Abstract (en)

[origin: EP3530921A1] A Stirling engine 1 includes: pistons 3 and 4 that reciprocate in a cylinder 2; a heat exchanger 7 that promotes contraction and expansion of an operating fluid in the cylinder 2; and a power takeout device 11 that converts a reciprocation driving force by each of the pistons 3 and 4 to a rotative force. The heat exchanger 7 alternately repeats contraction and expansion of the operating fluid in the cylinder 2 to cause the pistons 3 and 4 to reciprocate. The power takeout device 11 is disposed in a crank box 50 incorporated in a crankcase 13, and lubricating oil is stored in the crank box 50.
