A B S T R A C T O F T H E D I S C L O S U R E In piston driven machines and in particular those having an elastically deformable sealing tube between the piston and the cylinder, which causes a relatively large structural length of the cylinder-piston arrangement and which may be provided with a forced feed for the lubricant, a reduction in the space requirement, in particular the structural length of the cylinder-piston arrangement is achieved by a driving mem- ber slidably mounted on a tubular cylinder externally and ex- tending over at least part of the length of the cylinder, and frictionally connected to a rotating driving mechanism. A pulsating secondary space formed by the driving member at the outside of the cylinder is connected for the avoidance of shock pressures because of filling with lubricant liquid flo- wing away, through a balancing channel of large cross-section- al area to a pressure-balancing chamber. For further reduc- tion in the space requirement the often necessary lubricant cooling may be effected by means of a heat exchanger to which the lubricant and the working medium of the piston machine are admitted and which is arranged advantageously inside a lubri- cant storage chamber or collector.
