摘要： This spark plug comprises: - a central electrode (2), - an insulating core (6) bearing the central electrode (2), - an external body (8) in which the insulating core (6) is mounted and which has a region (18) where the external body (8) is crimped onto the insulating core (6), and - a force sensor (30). The force sensor (30) is mounted at the periphery of the external body (8) between, on the one hand, a bearing element (38) secured to a first peripheral region of the external body (8) and, on the other hand, a second peripheral region (24) of the external body (8). The second peripheral region (24) of the external body (8) is further away from the crimping region (18) than the first peripheral region. The bearing element (38) is prestressed against the force sensor (30).

摘要： The inventive body (8) is provided with a thread (16) on the external surface thereof for screwing said body (8) into a corresponding internal screw thread of an engine and with a gripping area (28) generally embodied in the form of a cylinder having a hexagonal section for gripping said body (8) and screwing a glow plug (2) into a corresponding internal screw thread. The external diameter of the body section between the thread (16) and the gripping area is along the entire height thereof at least equal to or greater than the external diameter of the threaded section (16). Said invention can be used for internal combustion engines, in particular for diesel engines.

摘要： The invention relates to a device which is used as a force-transmitting device (38') for a pressure sensor (14) associated with a glow plug in an internal combustion engine and is embodied in the form of a tubular piece whose cross-section is substantially annular. The inventive device comprises an area (40) on which the external diameter thereof increases towards one end thereof. The front surface of the device corresponding to said flared end is embodied in the form of a bearing face receiving the piezo-electric pressure sensor. A glow plug integrating said force-transmitting device is also disclosed.

摘要： The preheater plug (1) comprises a tubular body inside which a pressure sensor (90) is mounted, said pressure sensor measuring the internal pressure of an engine cylinder wherein the plug (1) is arranged. The pressure sensor is provided with connection lugs extending in a substantially longitudinal manner in relation to the axis of the tubular body. The body (10) has a lateral groove in the inner lateral wall. At least one connection lug is engaged in said groove.
