Based on said structure basis, below working procedure of the present utility model is described in detail.

As shown in Fig. 7 (a), during original state, a, b point of baffle plate 28 both sides is close to respectively by the first rotor 3 and the second rotor 6, and then slide laminating rotating shaft 2 outer wall in baffle plate 28 one end.The starting system of starting apparatus combustion engine, makes rotating disk 101 synchronous axial system in rotating shaft 2 and Maltese cross movement, now by external force, the first rotor 3 rotates along with the rotation of rotating shaft 2, and due to the stop of baffle plate 28, the second rotor 6 is motionless, and thus elastic device 27 is stretched.

When the first rotor 3 turns to the c point position shown in Fig. 7 (b), because the second rotor 6 is motionless, thus along with the rotation of the first rotor 3, the A district smaller volume between this first rotor 3 and second rotor 6, air is compressed.Again because the B district volume between the first rotor 3 and baffle plate 28 increases, thus the gas pressure now in this region reduces, form negative pressure, now, air outlet hole 19 is just in time communicated with curve bath 21, gas in gas holder 7 outputs in B district via tracheae 8, first inlet hole 18, first circular groove 20, curve bath 21 and air outlet hole 19 successively, and with the fuel mix of supplying via fuel supplying device 4.It should be noted that, in order to guarantee that the gas in gas holder 7 can enter in cylinder 1 further, this gas holder 7 is also provided with the first air valve 9, when the air pressure in gas holder 7 is not enough, outside air is introduced by opening the first air valve 9, just can increase the air pressure in gas holder 7, and then the gas in it is normally entered in cylinder 1.

When the first rotor 3 forwards d point to along with rotating shaft 2, due to the second rotor 6 and on the collar still motionless, air outlet hole 19 thus in rotating shaft 2 can disconnect with the curve bath 21 on the collar, and now, fuel combination is lighted by ignition mechanism 5, makes it burning.The high-temperature high-pressure fuel gas that mixture burning produces promotes the first rotor 3 and is rotated further due to expansion work, make it continue to compress the air in A district, elastic device 27 continues to be stretched simultaneously.Because air outlet hole 19 is not now communicated with curve bath 21, thus in A district by the air that compresses because air pressure is larger, thus can push the second air valve on the second inlet hole 22 open, then enter into gas holder 7 via the second inlet hole 22, first circular groove 20, first inlet hole 19 and tracheae 8 successively and store.

When the first rotor 3 turns to the e point position shown in Fig. 7 (c), the first pushing block 11 on Maltese cross movement or the second pushing block 12 just in time promote staggered form extending means and stretch, thus drive baffle plate 28 to move toward the direction away from rotating shaft 2 outer wall by fixed block, and extension spring 13, make the first rotor 3 in the effect of rotating shaft 2 rotatory force simultaneously, second rotor 6 is under the effect of elastic device 27 restoring force, (restoring force due to elastic device 27 is greater than the rotatory force of rotating shaft 2 to move to the f point shown in Fig. 7 (d) and g point respectively, thus the second rotor is faster than the rotational velocity of the first rotor).While the first rotor 3 and the second rotor 6 move to e point and f point respectively, staggered form extending means loses the active force of pushing block, thus under the effect of spring 13 restoring force, staggered form extending means is done to reclaim motion, and one end of baffle plate 28 is also moved toward the setting direction of rotating shaft 2 simultaneously, and slip fits on rotating shaft 2 outer wall again.What deserves to be explained is, in the process of baffle plate 28 movement, for ensureing the sealing in cylinder 1 further, described second one of them side of rotor 6 is arc shaped surface.So, when baffle plate 28 toward move away from rotating shaft 2 outer wall direction and the second rotor 6 moves simultaneously time, the arc shaped surface of this second rotor 6 bottom being fitted in baffle plate 28 that just can continue to slide (is equivalent to the second rotor 6 return baffle plate 28 and be applied with one toward the active force away from the direction movement of rotating shaft 2 outer wall, baffle plate 28 is made to depart from rotating shaft 2 fast), until the first rotor 3 and the second rotor 6 all move to opposite side from the side of baffle plate 28.

As shown in Fig. 7 (e), when the first rotor 3 and the second rotor 6 are respectively at f point and g point, follow-uply will carry out three flow processs simultaneously, as follows respectively:

Flow process one

Because baffle plate 28 slides laminating rotating shaft 2 outer wall again, thus when the second rotor 6 is rotated further, C district volume between second rotor 6 and baffle plate 28 can reduce, original waste gas produced after this region combustion can be compressed, make the air pressure in C district be greater than external pressure, now, outlet valve 29 is opened, waste gas just continues to discharge via outlet valve 29, and this is exhaust process.

Flow process two

Because the second rotor 6 is faster than the rotational velocity of the first rotor 3, thus the D district volume now between the first rotor 3 and the second rotor 6 can increase gradually, thus the air pressure in this region is reduced, form negative pressure, outside air enters the 3rd inlet hole 23, second circular groove 24 and the 4th inlet hole 25 successively, and the second air valve pushed open on the 4th inlet hole 25, enter in D district.

Flow process three

E district between the first rotor 3 and baffle plate 28, because baffle plate 28 is motionless, the first rotor 3 continues to rotate, thus the volume in this region can increase equally gradually, the air pressure in this region is reduced, now, because air outlet hole 19 is communicated with curve bath 21, and the second air valve on the second inlet hole 22 is closed, thus the pressurized air in gas holder 7 now just outputs in E district via tracheae 8, first inlet hole 18, first circular groove 20, curve bath 21 and air outlet hole 19 successively, and with the fuel mix of supplying via fuel supplying device 4.When the first rotor 3 forwards h point to (the second rotor 6 forwards i point to), air outlet hole 19 is not communicated with curve bath 21, and now, fuel combination is lighted by ignition mechanism 5.The high-temperature high-pressure fuel gas that mixture burning produces promotes the first rotor 3 and is rotated further due to expansion work.

As shown in Fig. 7 (f), when the second rotor 6 turns to j point, overwhelming majority waste gas is drained, now, outlet valve 29 is closed, second rotor 6 is blocked motionless by baffle plate 28, and the first rotor 3 is rotated further under combustion gas impetus, now, the volume in D district continues to reduce, until air be compressed into air pressure enough large time, the second air valve promoted on the 4th inlet hole 25 is closed, and the second air valve simultaneously pushed open on the second inlet hole 22, and then via the second inlet hole 22, first circular groove 20, first inlet hole 19 and tracheae 8 enter into gas holder 7 and store.And when the first rotor 3 turns to e point position again, the process of just can again circulate above-mentioned exhaust, air inlet, acting, compression.

All slide laminating cylinder 1 inwall in one end due to the first rotor 3 and the second rotor 6, and A, B, C, D, E district thus described in above-mentioned working procedure is closed space.According to the iterative cycles of above-mentioned working procedure, internal-combustion engine just can be made to continue output mechanical energy.

In addition, on the basis rationally extended, the utility model also can arrange multiple cylinder simultaneously, or design according to the mode shown in Fig. 8, the structure shown in Fig. 8, rotor turns half-turn can be made just to realize twice acting, thus output power is higher, and more suitable control heavy mechanical equipment runs.Therefore, permutation and combination method of the present utility model is very flexible, no matter adds macro-axis power or increases rotating speed, or lowering the center of gravity etc., and it all can perfect matching.

The utility model is by the rational modification to rotor internal-combustion engine structure, and effectively improve the power that it exports, the significantly promotion and application for rotor internal-combustion engine provide good technology place mat.The utility model can use dissimilar fuel, comprises methyl alcohol, gasoline, kerosene, rock gas and diesel oil, etc.And along with automotive fuel is from traditional fuel to the transition of alternative fuel, the utility model even can hydrogen as fuel.Therefore, compared to existing technology, the utility model technological progress is fairly obvious, and it has substantial feature and progress.

Above-described embodiment is only preferred embodiment of the present utility model; restriction not to the utility model protection domain; in every case design principle of the present utility model being adopted, and the change carried out non-creativeness work on this basis and make, all should belong within protection domain of the present utility model.
