Abstract
Disclosed is a linear expander includes: a body portion including a suction hole through which a fluid having a first pressure flows in, a discharge hole through which the fluid flows out with a second pressure that is lower than the first pressure, and first and second holes connecting an expansion space formed between the suction hole and the discharge hole, a first linear generating portion and a second linear generating portion respectively causing pistons provided in the first hole and the second hole to linearly reciprocate to generate an induced electromotive force with an expansion force generated when the fluid having the first pressure expands to the fluid having the second pressure, a suction valve opening and closing the suction hole, and a discharge valve and closing the discharge hole.
