A free-piston engine has an engine cylinder and a single piston member. The single piston member has a double-ended piston that moves within the cylinder, and the piston member partitions the cylinder into two separate chambers, each of which are supplied with a compressible working fluid from one or more intake means. The piston moves over and past the intake means during each stroke such that the fluid is replenished within one chamber while the piston compresses the fluid held in the other chamber. |
