４ｂが吸着口８側の貫通路５ｂを閉塞する状態になる。Next, an example of use of this valve unit will be described. First, a suction pad formed of an elastic body is connected to the suction port 8 so that the suction target 8 can be easily sucked, and then the suction target 8 is brought into contact with the suction pad 8. When sucked by the blower from the suction port 9 of this valve unit, the air in the through passage 5 formed in the cylindrical body 20 is sucked and exhausted, and the adsorbed substance is sucked. At this time, in the valve unit of the portion closed by the object to be adsorbed, the valve body 4 is temporarily sucked upward due to the suction force of the blower, but the air in the valve body chamber 3 is also sucked and becomes the same pressure state. As a result, the valve body 4b falls by its own weight and the valve body 4b closes the through passage 5b on the suction port 8 side.

吸着口８より吸引は行われない。On the other hand, when the suction port 8 is not blocked by the object to be adsorbed, air is sucked from the suction port 8 and the valve body 4 is sucked upward by the flow of this air, and the suction port 9
The through passage 5a on the side is closed, and the through passage 5a is completely airtight by the valve body 4a. Therefore, in this valve unit 8, the valve body 4a sucked upward does not move downward unless the suction of the blower is stopped,
No suction is performed from the suction port 8.
