Abstract
An activation unit is disclosed having at least one actuator having a variable length disposed around at least one first axis. The activation unit operatively interacts with an activation element mounted so that it can be bi-directionally deflected along a second axis. The front side of the actuator is indirectly or directly engaged with a first piston, which can be deflected along the first axis in a mechanically positively driven manner. The first piston has a front side facing away from the actuator which axially borders at least regions of a transfer medium on one side. The transfer medium is radially surrounded relative to a first axis by a housing radially to the first axis, and axially borders at least regionally a front side of at least one second piston. The at least second piston can be deflected in a mechanically positively driven manner, and engages the activation element directly or indirectly. An actively variable and/or passive temperature control medium is provided on and/or in the housing that is in indirect or direct thermal contact with the transfer medium.
