Claims

[Scope of utility model registration request]

The large diameter part 11a of the joint body 11 consists of a large diameter part 11a having a sealed copper pipe to which the pipe on the outdoor unit side is connected to the open end, and a small diameter part 11b to which the pipe on the indoor unit side is connected. A vertical port portion 11c into which a spindle 17 is fitted is provided in the center of the upper portion, a slope 11d communicating with the fluid passage on the small diameter portion side is provided deep inside the large diameter portion 11a, and a center through hole 13a is provided in the large diameter portion 11a. A ball valve 13 is disposed in contact with the slope 11d and has an elastic sealing material 1 at the inner end adjacent to the opening side.
4a and a push ring 14 having an O-ring 14b on the circumferential surface, a retainer ring 15 secured to a part of the copper pipe 12 outside the open end of the large diameter portion 11a, and a retainer ring A coil spring 16 is disposed between the push ring 15 and the push ring 14, and the spring force of the coil spring 16 presses the elastic sealing material 14a against the opening side circumferential surface of the ball valve 13. The lower end of the spindle 17 is engaged with the lower end of the spindle 17, and a valve core 24 is provided inside at the center of the side of the large diameter portion 11a at a required angle from the center line of the vertical port, and the center of the ball valve 13 when closed. A joint fitting for an air conditioner, which is provided with a charge port part 23 communicating with a through hole 13a.
