[origin: WO2015090288A2] The invention relates to a conveying device for a fluid, comprising a motor coupled to a pump (1). The pump (1) comprises a double piston (3), which is movably supported in a cylinder (2) and has a piston rod (4) on one side, which is detachably connected to the motor in a force-closed manner in such a way that there is a connection only if the charge pressure on a working side of the double piston (3) is less than a target pressure, the cylinder (2) is coupled to a supply (9) on the side facing the piston rod (4), and the cylinder (2) is connected on the side facing away from the piston rod (4) to the working side and and the supply (9) by means of valves.
