Description

  The present invention relates to an intake / exhaust integrated device in which a fluid blowing nozzle that ejects a pressure fluid and a fluid suction nozzle that sucks a fluid are combined.

2. Description of the Related Art Conventionally, as a fluid blowing nozzle that ejects a pressure fluid, for example, an underwater nozzle for increasing efficiency and efficiency is known in an underwater cleaning operation.
In the above-described known technique, an air pipe communicating with the atmosphere is connected to a diffuser that surrounds a nozzle to eject a high-pressure liquid in water and opens in a direction of ejecting the liquid from the nozzle, thereby ejecting the liquid from the nozzle. The underwater nozzle is configured such that air is sucked into the diffuser through the air pipe by the generation of negative pressure due to the above, and the liquid is ejected into the water together with the bubbles (see Patent Document 1).
However, in the submerged nozzle, the positional relationship between the nozzle and the diffuser is fixed, the nozzle cannot be moved back and forth in the axial direction, and the nozzle cannot be replaced.
For this reason, the speed of the ejected fluid cannot be adjusted, and the nozzle can not be freely replaced according to various applications.
Therefore, the present inventor invented a fluid acceleration stabilizing device that can adjust the speed of the ejected fluid by moving the nozzle back and forth in the axial direction, and can replace the nozzle according to various applications. Filed as -293370.
