<p><P>PROBLEM TO BE SOLVED: To provide a rupturing plate assembly having a rupturing plate and a rupturing plate holder. <P>SOLUTION: This rupturing plate holder has a first annular member at a downstream side of the rupturing plate, a second annular member at an upstream side of the rupturing plate and an optional third annular member at an upstream side of the second annular member. The outer circumference part of the rupturing plate is held between the first and second annular members. If the third annular member is present, (a) the second annular member is held between the outer circumference part of the rupturing plate and the third annular member, and (b) the third annular member includes fluid ports directed toward the rupturing plate. However, if the third annular member is not present, the second annular member includes the fluid ports directed toward the rupturing plate. This invention in another preferred embodiment provides a device access assembly including a device access cover, a device access cover mount and an annular member between the device access cover and the cover mount. <P>COPYRIGHT: (C)2004,JPO</p> |
