Description

The engine essentially consists of three important parts:

Head plate (1) engine block (2) oil pan (3).

The lifting shaft (5), which actuates the valves (6) in the generally known manner, lies on the uppermost surface of the top plate in two opposite bearings.

In the engine block (2) there is a partition that separates the upper and lower parts from each other. In the upper part is the cylinder, which is distributed over the explosion chambers (8) by means of a bolt (7). A shaft (9) goes through the middle of the cylinder. The top end of the shaft is in the bearing, which is inserted in the middle of the head plate. The piston (10) is mounted below the top plate. The wings of the piston expand in the explosion chambers (8). The explosion chambers are sealed from one another by sealing inserts (11) which are inserted in the piston wing and bolt (7).

The spark plugs (12) lead through the wall of the engine block into the explosion chambers. The shaft (9) ends in the lower part of the engine block, on which a bevel gear (13) with two rows of teeth is mounted separated by gaps.

The engine works as follows: The explosive mixture formed outside the cylinder is brought into the explosion chamber via a channel (18) which leads through the bolt (7), where the mixture is compressed by the action of the oscillating piston wing and by a controlled ignition device burns, etc.

Because the piston with the driving bevel gear (13) is mounted on the common shaft (9), both parts make equal pendulum movements. Under the center of the driving bevel gear (13) is the main shaft (14) with the driven bevel gears (15), (16), both of which are only toothed on one side. In the middle between the two gears (15 and 16) the shaft is machined spherically. A groove (17) runs all around on the spherical surface. The size of the pendulum movement (piston (10) and driving gear (13)), teeth of the driving gear (13) and the driven gears (15-16) and the movement of the groove (17) are dependent on each other. Namely: when the last teeth of the left row of teeth drift. Gear (13) and the row of teeth of the driven gear (15) move away from each other, the first teeth of the right row of teeth of the drift are already engaging. Gear (13) and the row of teeth of the driven gear (16) into one another, the explosion takes place at the same moment. The driving gear (13) then pushes back in the opposite direction; as a result, the main shaft (14) rotates via the gearwheels (15-16) in the same direction and transmits the explosion effect to the flywheel.

The smooth correspondence of the teeth from the drift. Gear (13) and that of the driven gear (16) is controlled by groove (17) in which the two arms (19) of the driving gear (13) run.

The controlled ignition device, the movement of the valves, etc., as well as what has already been mentioned, all go together.

The walls of the explosion chambers and the gears are lubricated through the oil channels (20), which lead through the shaft (9). The cooling can be solved either with water or with air.

The lower part of the engine block is closed by the oil pan (3).

The pendulum piston rotary internal combustion engine is characterized by the fact that its construction: a) explosion rooms, b) the pendulum piston, c) the solution of the engine should be placed under protection as new.
