ーマイクロバルブ装置。[Scope of claim for utility model registration] 1. A valve chamber communicating with the primary port inside the case,
a disc-shaped valve body having an outer diameter slightly smaller than the inner diameter of the valve chamber and movable up and down within the valve chamber with a small ring-shaped gap with respect to the inner wall of the valve chamber; and an operation chamber that communicates with the secondary port, and an insertion hole for a hollow cylinder in the center, the lower end of which is located within the operation chamber and forms a floating gap with the valve body for operation with the secondary port. an airtightness maintaining member that communicates with the chamber; and a spring member that is movable up and down in the insertion hole and has an operating portion and an opening communicating with outside air at the top, and is provided between the airtightness maintaining member. and a hollow cylindrical body that is always elastically biased upward by the airtightness retaining member. The lower end receives and restricts the upward movement of the valve body to block the flow of the primary air to the secondary port side, and the air gap is formed between the valve body and the airtightness maintaining member. On the other hand, when the operating section is pressed down against the spring member, the lower end of the hollow cylindrical body abuts the valve body within the operating chamber and moves it downward, causing the operation chamber and While the secondary port is communicated, the primary air introduced from the primary port is allowed to flow into the operation chamber and the secondary port side through a small gap between the valve chamber wall and the valve body, and the spring is returned to its elastic state. This is an air microvalve device in which the operation chamber is opened to a secondary port and the outside air by forming the above-mentioned floating gap. 2 Utility model registration claim 1, in which a sealing material such as a packing or an O-ring is installed between the airtightness maintaining member, the hollow cylinder, the airtightness maintaining member, and the case wall surface in contact with the airtightness maintaining member. The air micro valve device described. 3. The air micro-valve device according to claim 1, wherein the air gap between the upper surface of the disc-shaped valve body and the airtightness maintaining member is used to vent residual air on the secondary port side. 4. Utility model registration claim 1, characterized in that the valve chamber is slightly larger than the thickness of the disc-shaped valve body, and a floating gap is formed between the bottom surface of the valve chamber and the lower surface of the valve chamber. The air micro valve device described. 5. The air micro-valve device according to claim 1, wherein the disc-shaped valve body has a plurality of notches serving as air passages around a circular circumference. 6. The air micro-valve device according to claim 1 or 3, or 4 or 5, wherein the disc-shaped valve body is an elastic body such as urethane resin or hard rubber.
