(5) in the middle of the sugar-preserved gourd shape triangle through hole, this hole also is two, promptly on lug one, switch (3) and switch spring (29) are kept supplying in this hole, and switch (3) and switch spring (29) also respectively are two.Follow rotor (8) and be the garden cylindricality, one crescent shape breach is arranged on the outer garden, the effect of this breach is in rotation and cam follower (11) on lug cooperate, the promising square tube hole of following rotor (8) rotary balance and cutting out that makes, the opposite of breach, in the middle of following rotor (8) hole, a garden is arranged, in this hole keyway is arranged, key and follow rotor shaft (7).Following rotor (8) is four.Rotor shell (2) is a square cylinder, screws out five holes, garden that cross one another with the bed of lying in the middle of looking from an end, and middle hole is big, four jiaos of four holes are little, the diameter in four jiaos of four holes is identical, and four jiaos of four holes are for following rotor (8) by putting, and middle macropore is pressed cam follower (11).Four jiaos of rotor shell (2) rear and front end also have four countersunk holes, and totally eight countersunk holes are kept supplying gear box A (46) and gear box B (47).Leading to inwall on the outer wall of rotor shell (2) has the hole of four little smooth through holes and four band platforms, and four small through hole are exhaust port (4), and spark-plug hole (10) is promptly gone up for pressing the hole of spark plug (9) in the hole of four band platforms.Gear box A (46) and gear box B (47) are seen as the garden box-like from appearance, and gear box A (46) and rotor shell (2) rear end join, and gear box B (47) and rotor shell (2) front end join.Cam follower end cap A (27), spacing point (28), annular sealing cover (18) are arranged on the gear box A (46), follow exteranl gear (19), cam follower gear (25) and gear-box end cap (1).Cam follower end cap A (27) is seen as convex shape from a side, from being seen as garden shape up and down, at its projection inwall bearing chamber is arranged, keep supplying bearing of compressor (30), outer wall has three countersunk holes, keeps supplying cam follower gear (25), near protruding the position two through hole is being arranged, keep supplying switch (3) and switch spring (29), its inwall has garden shape seal groove near the garden circumferential edges, and seal ring D (43) is arranged in the seal groove.Spacing point (28) has four, and spacing for switch (3), annular sealing cover (18) is the garden cast, and five equilibrium has four to wear the hole of following rotor shaft (7) on its circle width of cloth.Follow commentaries on classics gear (19) and be common garden gear, four such gears are arranged in the gear box A (46), promptly follow such gear is arranged on the rotor shaft (7) interior one of gear box A (46), cam follower gear (25) also is a common garden gear, but three people's small through hole are arranged, on its spoke for connecting cam follower end cap A (27) by screw B (23).Gear-box end cap (1) is the garden female cap, cover five bigger through holes, the nineteen small through hole, five bigger through holes are bearing chamber, following in the bearing chamber on rotor bearing (20) and output bearing (24) bearing chamber has bearing cap A (21) and bearing cap B (26).Parts and the parts in the gear box A (46) in the gear box B (47) are basic identical, difference is many two carrier gears (39), it is intake duct (37) that two holes are arranged on cam follower end cap B (38) inwall, the through hole that a band platform is arranged in the middle of this covers, be bearing chamber and wear axis hole, do not go up the through hole of switch.Compressor drum gear (31) and cam follower gear (25) difference are the hole and the screws of not tightening up a screw on its spoke, and compressor shaft inlet hole (36) is arranged in the compressor shaft (35).Carburetor (48) and air-strainer (49) are not describing in detail for now using parts.

Working principle of the present invention is:

1, air-breathing: outer power drives compressor drum (13), moving plate of two symmetries (12) rotates half cycle along cam follower (11) inwall on it, make delivery air chamber (16) form vacuum chamber, fresh air becomes mixed gas by air-strainer (49) and Carburetor (48), again by compressor shaft inlet hole (36), intake duct (37), enter delivery air chamber (16) through cam follower inlet hole (51), compressor drum (13) turns to lower half, and two symmetrical moving plates (12) compress mixed gas.These pressurized gas are by the switch (3) on the cam follower (11), under the effect of (2) four spacing points of rotor shell (28), switch (3) leaves to spacing point (28), close from spacing point (28), pressurized gas are through high pressure admission hole (5), all enter firing chamber (6), two symmetrical moving plates (12) back side becomes vacuum chamber to delivery air chamber (16) again simultaneously.And extraneous gas is by air-strainer (49), Carburetor (48), compressor shaft inlet hole (36), intake duct (37), cam follower inlet hole (51) inspiration two symmetrical delivery air chambers (18), that is to say air-breathing and air compression is carried out simultaneously.

2, outburst: mixed high-voltage gas enters firing chamber (6), light by ignition mechanism and spark plug (9), produce high temperature and high pressure gas, the expansion of this gas all acts on a side of cam follower (11) lug, the component loss is very little, rotates in order to actuating cam rotor (11).Lighting for the first time after working procedure finishes, is to light working procedure for the second time with that, and it is identical to light and light for the first time working procedure for the second time, and simultaneously the waste gas of lighting for the first time by all discharges of four exhaust ports (4) on the rotor shell (2).This machine is the symmetry outburst, and symmetrical exhaust is simultaneously worked, the one side exhaust, and outburst is carried out simultaneously with exhaust.

3, transmission: cam follower (11) rotates, driving cam follower end cap A (27) rotates, cam follower gear (25) rotates, four of this gear drivens are followed exteranl gear A (19) and four and are followed exteranl gear B (41) and rotate, thereby follow rotor shaft (7) and rotate, this drives four and follows rotor (8) rotation.Follow rotor (8), cam follower (11) and rotor shell (2) and form four firing chambers (6), pressurized gas enter the symmetry igniting of two symmetrical firing chambers (6), and driving cam rotor (11) rotates, and drives output shaft (53) and rotates outputting power.Follow exteranl gear B (41) for four and rotate idler (39) rotation that drives two symmetries.Two idlers (39) rotate, and drive compressor drum gear (31) counter-rotation, thereby drive compressor drum (13) counter-rotation.Compressor drum (13) and cam follower (11) switched in opposite, two moving plates (12) are rotated along two delivery air chambers (16) inwall, and pressurized gas is simultaneously air-breathing again, carries out the circulation second time, circulation is gone down like this, and motor will gyrate by design direction.The compression rotor of motor (13), cam follower (11), follow rotor (8) and in rotation, see as roller bearing, so be called the bearing type rotary engine from integral body.
