10. A nozzle movement lever 16, held in swiveling configuration by means of a support part 18, is inserted in an opening 21 for a lever holding member 20. A nozzle 11 can be set in an optional position in a circle formed at the upstream end 5 of the guide wall due to movement of the lever 16. Thus, deflection of flow is perfomed with small airflow through utilizing change of the backpressure in the upstream side with movement of the nozzle and also attachment of the flow to the guide wall. |
