Rotary Heat Engine
The invention concerns the rotary toroidal heat engine thought to equip motor vehicle, aircrafts, ships, drive electric generator set, drive pumps and compressors; when using steam power, it may be used for driving electric generator sets.
The conventional heat engines used at present, may not entirely take over the force generated by the expansion as the pistons convey this force by a connecting rod and crankshaft. The maximum force sent to the crankshaft by the connecting rod is reached when there is a maximum force momentum between the connecting rod and the crankshaft, but this occur only for a short term.
The usual rotary heat engines, for this case Wankel engine, do not take over the entire force resulting from expansion because of the shape of the rotary piston and combustion chamber.
This invention solve the aforesaid problems by using a toroidal combustion chamber provided with inlet and outlet windows for the suction of the air and discharge of burnt gases; here two pairs of semitorodial pistons spin, one of them being fix on the crankshaft by a supporting disk ; they also provide the fuel supply; and a pair of pistons that may spin on the crankshaft by their supporting disk which block themselves at the moment of the ignition by the aid of a blocking system. Thus, the entire force resulting from expansion is taken over by the driving axle, the spinning force momentum being maximum permanently - the force arm is perpendicular to the force direction in any moment.
No rotary engines with a design close to the invention are known. There shall be presented some engine solutions considered the most related ones.
Heat engines with inner combustion transforming the translation movement of the pistons in spinning movement of the crankshaft have a poor efficiency due to the design of the mechanical components, materials used in construction and operating principle. The heat engines with inner combustion and linear stroke of pistons are highly polluting; the volume of the combustion chamber is constant, the production cost is expensive, have a reduced reliability due to a large number of moving elements causing large wears
because of the frictions.

- continuously taking over of the force resulting from expansion with a maximum force momentum in the conditions in which a variation of the combustion and inlet chamber volume is possible.

Operating principle
The operating principle refers to a single toroidal motor assembly, the rotary heat engine with swinging pistons, as per the invention, has in its structure four toroidal motor assemblies.
The operating principle refers to the sequence figures S1A,B - S21A,B which represent the frontal views of the ring surface where the discharge block (5) is viewed, the fixed pistons on the engine shaft (13), the swinging pistons (25) on the engine shaft for the sequences A and inlet block (41), the command rolls, the control lamellas (63, 64) for the sequences B for normal operating conditions and at the sequence figures S1 A',B! - S21 A', B' which represent the frontal views of the ring surface, where the discharge block (5) is viewed for sequences A', the fixed pistons on the engine shaft (13), the swinging pistons on the engine shaft (25) and for sequences B' - the inlet block (41), the command rolls, the control lamellas (63, 64) for maximum operating conditions:
Normal operating conditions:
Starting: the rotary heat engine of toroidal type with swinging pistons is started by means of two starting devices, which rotate the force axles (98, 99) in bevel gearing with the engine shaft (121 , 122). The air passing through the air filter (1) is pressurized by the air admission turbine (2) inside the admission chamber determined by the gripping cylinder and the conical admission cylinder of the engine case (102). This pressurization determines the entrance of the fresh admission air by means of external admission windows of the inlet block (41, 42, 43, 44). This air is forced to wash the exterior of the inlet block (41, 42, 43, 44), being guided by an obstructing device which blocks the air access to the admission window internal to the inlet block from the vicinity of the admission hole on the rim, which makes the fresh air to get into the pistons toroidal chamber by the internal admission window positioned contrary to the admission window on the external rim. The fresh air washes the toroidal chamber by the back of the swinging piston and by the front of the fixed piston. The air comes out by the evacuation window of the toroidal chamber and washes the exterior of the discharge block being forced by the separation element from the vicinity of the evacuation window. The air goes out by the rim positioned contrary to the evacuation window, in the evacuation area determined by the conical cylinder of admission and the external cylinder, by means of evacuation channels form the engine case (102), without having contact to the admission fresh air. Depressurization created by the evacuation turbine (100) makes the air to be absorbed by means of the conical chamber of evacuation formed by the walls of the admission cone and of the external cylinder of the engine, being passed into the atmosphere by the catalyst filter. This process takes place so long as the internal admission and evacuation widows are not obstructed by the fixed and swinging pistons. From the air quantity which enters 80% is used for cooling and washing and 20% for combustion.
Fuel supply is gravitationally made by the fuel admission channels, the supply pressure being raised by the spiral disks fixed by the engine shaft, and then by means of the fuel channels inside the engine shaft the fuel reaches the disks supporting the fixed pistons, where the supply pressure is again increased and to the injection systems from the fixed pistons on the engine axle. The fuel injection is made behind the fixed piston on the engine
shaft.
