Abstract:
1. A hydraulic pressure intermediary, comprising: a platform, which has an essentially axi-symmetric, bowl-shaped surface having a flat, annular, platform-surface edge region, a platform-surface central region depressed relative to the platform-surface edge region and surrounded by the platform-surface edge region, and an annular platform-surface transition region, which borders, on its inner side, the platform-surface central region and, on its outer side, the platform-surface edge region; and an essentially axi-symmetric, bowl-shaped, separating membrane having a flat, annular, separating-membrane edge region, a separating-membrane central region depressed relative to the separating-membrane edge region and an annular separating-membrane transition region, which borders, on its inner side, the separating-membrane central region and, on its outer side, the separating-membrane edge region, wherein: said separating membrane is connected with said platform-surface edge region within said separating-membrane edge region along a surrounding joint, in order to enclose a cavity filled with a pressure-transfer liquid, wherein the cavity communicates with a hydraulic path through an opening in the surface of said platform; said separating-membrane transition region includes an annular moat having a moat outer side, a moat inner side, and a moat transition zone, wherein said moat outer side has a first annular, inclined surface, which borders on said separating-membrane edge region, said moat inner side includes a second annular, inclined surface, which borders on said separating-membrane central region, and said moat transition zone extends between the first and the second inclined surfaces.
