The expansion material can be controlled by setting processes. The working element according to the invention now works with expansion material, which, together with the working piston, is no longer sluggish when it is used as a control element in a housing with good thermal conductivity, but rather becomes a surprisingly fast dynamic. foolish rain behavior around a quick reaction of the working piston. To achieve such a small, as quick as possible with warm applied line constants, it can be used for purposes of use, and in addition, the heat must also be set, in which the dynamic, direct behavior on the housing of the expansion joint is particularly important. einfließen.
