Abstract: A pressure sensor measuring element for a pressure sensor operates to detect pressure in a combustion space of an internal combustion engine. The pressure sensor measuring element includes a separating diaphragm, a plunger for the transmission of deflections of the separating diaphragm to a force measuring element, and with a sleeve which receives the plunger. The sleeve is closed by the separating diaphragm at a first end intended to face the combustion space and is designed to hold the force measuring element at the opposite second end. Accordingly, the pressure sensor measuring element can be produced more cost-effectively. Furthermore, the plunger can be produced in one piece with the separating diaphragm as a diaphragm/plunger unit, and the sleeve and the diaphragm/plunger unit can be formed from the same metal material.

Abstract: The locking device comprises a coupling element (5). It can be brought into a first and a second coupling condition in an electronically controlled manner by drive means moving the coupling element. A drive-off element (4) can be connected to locking means. In the first coupling condition, the rotor is decoupled from the drive-off element in the sense that no direct coupling via the coupling element or an other coupling means is present that would mean that the rotation of the rotor would cause a movement of the drive-off element. In the second coupling condition, the coupling element couples the drive-off element with the rotor (2), which may be operated by means of a key, door handle, door knob or similar means, or by an electrical actuation.
