Abstract: The invention relates to a sealing unit for a fuel pressure sensor for sealing an at least virtually flat sealing joint between the sensor and a component that carries it via a screw connection, wherein a round sealing washer with a central bore is disposed between the threaded bolt-shaped end of the sensor housing with its central sensor bore and the bottom of the threaded bore of the component with its central pressure fluid opening. A pin is formed onto the threaded bolt-shaped end of the sensor housing, which pin centers the sealing washer, fixing it in a positive and/or frictional, non-positive manner, and rises above an end face that serves as a bearing surface for the sealing washer. The pin ends in an end face and has a length that is shorter than the thickness of the sealing washer. A sealing unit is produced that assures a reliable sealing function and permits a simple installation and disassembly of the sealing washer while reclaiming the sealing washer in a sealing position.

Abstract: Shaped articles made of brittle material having a low coefficient of thermal expansion, for example designed as glass or glass-ceramic plates, are typically encapsulated with a holding frame made of plastic, which is produced by directly encapsulating the edges of the shaped article with plastic by injection moulding. In order to avoid stress concentrations in the shaped article, which inevitably form as a consequence of the differences in thermal expansion and the material-dependent shrinkage behaviour, according to the invention shrinkage-absorbing elements are embedded between the holding frame and the shaped article, which elements additionally ensure a permanently elastic bearing of the shaped articles when used in practice and provide sufficient sealing during use.
