Abstract: A drive for the piston of a linear cooler includes a magnet (6), a linear oscillation coil (3) and a power supply for the coil (3) with a flexible section of line (11) running from a fixed support component (1) to the oscillating coil (3). To increase its life-time, the line section (11) is either made from a bent strip of metal, preferably copper or a copper alloy, or from three components, a metal core, an insulating sheath surround the metal core and a support spring surrounding said sheath.
