摘要： A sealing arrangement of a piezoactuator (12) for a fuel injection valve of an internal combustion engine, has connecting pins (14) projecting out of the piezoactuator (12) and a head arrangement (16, 18) placed on to the piezoactuator (12), which is provided with openings (20) for the penetration of the connecting pins (14), wherein a liquid-tight sealing element (30) abuts against the outer surfaces of the connecting pins (14) on one side and also against the head arrangement (16, 18) on the other. In order to ensure a reliable seal with this arrangement, in particular also over extended periods of time, the sealing element (30) abuts against the outer surfaces of the connecting pins (14) located inside the openings (20), and sealing element sections (32) located inside the openings (20) are radially compressed in the openings.

摘要： A device (10) has a contact surface (22) arranged laterally offset and essentially extending tangentially in relation to an insertion section (16), which, on introduction of the insertion section (16) into a housing opening, interoperates with a corresponding contact surface of the housing providing torsional stability, with the contact surface (22) of the connecting device (10) being embodied at areas of the contact surface tangentially opposite one another in each case with a plastic deformable contact surface projection (24) and/or the circumferential area of the insertion section having an annular closed area of the cylindrical surface on which a number of elastic, sprung, centering projections (20), projecting radially from the area of the cylindrical surface are provided which are arranged at intervals from one another around the circumference. This makes possible a functionally-optimized and tight-fitting interoperation between the corresponding contact surfaces.

摘要： Subsequent to their placement on a housing, known connection devices (e.g. contact stud carriers) are often not in a location that is exactly defined. A connection device which ensures significant positional accuracy in a simple manner has a locating face (22) which is laterally offset and extends essentially tangentially relative to an insertion section (16). The locating face interacts with a corresponding locating face of the housing in an anti-rotational manner when the insertion section (16) is inserted in a housing opening. The locating face (22) of the connection device (10) is formed both inelastically and elastically (28) at locating face areas (24, 26) which are opposite to each other. This allows a “backlash-free” interaction between the corresponding locating faces and, therefore, a particularly accurate positional definition.

摘要： The sealing element consisting entirely of elastomer is plugged onto the head plate of a piezo actuator for a fuel injection valve. Encircling sealing bulges (6) are formed on the first end of the sealing element and effect a sealing toward the injector body (2). The sealing element has passages for accommodating contact pins (7), whereby sealing lips (8) are formed around the passages in order to seal the contact pins (7). The sealing actions of the sealing bulges (6) and of the sealing lips (8) are separate from one another.

摘要： In a method and arrangement for sealing a piezoactuator having terminal pins (12) protruding from the piezoactuator and a top plate (14) surmounting the piezoactuator, the top plate is provided with openings (16) to enable the terminal pins (12) to pass through. In order to ensure a reliable seal even for comparatively thin top plates (16) in particular, the invention proposes placing an O-ring (28) made from an elastic sealant material on each of the terminal pin sections (30) protruding from the openings (16), so that said O-ring fits tightly to a circumferential surface (32) of the terminal pin section (30), as well as to the top plate (14), forming a seal, and being pressure-injected into the top plate (14) by means of a plastic extrusion coating (arrows in FIG. 1).
