目的は、潤滑のため以外に冷却でもある。(Prior Art) As shown in FIG. 3, this type of conventional spray lubrication device sends compressed air to a bench-lily oil mist generator 2 through an air supply path 1, and applies negative pressure according to the supplied air pressure. The negative pressure is used to suck up the oil 3 to form oil mist, and the oil mist is distributed through the main oil supply path 4 and branch oil supply paths 5A to 5E to lubricate locations such as ball bearings or roller bearings. 5A, a lubrication point 6B such as a plain bearing, a lubrication point 6C such as a gear, a lubrication point 6D such as a chain, and a lubrication point 6E such as a slide member for lubrication. In this case, the purpose of supplying oil mist with compressed air to each lubricating point is not only for lubrication but also for cooling.

た。(Problem to be solved by the invention) However, in the conventional spray lubrication system, compressed air is sent to the bench lily type oil mist generator 2 at the same pressure even when it is necessary to increase or decrease the number of lubrication points over time. Therefore, since the amount of compressed air and the amount of oil mist contained in this compressed air are constant, if the number of lubrication points increases, not only will the injection pressure of oil mist decrease and a sufficient amount of oil mist will not be supplied. However, there was a problem that the cooling effect was also reduced. Additionally, when the number of lubrication points decreases, the amount of compressed air and oil mist increases relatively, resulting in excessive oil mist at the lubrication points.
Furthermore, the flow rate of the oil mist increases, and if the flow rate is too fast, the oil mist will be separated from the air by centrifugal force at the bend in the oil supply path and will adhere to the inner surface of the oil supply path, making it impossible to supply sufficient oil. There was a problem with it disappearing.

In a spray lubrication device that supplies oil mist to a plurality of lubrication points via oil supply passages, each of the branch oil supply passages is provided with a selection valve for selecting whether or not to supply oil mist, and a selection valve is provided in the middle of the air supply passage.

The inside of the control chamber 17 is divided into a feedback chamber 19 and a pilot chamber 20 by a partition membrane 18 such as a diaphragm. Atmospheric pressure acts within the pilot chamber 20 through a communication hole 21. Partition membrane 18
A pilot valve seat 22 is provided in the center, and a pilot valve hole 23 extending across the pilot valve seat allows the feedback chamber 19 and the pilot chamber 20 to communicate with each other.

縮空気の圧力は変化しなくなる。 In such an oil mist lubrication device, a valve opening signal is output from a valve operator (not shown), and, for example, the selection valves 7A, 7 are activated.
If B and 7C are opened, the pressure on the outlet side of the oil mist generator 2 will drop below the set pressure. This pressure is transmitted to the feedback chamber 19 of the feedback type pressure reducing valve 9 via the feedback path 8. Since the set pressure is applied to the partition membrane 18 by the pressure setting tool 26, when the pressure in the feedback chamber 19 falls below the set pressure, the pilot valve seat 2 and the partition membrane 18
2 is pushed out toward the feedback chamber 19, thereby pushing the valve body 14 through the valve stem 15 and separating it from the valve seat 12. Therefore, the amount of compressed air passing through the passage 11 increases, and the pressure on the outlet side of the oil mist generator 2 also increases. When the pressure on the outlet side of the oil mist generator 2 reaches the set pressure, the pressure in the feedback chamber 19 and the set pressure of the pressure setting tool 26 are balanced, and the partition membrane 1
8 becomes neutral. Therefore, even if the number of openings of the selection valve changes, the pressure of the compressed air containing oil mist applied to each lubricating location does not change.
