Linear Drive

Abstract

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 scaling 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.
