Abstract (en)

A Thermal compensation arrangement (6) comprises a housing (4) including a central longitudinal axis (A). The housing (4) comprises a cavity (14) and a solid state actuator unit (10) being arranged in the cavity (14) and having a first axial end (10a) and a second axial end (10b). The second axial end (10b) acts as a drive side of the solid state actuator unit (10). A thermal compensation unit (8) is arranged at least partially in the cavity (14) and is coupled to the first axial end (10a) of the solid state actuator unit (10). The thermal compensation unit (8) comprises a casing (32) being mechanically coupled to the housing (4) and comprising a recess (34). A piston (36) is axially movable in the recess (34) and is designed to be coupled to the solid state actuator unit (10). The recess (34) is filled with a fluid (MRF) of a viscosity (v) being influenceable by a magnetic field (B). An electromagnet (39) is arranged in the thermal compensation unit (8) and is designed to influence the viscosity (v) of the fluid (MRF) by its magnetic field (B).
