Abstract (en)

[origin: WO0138706A1] A free-piston engine is disclosed, whose engine piston may have a force applied, in the compression direction, by means of an hydraulic cylinder, which can, by means of a switching valve, be connected to the pressure in a high pressure storage device or a low pressure storage device. According to the invention, a valve arrangement, with a control piston, is arranged between the hydraulic cylinder and the switching valve, whose control surface controls a connection with the high pressure reservoir device.
