Abstract
Method and apparatus for compressing gas. Two accumulators are alternately filled with gas from a gas-supplying conduit, and the gas is forced out of one end of the accumulators into a gas-receiving conduit by liquid forced into the other end of the accumulators. A reversible pump moves liquid from one accumulator to the other accumulator. The reversible pump is connected so that pump cavitation is prevented. The invention includes a switching system to switch liquid flow from one accumulator to the other accumulator. Liquid that leaks from the system may be resupplied using a liquid supply system that comprises a pressure container with a compressible element.
