なる。2. Description of the Related Art Generally, a lubricating oil mist supply system supplies oil mist generated by an atomizing device at one location to each lubricating location through a pipe. When conducting or interrupting the control of the supply flow path, it is preferable that the flow path of oil mist gas or the like be a linear flow. This is because if the flow path is refracted, the oil mist is combined with each other at the refraction portion, and the oil mist is enlarged and settles before reaching the lubrication portion and adheres to the wall surface of the pipe. On the other hand, in recent years, with the increase in speed, precision and multifunction of processing machines, the temperature rise of the lubricated part is suppressed and the distortion of the machine caused by heat is made minute so that the oil content in the oil mist air is reduced, As the air content increases, the oil mist air pressure also tends to increase. Therefore, the amount of air consumed is also increasing. Therefore, it is necessary to eliminate unnecessary air consumption in terms of equipment for generating compressed air or energy saving. Particularly in a multifunctional machine, one of the lubricated parts is in a driven state according to the processing target of the machine. At this time, the oil mist air supply to the lubrication target part in the idle state is not only a waste of air consumption, but also the lubricating oil is excessively supplied. This will cause the temperature of the parts to rise. In addition, the excess oil accumulated in the meantime is pushed out by the air pressure of the oil mist and is scattered, impairing the cleanliness around the machine.

In the figure, an auxiliary air circuit including a flow rate adjusting valve bypassing the atomizing device 8 is shown, but this is for explanation. In general, it is integrally incorporated in the atomizing device 8 under the name of an air bypass adjusting valve or the like. FIG. 10 is a configuration diagram of the main part thereof. Further, FIG. 11 is a longitudinal sectional view showing an example of a conventional two-way valve used for this. In this lubricating oil mist supply system, the oil mist generated by the atomizer 8 is supplied to the plurality of two-way valves 5 via the flow path 6. Two-way valve 5
Is selectively turned on / off by a control signal to supply oil mist to an arbitrary lubricated portion 13.

正な所定圧力で潤滑油霧を供給することが困難である。In the above-described conventional lubricating oil mist supply system and valve device, as shown in FIG. 11, the fluid entering from the inlet 1 is complicatedly refracted inside and then the outlet 3 is discharged.
Come out of. Therefore, the oil mists have a drawback that they are combined with each other and become enlarged and settle. Also,
There is a ball valve as a desirable valve without bending of this flow path, but when trying to operate the ball valve remotely,
There is a drawback that the device becomes complicated and the shape becomes large, such as a combination of a cylinder or a rack and a pinion. Further, as shown in FIG. 10, when connecting a plurality of two-way valves, it is necessary to connect the flow path 6 and an elbow, a T-joint, etc., which not only requires extra parts but also reduces the piping cost. And requires a large installation space,
The piping work was complicated. Further, as shown in FIG. 9, only the opening of the air passage is adjusted by the flow rate adjusting valve 8a used when increasing the air content in the oil mist air, and the pressure is replenished or the excess pressure is relieved by an air pressure like a pressure reducing valve. Since it does not have a maintenance function of the above, the pressure in the flow path 6 rises and falls depending on the number of open / closed states of the two-way valve 5. That is, it is difficult to always supply the lubricating oil mist to the lubricated portion at an appropriate predetermined pressure.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lubricating oil mist supply system and a valve device that can always supply a lubricating oil mist to a lubricated portion at a constant pressure even if the two-way valve unit is selectively driven by an arbitrary combination and number.

Since the required amount is selectively supplied only to the parts that need lubrication at the required time, oil mist air is not supplied to the lubricated part 13 that is not in operation, and the temperature of the bearing part rises due to excessive oil supply. It is also possible to prevent contamination around the machine due to excess oil scattering. Further, since the passage of the fluid is not bent, it is possible to prevent the oil mist from enlarging. Further, it is possible to prevent wasteful oil mist and air consumption. Further, since the air supplied to the oil mist for increasing the air amount is supplied through the pressure reducing valve function device, the pressure can be maintained at the set desired value, so it is easy to determine how many valve units are closed. Even in such a case, oil mist air having a predetermined pressure can always be supplied to the lubricated portion from the valve unit in the open state.

に合わせて自在に行える。Further, the branching process for the return air is performed for each two-way valve unit and the air communication passage is not set, so that the processing cost and extra piping can be reduced. Furthermore, since the valve body 25 can be easily replaced by simply removing the lid 31, the mode of the valve body 25 can be changed with the valve device assembled. That is, as shown in FIG. 7, the hole 25a of the valve body 25 comes to the position of the outlet 26 when the valve body 25 is driven, or as shown in FIG.
According to the convenience of the signal transmitting section, it is possible to freely select whether to open or close when the air is driven, depending on whether the outlet 26 is located when the vehicle is not driven.
