The invention relates to mechanical engineering, namely to connecting rod free piston machines and solves a problem of making a safe and long-lived piston machine with compact dimensions. The machine includes a body with cover plates, an output shaft (which is installed on these cover plates and interacts with gears), as well as cylinders and pistons, disposed in pairs oppositely. Pistons are provided with support washers and axial bearings, produced with necks having spherical surfaces. These surfaces interact with slots of end ring, which is located between the support washers and necks of axial bearings. Axial bearings contact with roller-pushers located in hubs of gears, which are placed in stocks of output shaft and interact with fixed cog-wheel. At the same time the body is produced in the form of a ring and a transmission ratio of gears and cog-wheel is equal to 1:2.
