The invention pertains to a device for compressing gas, with a housing that contains a separating element along which a piston, moved by a drive mechanism, passes through two dead-center positions. By providing a three-stage compression cycle, with the piston together with the housing delimiting three successive separation chambers for containment of the gas to be compressed, the invention creates a gas-compressing device with which a high compression value can be attained at low cost for assembly and maintenance and which is reliable in operation.
