- the seal ring 19 is a square ring having a quadrangular cross section, is fitted and mounted on the outside of the cylinder body 13A, and its base end side surface is in contact with the flange portion 13B.
- the outer diameter of the seal ring 19 is slightly smaller than the outer diameter of the flange portion 13B, and the axial length of the seal ring 19 is the same as that of the cylinder body 13A. It is longer than the length of the tip side portion of the flange portion 13B.
- the flange portion 13B of the tubular portion 13 projects laterally from the seal ring 19, and the seal ring 19 projects toward the tip side in the insertion direction from the tip opening of the tubular portion 13.
- the plate portion 15 has a vertically long plate shape protruding from the proximal end surface of the tubular portion 13 (including the proximal end side surface of the flange portion 13B) toward the proximal end side, and is formed in the plate thickness direction. It has a pair of flat tool contact surfaces 16 that line up.

It is flush with the end face.
- the tool contact surface 16 of the plate portion 15 and the base end surface of the cylinder portion 13 are chamfered by R.
- a shaft receiving hole 17 is formed through the plate portion 15 on an extension line of the central hole 13K of the tubular portion 13.
- the shaft receiving hole 17 is flush with the central hole of the tubular portion 13 on the tip side of the plate portion 15, while the inner diameter of the shaft receiving hole 17 is larger than that of the central hole 13K of the tubular portion 13 on the base end side of the plate portion 15. Is getting smaller.

It is inserted into the shaft body 21 in a compressed state between the two. Due to the elastic force of the compression coil spring 30, the valve body 25 comes into contact with the seal ring 19 and is urged to close the core mounting hole 52 (see FIG. 1) with respect to the internal space of the tire (not shown). ing.
- the plate portion 15 is about 3 to 5 times as large as the tubular portion 13. That is, in the axial direction, the plate portion occupies about 3/4 to 5/6 of the support base 12. Then, the entire male screw portion 12N screwed with the female screw portion 57 of the core mounting hole 52 (see FIG. 1) is formed at the base end portion of the plate portion 15. Further, as shown in FIG. 6, the valley portion 12N1 of the male screw portion 12N is flush with the end surface of the flange portion 13B in the tubular portion 13. Further, in the male screw portion 12N, the width of the valley portion 12N1 is larger than the width of the mountain portion 12N2 in the axial direction.
- an orthogonal hole 18 orthogonal to the shaft receiving hole 17 and having an opening in the pair of tool contact surfaces 16 is formed through the plate portion 15.
- the cross-sectional shape of the orthogonal hole 18 is a vertically long oval shape extending from the position near the base end surface of the tubular portion 13 to the position near the base end side surface 15A of the plate portion 15.
- the orthogonal hole 18 communicates with the shaft receiving hole 17.
- the support base 12 is made by cutting a metal cylinder as follows. That is, for example, a first central hole having a circular cross section is formed from the tip of the cylinder to a position near the base end, and a second central hole having an inner diameter smaller than that of the first center hole is formed in the remaining portion.
- the male screw portion 12N is formed at the base end portion in the axial direction on the outer peripheral surface of the cylinder
- the second portion in the radial direction is formed in the portion of the cylinder about 3/4 to 5/6 from the base end portion.
- Both sides of the central hole are cut off to form a plate portion 15.
- an orthogonal hole 18 is formed through the plate portion 15 so as to be orthogonal to the first and second central holes.
- the tip portion of the portion that is not the plate portion 15 is cut so that the outer diameter is reduced in a stepped manner to form the tubular portion 13 having the flange portion 13B.
- valve core 10 of this embodiment is as described above. Next, the action and effect of the valve core 10 will be described.
- To fix the valve core 10 in the core mounting hole 52 insert the valve core 10 into the core mounting hole 52 from the tubular portion 13 side, and insert the female screw portion 57 of the core mounting hole 52 and the male screw portion 12N of the valve core 10.
- the valve core 10 can be screwed to the back by applying the tool 100 having a slit in the center to the tool contact surface 16 of the plate portion 15.
- the valve core 10 By deepening the screwing between the male and female screw portions 57 and 12N, the valve core 10 is propelled to the inner side of the core mounting hole 52, and the seal ring 19 enters the tapered portion 56 and comes into close contact with the core body. 11 and the inner surface of the core mounting hole 52 are sealed. Then, when the flange portion 13B abuts on the tapered portion 56, the mounting of the valve core 10 on the core mounting hole 52 is completed. Even if the seal ring 19 receives a force in the axial direction due to friction with the tapered portion 56, the seal ring 19 abuts on the front end side surface of the flange portion 13B, and the positional deviation in the axial direction is prevented.
- the valve core 10 is always in a closed state in which the valve body 25 of the movable shaft 20 is addressed to the seal ring 19 of the core body 11 by the elastic force of the compression coil spring 30.
- a charge pump is connected to the charge port 53 of the valve stem 50, and compressed air is sent into the core mounting hole 52.
- the movable shaft 20 moves linearly against the compressed coil spring 30 due to the pressure of the charged compressed air, a gap is created between the valve body 25 and the seal ring 19, and the charging port is formed. Compressed air flows from the 53 side to the back side of the core mounting hole 52.
- the movable shaft 20 moves to the charge port 53 side due to the elastic force of the compression coil spring 30 or the elastic force and the pressure on the back side of the core mounting hole 52, and the valve body. 25 returns to the state where the seal ring 19 of the core main body 11 is closed. At this time, even if the central axis of the core body 11 and the central axis of the movable shaft 20 are slightly deviated, the inclined surface 22B of the protruding portion 22 of the movable shaft 20 hits the tip opening edge of the seal ring 19 or the support base 12. You will be guided in contact.
- the entire male screw portion 12N is formed on the plate portion 15 of the support base 12 of the core main body 11. That is, the shape is such that the outside of the tool contact surface 16 is cut out up to the tip end of the male screw portion 12N or to the tip side of the tip end, so that it is male like a conventional valve core. It is possible to reduce the weight as compared with the configuration in which only the middle part of the screw portion is cut out. Moreover, in the axial direction, the plate portion 15 occupies more than half of the support base 12 (about 3/4 to 5/6 in this embodiment), that is, more than half of the support base (3 in this embodiment). Since the outside of the tool contact surface 16 is notched in (4/4 to 5/6), the weight can be further reduced. Further, in the present embodiment, in the male screw portion 12N, the valley portion 12N1 is wider than the mountain portion 12N2, so that the weight can be further reduced.
- the surface of the flange portion 13B opposite to the seal ring 19 forms the base end surface of the tubular portion 13 and is orthogonal to the pair of tool contact surfaces 16, more is cut out. It will be lighter. Further, since the support base 12 is formed with orthogonal holes 18 having openings in the pair of tool contact surfaces 16, the weight can be further reduced. Moreover, since the orthogonal hole 18 communicates with the central hole 13K and the shaft receiving hole 17 of the tubular portion 13, the fluid passing through the central hole 13K and the shaft receiving hole 17 of the tubular portion 13 passes through the orthogonal hole 18 at the time of opening the valve. Also flows to the outside of the core body 11, so that the fluid flow at the time of valve opening can be smoothed. Further, since the orthogonal hole 18 has an oval shape that is long in the longitudinal direction (longitudinal direction) of the plate portion 15, the cross-sectional area of the orthogonal hole 18 becomes large, and further weight reduction can be achieved.
- valve body 25 is configured to be assembled to the shaft body 21 which is a separate component, for example, the valve body is integrally formed with the shaft body by carving out a cylindrical member.
- the movable shaft 20 can be easily manufactured.
- seal ring 19 and the flange portion 13B are in surface contact with each other, the positioning of the seal ring 19 is stable.
- FIG. 9 to 11 show the valve core 10W of the second embodiment.
- the front end side surface (the surface on the seal ring 19 side) is orthogonal to the base end portion of the tubular portion 13 in the axial direction, while the base end side surface (plate portion).
- An overhanging portion 13W is provided which is inclined (the surface on the 15 side) and communicates with the tool contact surface 16 of the plate portion 15. According to this configuration, the strength of the support base 12 is improved.
- the surface on the base end side corresponds to the "inclined connecting portion 13R" in the claims.
- the orthogonal hole 18 is formed so as to straddle the plate portion 15 and the overhanging portion 13W.
- the cross-sectional shape of the orthogonal hole 18 is circular, but in the first embodiment, the cross-sectional shape of the orthogonal hole 18 may be circular.
- the orthogonal hole 18 is formed in the support base 12, but as shown in FIGS. 12 to 15, the orthogonal hole 18 may not be formed (in FIGS. 12 to 15).
- the one in which the orthogonal hole 18 is not formed is shown as an example). Even in this case, the base end side portion (the portion having a large inner diameter) of the shaft receiving hole 17 opens to the tool contact surface 16 and the fluid flow can be maintained.
- valve body 25W may be integrally formed with the movable shaft 20. In this case, it is more compact than the configuration in which the valve body 25, which is a separate component, is fixed to the tip of the shaft body 21.
- the orthogonal hole 18 may be formed from the tip end side end portion of the inclined connecting portion 13R to the tip end side (see FIGS. 17 to 19).
- the cross-sectional shape of the orthogonal hole 18 may be rectangular or elliptical. 20 and 21 show that the orthogonal hole 18 has a rectangular cross-sectional shape in the second embodiment.
- the compression coil spring 30 is arranged between the spring locking portion 23 at the base end portion of the movable shaft 20 and the base end side surface 15A of the plate portion 15. As shown, it may be arranged between the lateral protrusion 23Z protruding laterally from the intermediate portion of the movable shaft 20 and the inner side surface on the tip end side of the orthogonal hole 18.
- the base end surface of the support base 12 may be curved rather than flat, and both corners may protrude from the central portion.
- the cross-sectional shape of the orthogonal hole 18 is vertically long, but it may be horizontally long according to the shape of the support base 12.
- valve core according to the present invention is used to open and close the flow path of compressed air, but it is not limited to that used for the flow path of compressed air, and any fluid flows. It may be used for a flow path, for example, nitrogen, oxygen, or a flow path for an air conditioner refrigerant or the like.
