PURPOSE:To provide the subject device wherein gas supply and exhaust ports are provided in heat accumulators of a hot gas reciprocating machine, whereby pressure control is facilitated by a compact organization. CONSTITUTION:Gas supply and exhaust ports 50a through 50d are provided at heat accumulators 6a through 6b, and said exhaust ports 50a through 50d are communicated with a heating vessel 2 provided in the vicinities of heaters 5a through 5d by way of fine pipes 3a through 3d and 5a through 5d. Said heating vessel 2 is communicated with a crank case 24 by means of one fine pipe 51 provided at its intermediate part with a valve 23, and further the heating vessel 2 is provided with the heating burner 1 to control the operating gas pressure. In the above described organization, exhaust ports 5a through 5d are provided in the heat accumulators 6a through 6d, whereby lowering of the work of the operating gas due to the increase in the dead capacity is reduced, and further since the exhaust ports are positioned at parts where the pressure fluctuation and average loss are small, the pressure control is facilitated. Furthermore, since there is provided neither compresser nor several valves constituting a mechanically moving part, the organization is compact. |
