Abstract
A control element () has at least one elastic internal part () that can be connected, via a connection, to a pressurized fluid source and/or a vacuum source, which permits pressurization or evacuation of a cavity in the internal part (). In order to provide a control member for general use, it is proposed that the elasticity module of a wall () bounding the internal part () is formed differently in certain sections such that, instead of a homogeneous increase or decrease in volume under pressurization or evacuation, an oriented change in shape takes place, between a resting state and a pressurized or evacuated state, that describes a control path of the control element ().
