The invention concerns an important innovation for combustion engine research, whereby thermal shocks overlaid upon the pressure cycles are compensated. For this a diaphragm construction is proposed consisting of an annular plate and central plate, which is joined to an annular support in such a way that a bridge girder structure with double parallelogram support results. The position and thickness of the central plate are optimizable, and it serves as an actuator element for controlling the compensation process via the double parallelogram structure. At the same time, the central plate is raised to a significantly higher temperature level by controlled heat conduction paths. A novel thermal shock compensation is achieved by these two measures. Further improvement is possible by stepwise optimization of the central plate, by turning it on a lathe and comparing it in the test engine for example.
