Working principle is following:
(1) intake stroke: as shown in Figure 3; In air inlet compression cylinder 5; Air inlet compression ratchet rotor 502 clockwise rotates with main shaft 1 synchronously, moves clockwise along circumference from top dead center, at this moment; Because being pressed in air inlet, an impeller of air inlet compression retaining ratchet 504 compresses formation sealing on the circumference external diameter a point of ratchet rotor; Another impeller of air inlet compression retaining ratchet is pressed in and forms sealing on the secondary cylinder casing wall b point, and the top end of air inlet compression ratchet rotor is pressed in and forms sealing on the air inlet compression cylinder casing wall c point, has constituted an independently sealing chamber d thus.Because air inlet this moment compression retaining ratchet is fixed, thus along with air inlet compression ratchet rotor along the clockwise rotating of circumference, independently form vacuum in the sealing chamber d, burning mixture is inhaled into into from suction port 9.Because air inlet compression ratchet rotor is pressed in the air inlet compression cylinder and does 360 ° and rotatablely move; The volume of independent sealing chamber constantly enlarges; Burning mixture constantly is inhaled into; When air inlet compression ratchet rotor rotated the arrival top dead center, burning mixture was full of in the whole air inlet compression cylinder, and intake stroke is accomplished.As shown in Figure 5.At this moment air inlet compression retaining ratchet 504 is under 8 controls of ratchet location control mechanism; Fixed after beginning to be rotated counterclockwise 90 °; Make air inlet compression ratchet rotor 502 cross air inlet compression retaining ratchet 504 simultaneously and be rotated further clockwise, come back to Fig. 3 position, and begin intake stroke the 2nd time.So constantly back and forth rotation, burning mixture is just constantly sucked in the air inlet compression cylinder.
(2) compression stroke: see Fig. 3; In air inlet compression cylinder 5; When air inlet compression ratchet rotor 502 when top dead center rotates, the direction of advance of compressing ratchet rotor in air inlet then begins to carry out compression stroke, the burning mixture that last stroke is sucked in compresses.This moment is identical with the intake stroke initial position; An impeller that is air inlet compression retaining ratchet 504 is pressed on the external diameter of air inlet compression ratchet rotor; Another impeller of air inlet compression retaining ratchet is pressed on the secondary cylinder casing wall, and the top end of air inlet compression ratchet rotor is pressed on the casing wall of air inlet compression cylinder.Rotation along with air inlet compression ratchet rotor; Constantly dwindle the space e between air inlet compression cylinder and the air inlet compression ratchet rotor; Thereby be compressed to central high pressure burning mixture, the position promptly shown in Figure 5 of forming, a very little space to the burning mixture that sucks in.This moment, air distribution hole 401 was opened; Along with air inlet compression ratchet rotor is rotated further, just the high pressure burning mixture is pressed into and prepares igniting in the work done exhaust casing 3, air distribution hole 401 is closed then; It is fixed after air inlet compression retaining ratchet begins to be rotated counterclockwise 90 °; The compression of air inlet simultaneously ratchet rotor is crossed air inlet compression retaining ratchet and is rotated further clockwise along circumference, comes back to Fig. 3 position, accomplishes compression stroke.When air inlet compression ratchet rotor when circumference continues to clockwise rotate, begin compression stroke the 2nd time, what so constantly move in circles compresses burning mixture.
Intake stroke and compression stroke are all constantly accomplished in an air inlet compression cylinder continuously, and spindle revolutions is high more, and burning mixture pressure is just big more, and temperature is also just high more, is prone to igniting.Expansion space stroke and exhaust stroke are in work done exhaust cylinder body 3, to accomplish.Between air inlet compression cylinder 5 and 3 two cylinder bodies of work done exhaust cylinder body, be connected by middle pneumatic pannel 4.The effect of the air distribution hole 401 in the middle pneumatic pannel is opened intake valve and is pressed into compressed burning mixture in the outburst cylinder in the time of appointment as the intake valve of Reciprocating engine, closes the work done of intake valve plug ignition then.
(3) work done (outburst) stroke: see Fig. 4; In the circular work done exhaust casing 301 in work done exhaust cylinder body 3; After work done exhaust ratchet rotor 302 is crossed work done exhaust retaining ratchet 304; The circumference external diameter a point that an impeller of work done exhaust retaining ratchet is pressed in work done exhaust ratchet rotor is gone up formation and is sealed; The another one impeller of work done exhaust retaining ratchet is pressed in and forms sealing secondary cylinder casing wall b point on, and the top end of work done exhaust ratchet rotor is pressed in that formation seals on the casing wall c point of work done exhaust casing, so just forms a totally enclosed firing chamber f at the intake valve place.This moment, intake valve was opened, and pressurized gas are pressed into the firing chamber, and simultaneously corresponding with the intake valve spark plug 13 that is fixed on the end cap is lighted a fire; See Fig. 7; The HTHP burning mixture that ignition combustion is indoor because work done exhaust retaining ratchet and work done exhaust casing casing wall all are fixed, rotates along circumference so expanding gas can only promote work done exhaust ratchet rotor; Work done exhaust ratchet rotor is fixed on the main shaft, so power directly is transferred to main shaft moment of rotation is directly exported.When work done exhaust ratchet rotor is pulled to top dead center near work done exhaust retaining ratchet, see Fig. 5, work done exhaust retaining ratchet begins to rotate counterclockwise 90 °, makes work done exhaust ratchet rotor cross work done exhaust retaining ratchet and sees that Fig. 3 begins the igniting of air inlet next time.So circulation is carried out again and again, and motor just produces continuous power output.
The igniting work done 1 time that rotates a circle of single ratchet rotor, the ratchet rotor of the several ratchets igniting work done that rotates a circle is time identical with the ratchet number, by that analogy.
(4) exhaust stroke: see Fig. 4, when work done exhaust ratchet rotor 302 turns to top dead center, the waste gas that once work done (outburst) stays on the direction of advance of work done exhaust ratchet rotor then is.Owing on work done exhaust cylinder body, be provided with a long outlet pipe of opening 10; When work done exhaust ratchet rotor rotates; Just promoting waste gas releases to the outlet pipe direction along circular path; When work done exhaust ratchet rotor arrival top dead center keeps off the impeller of ratchet near the work done exhaust, remain in the interior waste gas of work done exhaust casing just by whole discharges, like Fig. 6 position.At this moment work done exhaust retaining ratchet rotates 90 ° of impellers that make work done exhaust ratchet rotor cross work done exhaust retaining ratchet again, gets into exhaust stroke next time.
Common Reciprocating engine is that piston moves up and down in cylinder 4 times, affacts on the bent axle through linkage mechanism, and two weeks of crankshaft rotating (720 °) are accomplished air inlet, compression, work done (outburst), four strokes of exhaust, and work done once.And rotary engine of the present invention is in a cylinder body, to accomplish intake stroke and compression stroke; In another cylinder body, accomplish expansion space stroke and exhaust stroke; Because two interior ratchet rotors of cylinder body all are to be fixed on the same main shaft (differing several angle); Whenever the outburst work done once promotes ratchet rotor when circular path rotates a week (360 °), in two cylinder bodies, accomplished air inlet, compression, work done (outburst), 4 strokes of exhaust respectively separately, directly drive the main shaft output torque.Here it is ratchet rotor engine is than the huge superiority of Reciprocating engine.
2, in the middle pneumatic pannel, the structure of distribution device and working principle:
