A possible cylinder head 2 is shown. The two components 3a, 3b, when assembled together, give a cavity 4, half of which is shown in FIG.

The cavity 4 has a radial symmetry within the cylinder head 2 and is contoured to accommodate the rotor 5 rotating freely within the cavity with an airtight seal by its walls. The rotor 5 includes a shaft 6 having a pair of concentric drum shafts, 8. Each drum 7.8 has two parallel planes 13 of the sphere.
1.132, the parallel planes 131.132 are located symmetrically around the center of the sphere, and the intersection between the planes and the spherical section 130 is rounded off. . Furthermore, the drums 7.8 are spaced parallel to each other with respect to the plane and are separated by a thick shaft section 9 of the shaft 6.

When the cylinder head is assembled, it is damped by seals 15. The drum 7.80 spherical part is damped during rotation by the seal 15 in a manner similar to a ball bearing rotating on a similar seal.

The seal 15 is therefore placed against the spherical part so that it rotates slowly in a plane perpendicular to the plane of rotation of the drum, in order to enable even wear of the drum during rotation of the drum 7.8.

A typical ignition f-lag 20 (shown as a dotted line in FIG. 3) is
Cylinder head component 3aK is retained. The cylinder head components 3a, 3b are assembled together with the rotor 5 as shown, and installed on the top of a conventional cylinder in a conventional cylinder block 10 at a predetermined position. The entire assembly is held together by head poles 18 in the usual manner.

It will be appreciated that the recess 7& (see FIG. 3) provides an uninterrupted conduit between the carburetor and the cylinder 1a when the rotor 5 is in the position shown in FIG. This represents the intake stroke of the piston and is equivalent to the opening of a normal engine inlet spring valve. Following the intake stroke (indicated by arrow 300), rotor 5 continues to rotate and thus passage 1113& is closed. The compression stroke continues and the rotor continues to rotate, passing through passage 1.
3.18& even has a closed trench. Passage i↓, 13a is closed during the exhaust stroke and the cycle is
It repeats itself again at the beginning of the inhalation stroke.

Therefore, one revolution of the rotor 5 occurs every four strokes of the piston of a four-stroke engine.

A similar event occurs with respect to recess 8&, except that recess 8a provides a continuous conduit between passages 12.12a for the exhaust gas during the exhaust stroke. Due to the arrangement of the recesses relative to each other, at least one conduit is provided for every half revolution of the rotor 5. .
