In this spray nozzle, pressurized fluid is introduced into a cylindrical vortex chamber with tangential force, creating a high-speed vortex motion, so that when discharged from the discharge orifice due to centrifugal force, the fluid sprays in the form of a hollow cone. becomes.

ことができず且スプレーノズルの有効なスプレー効果を
充分に達成することもできなかった。In this type of spray nozzle, a long air core that reaches the bottom wall of the vortex chamber is created in the spray nozzle due to the vortex motion of the fluid, but the end of this air core or the vortex motion itself causes large wear on the nozzle body. In such cases, there was a risk that a hole would form in the bottom of the nozzle body in a short period of time. Therefore, in order to minimize the wear caused by the air core in this type of spray nozzle, a vortex chamber with a crude configuration has been proposed. It was not possible to easily manufacture a spray nozzle using this technology, and it was also not possible to fully achieve the effective spray effect of the spray nozzle.

摩耗を生ずる欠点があり、実用性に乏しかった。On the other hand, in addition to preventing wear on the spray nozzle, in order to achieve a uniform t n+ when spraying, for example, in the form of a hollow cone, the inlet and vortex chambers should be aligned so that the air core is aligned with the central axis of the discharge orifice. It is necessary to configure it appropriately. When fluid is introduced tangentially into the vortex chamber, unbalanced forces tend to occur, and there is a risk that the air core, especially the lower part, may be displaced from the axis of the discharge orifice within the vortex chamber, resulting in non-uniform spraying. Further, even if the flow direction of the fluid changes slightly in the inflow section or the bottom wall of the vortex chamber, the position of the air core becomes unstable, resulting in non-uniform spray. Various configurations have been adopted to align the air core with the central axis in the vortex chamber, but as mentioned above, some of them are difficult to manufacture and expensive, and the discharge volume h4 cannot be easily changed. It still has the drawback of causing excessive wear, and is therefore impractical.

）。In the present invention, a vortex chamber column is provided in the nozzle body, and the vortex chamber column extends in the axial direction upward from the bottom of the vortex chamber, and preferably guides the fluid introduced into the vortex chamber in the tangential direction. It functions as follows. There are four grooves at the upper end of the vortex chamber column, which allow the air core position of the vortex flow to be formed on the center axis of the vortex chamber, and also to prevent the vortex chamber column from forming a hole due to the generation of the air core. Wear can be minimized. Further, in detail according to the embodiment shown in the drawings, the nozzle body Qυ has an upright column (c) forming a vortex chamber column.
As shown in FIG. 14) upper surface (1
4&), it projects perpendicularly to the bottom wall α3 of the vortex chamber. Moreover, the upright column (to) has a vortex chamber (12).
The actual inflow channel 041 has a diameter of about one-half of
has a diameter slightly less than half the diameter of the vortex chamber (12). In this case, the diameter of the inflow channel θ barrel may be expanded to one half of the vortex chamber. As a result, the pressure fluid introduced into the vortex chamber 0 through the inflow path 04 flows around the upright column (A). In other words, the upright column (support) guides the fluid flow appropriately. (See Figure 3).

The recess may function to align the air core formed in the vortex fluid with the central axis of the vortex chamber (1) and may serve to enhance the uniformity of the emitted spray. By providing this, the nozzle body (the wear of the upright column (A) caused by the air core generated in IINC can be suppressed to a minimum. Concentric outer peripheral end (29a)
is formed. Even when the recess is formed into another shape, it is preferable that the recess is provided with a continuously curved outer peripheral end (29a), and this outer peripheral end part can prevent the destruction of the vortex flow. The generation of turbulent flow is prevented, and the air core can be smoothly formed with the bottom portion (25a) as the end.

This spray nozzle can be applied to a variety of spray nozzles with different capacities without compromising the wear resistance of the upright column or the uniform spray action from the discharge orifice. That is, if the characteristic configuration according to the present invention is provided without changing the configuration of the spray nozzle described above, the inflow path (I4
