Abstract: An energy conversion device includes a gas cylinder having a cylinder body, and a piston guided to move along a direction. The cylinder body includes an annular partition wall unit extending from a base plate and defining a piston chamber. The piston includes a plug and an annular fence unit. Clearances are formed between the plug and the partition wall unit, and between the partition wall unit and the fence unit such that the partition wall unit does not contact the plug and the fence unit. The plug, the fence unit and the partition wall unit define a surrounding chamber unit around the piston chamber. When the plug moves toward the base plate to compress gas within the piston chamber, gas within the surrounding chamber unit is also compressed to thereby establish a gas-tight seal between the plug and the partition wall unit.
