PROBLEM TO BE SOLVED: To provide a pressure measuring device capable of certainly measuring pressure over service life by improving the sealing action of the pressure measuring device to an inner chamber. SOLUTION: The pressure measuring device 1 to be arranged in the inner chamber of an internal combustion engine comprises a housing 3, a force transmitting body 2 partially projected from the housing 3 in an opening 5 on the chamber side in the housing, and a pressure sensor 15. The pressure sensor is arranged in the inner chamber 4 of the housing 3, is at least indirectly action-coupled to the force transmitting body 2, and has at least one elastically deformable seal element 28. The seal element is arranged inside the housing 3, the inner chamber 4 of the housing 3 is sealed from the opening 5 on the chamber side in the housing 3. A flame shield 29 for protecting the seal element 28 from the effect of the heat on the chamber side is provided. COPYRIGHT: (C)2008,JPO&INPIT |
