Beschreibung
Zusammenfassung:	The invention relates to a linear drive, in particular for moving a gearshift lever in a transmission, comprising a pneumatically or hydraulically movable push rod (11) with which a first piston (14) having at least one pneumatically or hydraulically affected working chamber (16, 18) is associated. According to the invention, the push rod (11) comprises a second piston that can move inside a pressure chamber (21) which is filled with an incompressible medium and which has an opening for admitting and discharging the incompressible medium.
