Abstract

The utility model relates to a swing piston type engine. The left end of a crank shaft is provided with a gear which is engaged with a gear on a cam shaft, and the right end of the crank shaft is provided with a flywheel. A connecting rod is arranged on the crank shaft and is connected with a swing rod, and an air hole is arranged on a cylinder body which is provided with an air valve. A swing piston is arranged on a spline shaft, and the cylinder body is divided into an A, a B, a C and a D cylinders whose sizes follow the swing angle of the piston to be changed. The utility model orderly accomplishes applying work, exhaust, air admission, compression, etc. The utility model has small structure and high efficiency.

Description

Oscillating piston engine

The utility model relates to a kind of oscillating piston engine, belongs to the technical field of motor.

The technical development of motor spreads all over a lot of fields rapidly, and its piston all is to-and-fro motion, and working principle is also roughly similar; Though the innovation of rotary engine was arranged afterwards,,, waits further to improve and development if compete with reciprocating piston because technologic restriction is not tending towards improving the status as yet.

The purpose of this utility model is that a kind of oscillating piston engine will be provided, and it can remedy above-mentioned deficiency.Adopt the oscillating-piston of swing several angle, thereby make the actions such as realizing exhaust, air inlet, compression, acting that changes of cylinder body volume; Its structure is little, the efficient height.

The purpose of this utility model is achieved in that bent axle (1) is bearing in above the crankshaft support frame (14), and the right-hand member of bent axle (1) is equipped with a flywheel (11); Bent axle (1) is gone up and is connected a connecting rod (2), and the other end of connecting rod (2) is connected in fork (3); Fork (3) axle is connected with an oscillating-piston (12); Bent axle (1) left end has gear (16) engagement on a gear (5) and the camshaft (4); Camshaft (4) is supported between left end cap (6) and the right end cap (7), and inlet hole (8) and exhaust port (9) are arranged in the firing chamber (17) between left and right end cap (6) and (7), and spark plug (10) is contained between inlet hole (8) and the exhaust port (9).Valve port (22) is set on the cylinder body (13), valve (15) is housed in the hole, oscillating-piston (12) is in cylinder body (13).

Now in conjunction with the accompanying drawings the structure of oscillating piston engine is described in detail:

By Fig. 1, bent axle (1) is bearing in above the crankshaft support frame (14), and the right-hand member of bent axle (1) is equipped with a flywheel (11); Bent axle (1) is gone up and is connected a connecting rod (2), and the other end of connecting rod (2) is connected in fork (3); Fork (3) axle is connected with an oscillating-piston (12); Bent axle (1) left end has gear (16) engagement on a gear (5) and the camshaft (4); Camshaft (4) is supported between left end cap (6) and the right end cap (7), and inlet hole (8) and exhaust port (9) are arranged in the firing chamber (17) between left and right end cap (6) and (7), and spark plug (10) is contained between inlet hole (8) and the exhaust port (9).This structure is the setting type of symmetry.

By Fig. 2, valve (15) is housed on the cylinder body (13), oscillating-piston (12) is separated into A, B, four cylinders of C, D (18,19,20,21) to cylinder body (13), the angle that oscillating-piston (12) swing is certain.

By Fig. 3, valve port (22) is set on the cylinder body (13), valve (15) is housed in the hole.

By Fig. 4, be configured between left and right end cap (6) and (7), exhaust port (8) and (9).

By Fig. 5,6, oscillating-piston (12) is contained in right-hand member, and the axle (24) of spline (23) is arranged.

This motor can be made forms such as four cylinders, six cylinders, eight cylinders, twelve-cylinder, and existing is that example is illustrated its structure and working principle with four cylinder structures: oscillating-piston (12) can be cylinder body (13) in) swing certain angle.During swing, A, B, four spaces of C, D (18,19,20,21) change its size thereupon; Four cylinder actings successively in turn, exhaust, air-breathing, compression, oscillating-piston (12) swing, driving fork (3) swings together, by the cooperation of connecting bar and crankshaft, the circle that the swing of piston is converted into bent axle rotates and outputting power, and its principle is also the same with conventional engine.

Compared with prior art, oscillating piston engine has following advantages:

1. simple in structure, volume is little.

2. bent axle and cam be apart from weak point, and the simple and camshaft of driving mechanism directly drives valve, and the valve reciprocation mass is little, easily at a high speed.

3. compare with reciprocating piston type, same cylinder number, oscillating-piston lacks than reciprocating piston, and crankshaft-link rod is also few.

4. be to swing back and forth around axle owing to piston, cylinder is not easy to wear, and is easy to sealing.

5. the commentaries on classics that outputs to fork by the oscillating-piston axle can reduce unnecessary mechanical friction, because cylinder acting, compression, exhaust and air-breathing are arranged in four cylinders simultaneously apart from being used for promoting crankshaft rotating entirely.
