FREE PISTON TYPE STIRLING GENERATOR

摘要

PURPOSE:To make compact the structure and to improve the efficiency of the titled device by a construction wherein relative movement of a power piston and a displacer piston is ensured by a magnetic force of an electromagnet. CONSTITUTION:A stator coil 14 is provided on the side of a cylinder 3 opposite to a gnerating magnet 2 of a power piston 1. The power piston 1 includes an electromagnet 19 which is intermittently excited by a part of an electromotive force caused by the stator coil 14. A magnetic substance 20 is buried in a displacer piston 4 in an opposite relation to the electromagnet 19. An AC electromotive force due to reciprocal movement of the power piston 1 causes the electromagnet 19 whose magnetic force in turn reciprocates the displacer piston 4.
