- the multi-way valve for example, three-way valve
- the multi-way valve for example, three-way valve
- the switching valve 67 is preferably disposed not in the branch portion 61 but in the return flow path 64.
- the switching valve 67 is disposed in the return flow path 64, there is no possibility that the trapped air may flow to the mixing valve 2 side, even if the air is trapped in the switching valve 67 itself, or the possibility Is low.
- the switching valve 67 may be omitted.
- a device e.g., a clip or the like
- the air removal device 1 may be used to open and close the return flow path 64.
- the upstream end 64 a of the return flow path 64 is positioned above the upstream end 52 a of the second supply flow path 52 in the branching portion 61 in a state where the air vent 1 is operably installed. ing. For this reason, even if air is mixed into the first supply flow channel 51, the mixed air moves to the return flow channel 64 positioned above in the branch portion 61. Thus, the mixed air does not reach the mixing valve 2 through the second supply flow path 52.
- the downstream end portion 64 b of the return flow path 64 is connected to the lubricating oil tank 4. For this reason, the air mixed in the first supply passage 51 is sent into the lubricating oil tank 4 through the return passage 64. Thus, air is removed from the first supply flow path 51 (and the circulation flow path CF).
- the removal of the air is performed, for example, by driving the lubricating oil supply pump 71 in a state in which the return flow path 64 is opened (for example, a state in which the closing of the return flow path 64 by the switching valve 67 is released). Be done.
- the pressure in the second supply flow path 52 is the operating pressure of the mixing valve 2 (more specifically, the metering discharge valve 23 Does not exceed the operating pressure of Therefore, even if the lubricating oil supply pump 71 is driven, the mixing valve 2 prohibits the movement of the lubricating oil A, so that the lubricating oil A mixed with air moves in the second supply flow passage 52 Absent.
- the mixing valve 2 itself functions as a closed valve during the removal operation of the mixed air mixed in the first supply flow channel 51. For this reason, during the removal operation of the mixed air, the lubricating oil A mixed with the air is reliably prevented from moving from the branch portion 61 to the second supply flow path 52 side.
- the operator may release the closing of the return flow path 64 and then drive the lubricating oil supply pump 71 in the operation of removing the mixed air. Further, in the example shown in FIG. 1, the lubricating oil A returns to the lubricating oil tank 4 without being discharged to the outside of the air removing device 1 during the operation for removing the mixed air. Therefore, the lubricating oil A is not wasted, and the lubricating oil A does not contaminate the surroundings of the air vent 1 and the mixing valve 2.
- the upstream end 64 a of the return flow path 64 is connected to the upper portion of the branch portion 61, and the upstream end 641 of the return flow path 64 extends upward from the branch portion 61. It extends. Therefore, in the example shown in FIG. 1, the upstream end 641 of the return flow path 64 functions as a buffer space for receiving air. For example, it is assumed that the operation of removing the mixed air is insufficient and the air still remains in the first supply flow passage 51. In this case, when the return flow path 64 is closed and the lubricating oil supply pump 71 is driven, the lubricating oil A flows in the first supply flow path 51 and the second supply flow path 52.
- the air (a part of the air or the whole air) entering the branch portion 61 rises in the branch portion 61 and is held at the upstream end 641 (buffer space) of the return flow path 64. For this reason, even if the operation of removing the mixed air is insufficient, the entry of the mixed air to the mixing valve 2 side is suppressed.
- a machine tool is a large structure fixedly installed in a factory, and can not easily change the position of the machine tool main body in daily inspection or regular maintenance. For this reason, the operator needs to remove the maintenance cover and the like of the fixedly installed machine tool and approach the location where the maintenance should be performed.
- mixing valves that supply lubricating oil to the lubrication part of the machine tool are often arranged in the machine tool or at the top of the machine tool. Therefore, the operation of operating the mixing valve and removing the air mixed in the lubricating oil supply flow path is the operation in the machine tool or on the machine tool. For this reason, the air removing operation using the mixing valve has a large work burden on the worker from the viewpoint of the work environment.
- the first embodiment it is possible to remove the mixed air before the air mixed in the lubricating oil supply channel reaches the mixing valve through the lubricating oil supply channel.
- the mixing of air into the mixing valve is suppressed, the operation of removing the air from the mixing valve becomes unnecessary or the frequency of the operation is reduced. Therefore, when the air venting apparatus according to the first embodiment is used, the burden on the operator who performs maintenance of the machine tool is greatly reduced.

Therefore, if the operation for removing the mixed air is performed after replacing the foreign substance removal filter 74 (that is, if the lubricating oil supply pump 71 is driven with the return flow path 64 opened), the mixed air is 1 removed from the supply flow path 51
- a first foreign matter removal filter 74 a (that is, a line filter) is provided in the middle of the first supply flow channel 51 (that is, in the middle portion).

- the second foreign matter removal filter 74 b prevents foreign matter in the lubricating oil tank 4 from entering the first supply flow passage 51.
- the second foreign matter removal filter 74 b is disposed inside the lubricating oil tank 4, and therefore, is difficult to replace as compared with the first foreign matter removal filter 74 a. Therefore, the second foreign matter removal filter 74b may not be replaced for a long time. In this case, there is a possibility that a part of the surface layer of the second foreign matter removing filter 74b may be separated to be a foreign matter.
- the second foreign substance removal filter 74b is a filter that hardly part of the surface layer peels off (for example, wire mesh type (Filter of The second foreign matter removal filter 74b may be rougher than the first foreign matter removal filter 74a. In this case, it is possible to prevent clogging of the first foreign matter removal filter 74a and reduce the frequency of replacement by removing relatively large foreign matter with the second foreign matter removal filter 74b.
- one of the first foreign matter removing filter 74a and the second foreign matter removing filter 74b may be omitted.
