Abstract: A motion transmitting mechanism for heat engines, refrigerating machines and heat pumps which are hermetically sealed or provided with rotary shaft seals and have reciprocating pistons connected to the motion transmitting mechanism (11) by means of connecting rods (33, 34, 23, 24), is provided with two counterrotating crank systems which are centered along a single center line, whereby the lateral forces of the pistons counteract each other so as to be eliminated and allow the use of permanent grease-lubricated and sealed rolling bearings (22, 25, 26, 35, 36).

Abstract: A heat engine has one or more reciprocating pistons, an effect-receiving device for directly receiving the useful effect from the piston or pistons without any intermediary rotating effect-transmitting mechanism, and a synchronizing device for synchonizing the movements of the piston or pistons with the thermodynamic cycle.

Abstract: In a method for supplying heat to an engine for external heat supply, the combustion of fuel and combustion air takes place intermittently in a combustor. The combustor has a valve system for supplying the combustion air, an injection system for supplying the fuel, a heater for supplying heat to the engine, and an exhaust system for the emission of exhaust gases. The valve system is disposed before the fuel injection system, while a turbolator is disposed between the fuel injection system and the heater for mixing the fuel with the combustion air. The heater is so disposed in the combustor that the intermittent motion of the combustion gases is not interfered with. The engine for carrying out this method is so designed that the valve system is disposed before the fuel injection system and that a turbolator is disposed between the fuel injection system and the heater for mixing fuel and combustion air.
