Next, we take an outer cylinder ring, an inner cylinder and two cylinders on the same circle surrounded by two cylinder head sets (as shown in Figs. 36 and 37) as an example to carry out the working principle of the present invention as an internal combustion engine. Description:

In the first stage, when the left piston 3 (hereinafter referred to as the left piston) swings downward (counterclockwise) in the left cylinder 10, the right piston 3 swings upward (also counterclockwise) in the right cylinder 10 to make the left cylinder 10 The volume located above the left piston 3 (hereinafter referred to as the upper left cylinder) gradually becomes larger. The volume of the left cylinder 10 below the left piston 3 (hereinafter referred to as the lower left cylinder) gradually becomes smaller and the right cylinder 10 is located at the right piston. 3 The volume below (hereinafter referred to as the lower right cylinder) gradually becomes larger. The volume of the right cylinder 10 above the right piston 3 (hereinafter referred to as the upper right cylinder) gradually becomes smaller, under the action of the gas distribution system: the upper end of the left cylinder 10 The intake valve opens to close the exhaust valve, and the upper left cylinder performs an intake stroke; the intake valve at the lower end of the left cylinder 10 closes the exhaust valve to open, the lower left cylinder performs an exhaust stroke; and the intake valve at the lower end of the right cylinder 10 opens the exhaust valve. The valve is closed, and the lower right cylinder performs an intake stroke; the intake valve at the upper end of the right cylinder 10 closes the exhaust valve, and the upper right cylinder performs an exhaust stroke.

In the second stage, after the completion of the first stage, when the left piston 3 swings upward (clockwise) in the left cylinder 10, the right piston 3 swings downward (also clockwise) in the right cylinder 10, in the gas distribution system. Under the action: the intake valve and the exhaust valve at the upper end of the left cylinder 10 are closed, and the upper left cylinder performs the compression stroke: the intake valve at the lower end of the left cylinder 10 opens the exhaust valve to close, and the lower left cylinder performs the intake stroke; The intake and exhaust valves at the lower end of the cylinder 10 are closed, and the lower right cylinder performs a compression stroke; the intake valve at the upper end of the right cylinder 10 opens the exhaust valve to close, and the upper right cylinder performs an intake stroke.

In the third stage, after the completion of the second stage, when the left piston 3 swings downward (counterclockwise) in the left cylinder 10, the right piston 3 swings upward (also counterclockwise) in the right cylinder 10, in the gas distribution system. Under the action: the intake valve and the exhaust valve at the upper end of the left cylinder 10 are closed, and the left upper cylinder performs the power stroke: the intake valve and the exhaust valve at the lower end of the left cylinder 10 are closed, and the lower left cylinder performs the compression stroke; The intake and exhaust valves at the lower end of the cylinder 10 are closed, and the right lower cylinder performs a power stroke; the intake and exhaust valves at the upper end of the right cylinder 10 are closed, and the upper right cylinder is subjected to a compression stroke.

In the fourth stage, after the completion of the third stage, when the left piston 3 swings upward (clockwise) in the left cylinder 10, the right piston 3 swings downward (also clockwise) in the right cylinder 10, in the gas distribution system.

When such a cycle is completed, the main shaft 54 rotates two times, and each piston 3 swings back and forth for two rounds. Because each piston 3 has two upper and lower working faces, each working face completes one work, so each piston 3 works twice in one cycle, and two pistons work four times. The reciprocating oscillation of the piston 3 drives the reciprocating rotation of the inner cylinder block 2 and the cylinder shaft 5, and then the rotation of the main shaft 54 is driven by the components such as the wobble plate 51 or the swing shaft 21, the link 52, and the crankshaft 53 to output kinetic energy.

Of course, if it is used as a compressor, the working principle of the person skilled in the art can be understood, and details are not described herein.
