Abstract

A pump includes a cylinder having a working chamber which contains a fluid. A drive system including at least two linear motors which are connected electrically and/or mechanically in parallel moves a piston in the working chamber to bound the working chamber in the cylinder and to pressurize the fluid in the working chamber. A piston rod is connected to the piston and bundles a force applied by the drive system.
