摘要:
In addition to liquid in a thermal volume-neutral stroke transmitter, first and/or second displacement body(ies) is/are positioned in the stroke transmitter, for displacing the liquid. These three materials in the closed system are designed so that the stroke transmitter remains pressure-free during temperature changes.
