摘要： A pressure-measuring device (1) is used for arrangement in a chamber of an internal combustion engine. The pressure-measuring device (1) has a housing (3), a force transmission element (5) which partially projects from the housing (3) at a chamber-side opening (6) in the housing (3), and a pressure sensor (19) which is arranged in an interior (11) of the housing (3). In this case, the pressure sensor (19) is operatively connected to the force transmission element (5). Provision is also made of a diaphragm (10) which seals the interior (11) of the housing (3), in which the pressure sensor (19) is arranged, with respect to the chamber-side opening (6). The diaphragm (10) which is preferably in the form of a metal diaphragm has a force transmission section (23) which is oriented in an axial direction of the force transmission element (5). In addition, the pressure sensor (19) is operatively connected to the force transmission element (5) by means of the force transmission section (23) of the diaphragm (10). As a result, thermally induced changes in the length of the diaphragm (10), which are caused, for example, by hot fuel gases and result in periodic impairment of the pressure measurement using the pressure sensor (19), are at least partially compensated for.

摘要： The invention relates to a pressure gauge (1) that is designed to be located in a chamber of an internal combustion engine. The pressure gauge (1) has a housing (3), a force transmission element (5), which interacts with a pressure sensor (24) and a centring element (19). The pressure sensor (24) is joined, together with contact plates (22, 23) to a centring section (21) of the centring element (19), allowing the pressure sensor (24) and the contact plates (22, 23) to be positioned inside the housing (3) of the pressure gauge (1). This simplifies the assembly of the pressure gauge (1) and optionally permits pre-assembly.

摘要： The invention relates to a pencil-type glow plug (1) for arranging in an internal combustion engine chamber. Said pencil-type glow plug (1) comprises a housing (3), a bar-shaped heating element (2) and a pressure sensor (21). The bar-shaped heating element (2) extends from the housing (3) on an end-sided opening (4) of the housing (3). Also, the pressure sensor (21) is arranged in an internal chamber (16) of the housing (3). Pressure prevailing in the chamber impinges upon the heating element which is transferred to the pressure sensor (21), in order to enable said pressure sensor to determine the pressure prevailing in the chamber. Said determination can be impaired by deposits, in particular coke residues, on the end-sided opening (4), which is undesired. In order to prevent said impairments, a sealing chamber (17), which is adjacent to the end-sided opening (4), is arranged in the housing (3), and is filled with a sealing agent (35).
摘要翻译：本发明涉及一种用于布置在内燃机室中的铅笔型电热塞（1）。所述铅笔型电热塞（1）包括壳体（3），棒状加热元件（2）和压力传感器（21）。棒状加热元件（2）从壳体（3）延伸到壳体（3）的端侧开口（4）上。而且，压力传感器（21）布置在壳体（3）的内室（16）中。在腔室中占主导地位的压力撞击传递到压力传感器（21）的加热元件，以便使所述压力传感器能够确定在腔室中占主导地位的压力。所述测定可能由于不希望的端侧开口（4）上的沉积物，特别是焦炭残余物而受到损害。为了防止所述损伤，在所述壳体（3）中布置与所述端侧开口（4）相邻的密封室（17），并且填充有密封剂（35）。

摘要： In order to, in particular, control an engine based on combustion chamber pressure signals, a combustion chamber pressure inside the combustion chamber of an internal combustion engine has to be measured. To this end, a sheathed element glow plug (110) for a self-igniting internal combustion engine is provided, which has a heating element (122) and a plug shell (112). The plug shell (112) has at least one force measuring element (130), which is connected to heating element (122) in a manner that enables a force (126) to be transmitted to the at least one force measuring element (130) via the heating element (122). The sheathed element glow plug (110) also comprises at least one sealing element (148), which is joined to the heating element (122) and which has at least one element (148) with an elastic property. The at least one sealing element (148) seals the heating element (122) from the plug shell (112).
