摘要： The sensor for measuring the pressure of a medium comprises a wire (5) the resistance of which varies in accordance with the pressure. The wire (5) is placed within the medium in a coil or pleated form or the like. Preferably a portion (5a) of the wire is protected from the pressure. The protected portion (5a) of the wire and the portion (5b) exposed to the pressure are forming the branches of a bridge circuit. In order to measure the combustion pressure in combustion machines, circuits are located in the chamber (11) of a spark plug or disposed with the electric conductors (21) (44) of an incandescent plug. Combustion pressures may thereby be obtained by controlling and/or adjusting injection and/or ignition systems without further borings. In other embodiments of the sensor high pressure may also be measured, for example the pressure in an injection pump.

摘要： An actuator module (20; 40) comprising a piezoactuator (21; 41), for example for a piezoinjector for metering fuel in an internal combustion engine, is proposed, wherein the piezoactuator (21; 41) has piezoelements (24; 44) stacked one above another between an actuator head (22; 42) and an actuator foot (23; 43) and is provided with at least one elastomer layer (25; 45) enclosing the piezoelements (24; 44). The elastomer layer (25; 45) is enveloped by a corrugated bellows (26) or by telescopic tubes (46, 47), composed of a material that is diffusion-impermeable with respect to a fuel to be metered by means of the piezoinjector, and the corrugated bellows (26) or the telescopic tubes (46, 47) have on their periphery grooves which can absorb expansions of the elastomer layer (25; 45) or of the piezoactuator (21; 41).

摘要： A control valve (13) is proposed for actuating a control chamber (20) of a fuel injector with a valve element (25) and a valve sleeve (30). The valve sleeve (30) is guided in an axially movable manner and presses with a closing force against a valve seat (38) which is formed on the valve element (25). The valve sleeve (30) is guided by way of an outer circumferential surface (34) in a guide sleeve (50) which is formed as a component which is separate from the valve element (25). A hold-down spring (47) acts on the guide sleeve (50) in such a way that the guide sleeve (50) rests on the valve element (25) in a self-centring manner with respect to the axis of a conical outer surface (28).

摘要： Disclosed is a multilayered actuator provided with a stack (31) of thin insulating layers (20) made of a piezoactive material, wherein incorporated inner electrodes (21,22) alternatingly leading out of said stack (31) are electrically connected in parallel via outer electrodes (23,24) which are respectively associated with one side of the stack (31). At least one of the outer electrodes (23, 24) has a conducting layer (15) and an interwoven structure (5) which is connected to the conducting layer (15) in certain places, whereby said interwoven structure is embodied in such a way and connected to the conducting layer (15) in such a way that forces arising during the operation of the multilayered actuator in the region of the outer electrodes (23,24) as a result of a longitudinal contraction/longitudinal dilation of the stack (31) can be at least substantially compensated inside said interwoven structure (5). The interwoven structure especially comprises weft threads (10) and warp threads (11) which form lozenged gaps or meshes (12) with an inner angle (16) which is adapted to the piezoactive material
