Abstract

The invention relates to a linear drive having a housing (1) with an end plate (EP) and with a front plate (SP), and having a piston (2) which is movably arranged in the interior of the housing and which is connected to a piston rod (KS). The front plate, which is fixedly connected to the housing, has an opening for leading the piston rod out of the housing, wherein the front surface is sealed off with respect to the movable piston by a first bellows system (7). The piston in the interior of the housing has a substantially cylindrical widened portion which is arranged around the central supply. The actuator is characterized in that at least one flexible element (6) connects the substantially cylindrical widened portion of the piston and the central supply line, and in that a second bellows system (3) is arranged between the substantially cylindrical widened portion of the piston and the end plate or the housing in such a way that two cavities separated from one another in a gas-tight manner are thereby formed in the interior of the actuator, wherein the means for supplying and discharging the first fluid medium (M1) are connected to the first cavity (5), and the means for supplying and discharging the second fluid medium (M2) are connected to the second cavity (4).
