An electrochemical actor with a closed gas chamber has a plurality of stacked cells (7), each of which contains a solid electrode of an electrochemically reversibly oxidisable material and a gas-generating or consuming counter-electrode, whereby a rise of fall in pressure convertible in one movement is effected by a reversible d.c.-generated electrochemical reaction cycle in the gas chamber. To limit the gas formation and vertical movement there is a mechanically actuatable electric switch, the actuating member (14) of which is arranged in the path of movement of an adjuster (4) to which gas pressure is applied in such a way that, when the adjuster (4) reaches a predetermined end position, the connecting line to the d.c. source is interrupted. |
