The air gap 58 is closed to prevent the air groove 56 from being ventilated; and the high-pressure air in the milk flow passage 21 can be sequentially passed through the air inlet 44, the guide groove 45, the neck hole =, the tube hole 54, and the air groove 56. And the air guiding hole 55 is introduced into the air chamber 24 under the valve body 3, and the force of the outer spring 7 can be combined to push the movable cymbal 4 from the bottom to the top, and the T air chamber 24 is inward. The thrust of the compressed air or the thrust plus the force of the outer spring 7 is the force in which the high-pressure air in the intake runner 21 induces the downward displacement of the movable valve 4, so that the live valve 4 can remain in the upright position, so that the activity Read*: The upper air stop ring 46 can close the main valve hole 3〇, because::11 inside the medium piston 丨2 hit the nail, so it can be kept stable: ΐ change ^ operator squeeze the trigger 6 (as shown As shown), the inner spring 8 is pressed upwards, so that the front portion of the valve stem 35 and its front and inner ring 37 are implanted into the (four) hole 54. 'close the pipe hole 54 and the air groove two: The height of the passage 21 into the pipe hole 54 is: and the inner air chamber 24 is guided through the air groove 56 and the air guiding hole 55. == The middle air stop ring 36 on the method 35 has opened the air gap (4) The external passage: the rod 10 1263565 Therefore, the high-pressure air originally collected in the lower air chamber 24 is discharged to the outside through the air gap 58 to the lower side, and the force of the external spring 7 can be increased less than the action of the high-pressure air to push the movable valve. Therefore, the high-pressure air in the intake passage 21 quickly pushes the movable valve 4 downward, so that the movable reading 4 is in a lowered position in the valve seat 3 (as shown in FIG. 3), and the upper layer of the movable valve 4 is stopped. The ring 46 opens the main valve hole 30, so that high-pressure air can be carried in the top venting chamber 14 via the main reading hole 3, the upper air chamber, the vent 32 and the cylinder passage 2, and the ejector rod 13 on the piston 12 is driven. Quickly firing the nail member' thereby constructing a trigger valve configuration technique that can quickly fire the nail member after the trigger trigger 6; at the same time, the activity The middle air retaining washer 47 of 4 closes the inner valve hole 3 so that the high-pressure air in the upper air chamber 23 cannot be loaded into the exhaust hole (10) and the exhaust flow passage 22, so that the high pressure in the upper air chamber 23 can be avoided. Air pressure maintains the stability of quick nailing. In addition, after firing the nail member, the operator releases the trigger 6, and the valve stem 35 is quickly returned to the original position by the restoring force of the inner spring 8 (as shown in FIG. 4).
