Embodiment
According to the figure, axle 8 is equipped with Sealing 6 and bearing 7 by both sides end cap 4, gland 5, forms compression cylinder 1 and the work-doing cylinder 2 in annulus chamber in intermediate clapboard 3 both sides respectively;
Cam follower 0 axle in compression cylinder and work-doing cylinder is equipped with;
In intermediate clapboard, drive push rod 3.3 by push rod cam 8.1, push rod both sides are connected with intake valve 3.2 with exhaust valve 3.1 respectively, and wherein exhaust valve is located at compression cylinder side, and intake valve is located at work-doing cylinder side;
Be provided with air intlet 02 in the upper and lower both sides of compression cylinder, and telescopic baffle 03 is housed;
Be provided with waste gas row's mouth 06 and oil nozzle 05 in the upper and lower both sides of work-doing cylinder, and spark plug 04 and telescopic baffle are housed.
The chamber of compression cylinder and work-doing cylinder arranges a pair or multiple.
Multiple unit by compression cylinder and work-doing cylinder are installed on a shaft, are combined to form multicylinder engine.
Working procedure of the present invention:
Under static state, cam follower is divided into 2 chambers mutually by telescopic baffle.
Operationally, cam follower rotates two the chambeies formation volume-variation from small to large and from big to small making to be separated into by telescopic baffle, forms air-breathing and compression process, makes cam follower be transitioned into compression chamber from air aspiration cavity, complete the process of air compressing.
Along with the rotation of axle, after air compressing process completes, axle drives push rod cam to order about the intake valve that the exhaust valve being located at compression cylinder side on intermediate clapboard is conducting to work-doing cylinder, and enter in work-doing cylinder, and after compression exhaust terminates, turnover valve-closing, oil nozzle oil spout thereupon, plug ignition, makes the high-pressure air coming from compression cylinder mix with fuel oil, is lighted, generation combustible gas breaks out, actuating cam rotor rotates work done, and when cam follower runs to waste gas outlet position, waste gas is discharged outside body.
Feature of the present invention:
1, because the compression of coaxial two-cylinder compound cam rotary engine, work done are circumference rotary motions, not reciprocal or curvilinear motion, decreases power loss, improves efficiency.
2, be symmetrical work done during same work done cam follower work done, decrease vibrations.
3, often rotating a circle can work done more than twice, improves specific power, can reduce the volume and weight under equal-wattage.
4, by compression cylinder and the work-doing cylinder combination of series connection many groups out of phase on the same axis, the generation of continuous and stable different capacity is realized, to be applicable to the application of various working condition dynamic power machine.
