OPTIMISATION OF DEAD SPACE IN PISTONLESS COMPRESSORS

摘要

The invention relates to a device for compressing a gaseous medium, more particularly hydrogen, oxygen, helium, nitrogen or argon. Said device comprises a) one or more cylinders (1) filled with a liquid (2), b) feed (4) and drain lines (5) for feeding and draining the gaseous medium to and from the cylinder (1), said lines being situated in the vicinity of the upper end position of the liquid column (2), c) at least one liquid line per cylinder (1), said line feeding and draining the liquid (2) that compresses the gaseous medium to and from the cylinder (1), and d) means for modifying the quantity of liquid (2) in the cylinder or cylinders (1). According to the invention, the cylinder or cylinders (1) are arranged in such a way that its or their longitudinal axis or axes is/are tilted in relation to the horizontal.
