<p><P>PROBLEM TO BE SOLVED: To provide a valve assembly for avoiding inconvenience such as the wear of a valve or a resulting change of valve timing. <P>SOLUTION: The valve assembly 15 includes a valve body 34 having a valve hole 32. A valve member 36 is slidably arranged in the valve hole 32 between first and second lock positions. First and second valve elements 76, 78 of the valve member 36 have first and second seal faces 80, 82 equally angled with respect to the longitudinal axis of the valve member 36. The first and second seal faces 80, 82 are almost parallel to conically-shaped first and second valve seat faces 112, 114. The first and second valve seat faces 112, 114 are equally angled with respect to the longitudinal axis and adjustably spaced from each other so that the first seal face 80 and the second seal face 82 abut on the first valve seat face 112 and on the second valve seat face 114 at the first lock position of the valve member 36. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
