Otherwise, this work would have to be done manually by the worker, which was an obstacle to automating the work equipment. Furthermore, if such a fluid return method is adopted, it is possible to return almost the entire amount of working fluid in the main flow path to the tank side, but generally there is a member in the discharge section, such as a nozzle, whose flow path becomes narrower toward the tip. Because of this, the return efficiency is poor, and components and solids that are easy to solidify remain in the blind area when viewed from the tip side of the flow path.
This may cause problems in subsequent use.

The object of the present invention is to obtain a method for returning fluid in which working fluid components and the like are unlikely to remain in the discharge portion.

The connection part of this auxiliary pipe is an intermediate part between the tank and the discharge part. In the operation of returning the working fluid, the processing fluid is supplied from the auxiliary pipe to the main pipe, the working fluid from the tank side is returned to the tank from the auxiliary pipe connection part, and the fluid is discharged from the discharge part to the other side. Now, considering the fluid that returns to the tank side, since neither the processing fluid nor the working fluid passes through the discharge section, fluid resistance is relatively small, making it possible to proceed with the work efficiently. Furthermore, since the fluid flows in the forward direction in the discharge section, dead water areas are less likely to occur in the flow path, and the problem of solid matter remaining in the vicinity of the discharge section can also be avoided. Furthermore, since there is no need to connect a flow path to the tip side of the discharge part, for example, by combining an appropriate valve mechanism and control mechanism, it is possible to obtain a working device that can automatically perform discharge and return operations. .
