As shown in FIG. 2 and FIG. 3, the narrow air scavenging passage 25 matching the air flow hole 21 is disposed to one end of the cover 22 ending in the vicinity of the cooling port 24. As shown in FIG.

본원 고안에 있어서는 케이스프레임(2)의 구동기구실(3) 내에 설치되는 구동기구(16)의 마찰열등에 의해 가열되어서 고압이된 공기는 공기유통공(21)에서 곧바로 외기중에 방출되지 않고, 커버(22)의 내면이 공기빼기 통로(25)를 통과하여 커버(22)의 한쪽끝에서 외기중에 방출되는 것으로, 이 통로(25)의 출구가 모터상자체(23)의 냉각구(24) 부근에 있으면, 냉각구(24)에서 분출하는 공기의 아웃젝트 작용에 의해 배출을 보다 더 촉진할 수가 있다.In the present invention, air heated by friction heat or the like of the drive mechanism 16 installed in the drive mechanism chamber 3 of the case frame 2 is not discharged to the outside air immediately from the air distribution hole 21, and the cover ( The inner surface of 22 passes through the air bleeding passage 25 and is discharged to the outside air from one end of the cover 22. The outlet of the passage 25 is located near the cooling port 24 of the motor box 23. If present, the discharge can be further promoted by the injecting action of the air blown out by the cooling port 24.

본원 고안은 파이프절단기(1)의 케이스프레임(2)의 외주를 피복하여 고정한 커버(22)의 내면에 상기 프레임의 대략 밀폐된 구동기구실(3)의 측벽에 형성한 공기유통공(21)에 통하는 좁은 공기빼기통로(25)를 커버(22)의 한쪽끝에서 외기로 향해 개방하여 배설한 구성을 가지며, 밀폐상태의 구동기구실(3)의 내부에서 톱부착로드(9)를 왕복구동하기 워한 구동기구(16)의 기계운동에 의해 마찰열을 발생하여 이 기구실(3)내에서 고압이 되어서 외기와의 압력차를 일으키는 경향이 되어도, 공기유통공(21)에서 커버(22)이 공기빼기 통로(25)를 통과하여 외기중에 배출되며, 외기압력을 균형되게하는 동시에, 공기유통공(21)은 직접 외기로 향해서 개방된 것이 아니므로, 파이프절단기(1)를 사용하지 않는 동안 또는 사용중에, 오염된 외기가 이 유통공(21)으로부터 구동기구실(3)에 침입하여 먼지를 이 기구실(3)의 내벽 또는 구동기구(16)에 부착하여, 사용중의 마모를 촉진할 염려가 없고, 파이프 절단기의 관리를 양호하게 유지할 수 있으며, 더욱이 상기와 같은 그리스의 고온고압에 의한 용촉(溶)유동 등을 잘 방지할 수 있는 효과가 있다.The present invention devises an air flow hole 21 formed in the side wall of the drive mechanism chamber 3 which is substantially sealed on the inner surface of the cover 22 which covers and fixes the outer circumference of the case frame 2 of the pipe cutter 1. It has a configuration in which the narrow air bleed passage 25 through which it opens is opened and discharged from one end of the cover 22 to the outside air, and it is difficult to reciprocate the top mounting rod 9 inside the drive mechanism chamber 3 in a sealed state. Even if the heat of friction is generated by the mechanical motion of the drive mechanism 16 and becomes high pressure in the mechanism chamber 3, it tends to cause a pressure difference with the outside air. While passing through the passage 25 and being discharged into the outside air, the outside air pressure is balanced, and the air distribution hole 21 is not directly open toward the outside air, so that the pipe cutter 1 is not used or in use. The polluted outside air is driven from this distribution hole 21. By adhering to the chamber 3 and attaching dust to the inner wall of the mechanism chamber 3 or the drive mechanism 16, there is no fear of promoting wear during use, and it is possible to maintain the pipe cutter well. By high temperature and high pressure of grease ) It is effective to prevent flow.
