The invention relates to a fluid linear drive having a cylinder 1 which is entirely or partially filled with a pressure medium. A piston 2 is arranged inside said cylinder so as to be displaced and has a piston rod 10 which is arranged at one end of the piston 2 and is led out of the cylinder 1 in a sealing manner. The piston subdivides the interior space of the cylinder into a first chamber 6 and a second chamber 7, the piston rod 10 extending through the second chamber 7. A pump 17, which is particularly reversible and by means of which the pressure medium can be pumped into the first chamber 6 and pumped off from the first chamber 6, has a first intake and/or pressure connection 18 and a second intake and/or pressure connection 19. The first intake and/or pressure connection of the pump 17 is connected to the first chamber 6 and the second intake and/or pressure connection is connected to a storage chamber. The pump 17 is mounted in the piston 2 or in or on a bottom of the first chamber.
