A method of operating a piston expander, including introducing live steam into a cylinder space via an inlet valve; expanding the live steam during a power stroke in which a piston moves from an upper dead center position to a lower dead center position; opening an outlet opening as soon as the piston is in the region of the lower dead center position; after the piston reaches the lower dead center position, conveying the expanded steam out of the outlet opening and into a steam discharge; and subsequently closing the outlet opening before the piston in an exhaust stroke reaches the lower dead center position.
