    Abstract: The invention relates to a device for transporting fluids, comprising an internal combustion engine, preferably having symmetric free floating step pistons. In order to transport liquid in a reliable manner and with a high flow rate, the step piston (14) comprises a continuous axial recess (64) which surrounds a fixed pipe element (72) on one end of the step piston in a coaxial manner, along the length thereof, whereby the step pistons (14, 18) can be sealingly displaced back and forth in relation thereto.

    Abstract: A two-stroke combustion engine is described which has a symmetrical, floating differential piston (14), having at least two main piston portions (16, 18), each movable in a combustion chamber (28, 30) formed with exhaust ports (46), and each connected to a pre-compression chamber (34, 36) by means of a respective channel (38, 40). The combustion chambers (28, 30) are arranged axially inward of the piston portions and between the chambers lies the pre-compression chamber (32) in which a central double-acting piston portion (22) of the differential piston (14) is arranged on a piston rod (20). The central piston portion (22) divides the pre-compression chamber (32) into two separate supercharging chambers (34, 36), from which the channels (38, 40) leading to the combustion chambers (28, 30) terminate at the end walls of the respective combustion chambers. Valve means (24, 26) on the piston rod (20) serve to open and close the channels so that upon expansion occurring in one combustion chamber material exchange will occur in the other.
