Abstract: This invention relates in general to a fluid device and to a method of changing the aperture size of an orifice aperture. The invention relates in particular to a technique capable of easily forming an orifice aperture having an exact aperture size and easily making a change in the orifice aperture size. While being brought into communication with a connecting pipe 83 through an intersecting inner aperture 633 drilled in a lower plate 63 of a device main body 6, two inner apertures 632, 632 with their one ends opening to a recessed portion 631 are each provided with a female thread 634. An orifice member 4 provide with a through-hole 412 having a corresponding inside diameter to an orifice aperture and communicating with a hexagon socket into which a hexagon bar spanner wrench 16 is internally fit, is threaded into each female thread 634, whereby the orifice member 4 is mounted. Finally, a covering member 15 is sealingly threaded into an opening of the other end of each inner aperture. Air supplied from the connecting pipe passes through the through-hole 412 serving as the orifice aperture and is blown into oil stored within the recessed portion from an end opening 413. If replacement orifice members with respective through-holes having different inside diameters are prepared, this makes it possible to make a change in the orifice aperture size by replacing the existing orifice member with a replacement orifice member.

Abstract: A piping device of the present invention includes an oil supply path, a narrower path connected with the oil supply path and having an inside diameter smaller than that of the oil supply path, an air space into which the oil is discharged from the narrower path, a wall defining the air space having a recess, and a plurality of branch paths into which the oil having impinged on the recess flows, wherein a vertex of the recess and an end of the narrower path face each other. This configuration makes it possible to suppress the uneven distribution of a flow rate of oil discharged into the air space. Furthermore, since the vertex of the recess and the end of the narrower path face each other, the discharged flow in which the uneven distribution of the oil flow rate is suppressed can be diverted with respect to the vertex of the recess as the center of the diversion. Thus, it is possible to allow flow rates of oil flowing into the respective branch paths to be substantially uniform with a simple configuration. As a result, it is possible to provide a piping device capable of stabilizing the relationship among flow rates of oil discharged from outlets even with use of a simple configuration, and to provide a cutting oil coater employing the same.
