Patent ID: 8857250

Claim:
A combustion chamber pressure sensor for recording a pressure in a combustion chamber of an internal combustion engine, the combustion chamber pressure sensor comprising: a housing that has an inner space that is at least partially enclosed by the housing; at least one mechanical-electrical transducer element for recording the pressure, the at least one mechanical-electrical transducer element accommodated in the inner space of the housing; at least one diaphragm, the housing having at least one opening and being sealed by the at least one diaphragm, wherein the diaphragm has at least one convex curvature that curves towards and into the inner space of the housing; and at least one pressure transmitting element to transmit the combustion chamber pressure at least partially to the mechanical-electrical transducer element, wherein the diaphragm has at least one fixing on the housing and at least one fixing on the pressure transmitting element, and wherein the pressure transmitting element penetrates through the diaphragm.
