<p><P>PROBLEM TO BE SOLVED: To provide a revolution introduction part allowing only comparatively small leakage. <P>SOLUTION: The first end area of the tubular part 3 is inserted into and engaged with a hole 4 in the first component 1, and the second end area of the tubular part 3 is inserted into and engaged with a hole 5 in the second component 2. The first end area of the tubular part 3 is sealed by a piston ring 9 to the inner wall of the hole 4 of the first component 1, and it is moreover freely and relatively revolvable to the first component 1. An O-ring packing 7 is automatically tightened to the inner wall of the hole 5 of the second component 2 and the tubular part 3 is formed so that it revolves at the same speed as the second component 2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
