ンケースを冷却するようにしている。Reference numeral 10 denotes a packing case in which a rod fitting is housed, and 11 a distance piece for removing the packing case 10. For example, in an oil-free reciprocating compressor, the rod gasket provided in the nozzle case 10 deteriorates the mechanical properties of the rod gasket due to frictional heat between the sliding portion of the rod gasket and the piston rod 6, causing deformation due to softening. and the resistance to wear is significantly reduced. In order to prevent this, conventionally the case has been cooled.

さ扛ている。The detailed structure of the packing case 10 shown in FIG. 1 is shown in FIG. 2. As shown in the figure, the packing case 10 is composed of a gland cover 12 and several cases 14 that house the inner mK gland packing 13. Each case 14 and the gland cover 12 are integrally connected by a through bolt 15. ing.

、第３図に示すように円弧状の＃１１８と線溝１８の端
部から軸方向に貫通ずる通路孔１９が形成されている。The packing case 10 thus constructed was inserted into the inner cylinder cover 4 and fixed to the inner cylinder cover 4 with bolts 16. In order to cool the rod packing 13, cooling water supply holes 17 are formed in the gland cover 12 of the packing case 10, and arc-shaped #118 holes are formed in each case 14 as shown in FIGS. 2 and 3. A passage hole 19 is formed that passes through the end of the wire groove 18 in the axial direction.

にこぼ扛るのを防ぐためである。However, as shown in the figure, the cooling water passage has a very irregular shape, and the machining of the arc-shaped groove 18 in particular cannot be done using a general-purpose machine tool such as a lathe. There was a drawback that it was not. The packaging case 10 includes a case 14 of several bales and a ground cover 12 and a bolt 1.
It must be installed into and removed from the inner cylinder 4 while connected at 5. The reason is that each case 14
This is to prevent connection with the through bolt 15 unless the positioning is accurate, and to prevent the cooling water collected in the groove 18 from spilling onto the piston rod 6 during the gap when the gasket case is removed.

Since the case 144'i is integrated with the through bolt 15, it is necessary to take out the entire packing case 10 from the machine, and in order to take the packing case 10 out of the machine, the piston rod 6 must also be taken out to the cylinder 1 side. It was difficult to maintain and had poor maintainability. Furthermore, since the passage area of the cooling fluid connecting the cases 14 cannot be made very large, the flow rate of the cooling fluid cannot be increased, resulting in a low cooling capacity.

A circumferential groove 24 is formed in the end surface of the end case 14a on the case 14 side so as to communicate two types of radial through holes 22 and 23 formed in the case 14. The ground cover 12 has a circumference @2 formed on the inner circumferential side of the case 14 located closest to the ground cover 12.
a cooling fluid supply hole 25 communicating with the case 14;
A cooling fluid discharge hole 26 communicating with the circumferential groove 21 formed on the outer peripheral side of the cooling fluid is formed. With this configuration, each case 14 and the end case 14a.

It is sufficient to assemble the A1 case 14 and the ground cover 12 one by one in this order. Therefore, in order to assemble the packing case 10, it is not necessary to make the distance piece 11 (see Fig. 1) long and eggplant. By fixing the gland cover 12 to the inner cylinder 4 with bolts 16, the entire packing case 10 can be fixed at the σ position.

にくく冷却効果が大きくなる。The cooling fluid supplied from the supply hole 25 of the ground cover 12 enters the circumferential groove 20 on the inner circumferential side of the case 14 and circulates in the circumferential direction.
It passes through the through hole 22 on the inner circumferential side, passes through the circumferential groove 20 and through hole 22 of the next case 14, makes a U-turn at the circumferential groove 24 formed in the end case 14a, and then passes through the circumferential groove 20 and through hole 22 of the next case 14, making a U-turn at the circumferential groove 24 formed in the end case 14a, and then passing through the circumferential groove 20 and through hole 22 of the next case 14. The liquid enters the through hole 23, passes through the circumferential groove 21 on the outer circumferential side, passes through the through hole 23 of the next case 14, and the circumferential groove 21, and is discharged from the discharge hole 26 formed in the ground cover 12. Cooling fluid flows around the circumference @20.21.24 and through hole 22.2
3. When passing through each case 14゜148' (f-, the rod packing 13 can be cooled through the through hole 2.
2. Since a large number of 2.23 can be provided in the circumferential direction, the passage area of the cooling fluid can be made sufficiently large as desired, so that the cooling fluid such as cooling water can flow sufficiently and the flow layer is also large. Totame and other scales are less likely to adhere, and the cooling effect is greater.

が可能である。Next, a procedure for replacing the rod gasket 13 due to wear or deterioration of the rod gasket 13 will be described. When the supply of cooling fluid is stopped, all of the cooling fluid in the packing case 10 flows to the lowest part of the circumferential grooves 21 and 24 due to the circumferential grooves 20 and 21, and the discharge hole 2
6 to the outside, all of the cooling fluid in the packing case 10 can be discharged. Therefore, even if the paragin case 10 is disassembled inside the machine without being taken out of the ship, there is no risk of the cooling fluid adhering to the piston rod 6, etc., so the bolts 16 are removed, the gland cover 12 is
Valley case 14. The end cases 14a can be individually moved in the axial direction in this order. The rod packing 13 generally includes two packing members 13a and 1 divided in the circumferential direction.
3b and a garter spring 13c provided on the outer circumferential side of the packing members 13a and 13b, so by removing the garter spring 13ci, the packing members 13a and 13b2 can be removed to the outside and replaced with a new packing member. Can be exchanged. According to this embodiment, the rod fittings 13 can be replaced without removing the piston rod 6 or removing the packing case 10 from the machine (9). Furthermore, there is no drawback that the distance piece 11 must be made completely long in order to take out the packing case 10, and the compressor as a whole can be made more compact.
また、本実施例では、冷却流体の通路は円周溝と円形の
