Embodiment
As shown in Figure 7, the gas working medium of compression enters a minute two-way by A hole, one tunnel promotes the direction rotation that blade expands to volume to blade 5.2 bottoms through roundlet column type cam negative camber, blade promotes by this gas pressure and rotor shaft slide plate in rotation process is subject to the thrust of the other end curved surface and the effect of straight line shell fragment and guarantee that slide plate can be against on the curved inner wall of roundlet column type cam more closely, play good seal action, and another road of pressurized gas dwindles direction rotation to another blade 5.1 bottoms promotion blades to volume through roundlet column type cam negative camber, pressurized gas acts on and on slide plate 5.1 and 5.2, respectively produces contrary torque, but slide plate 5.2 stretches out long (comparing with slide plate 5.1), active area is large, the torque producing is greater than the torque that slide plate 5.1 produces, therefore under the torque differences effect that rotor produces on corresponding slide plate, move in the direction of the clock, gas after turning to maximum element volume work done enters compound expansion cavity by the discharge of spacer hole and further expands, as shown in Figure 8, enter the gas in compound expansion space to slide plate acting principle as mentioned above, certain gas acts on and on slide plate 5.3 and 5.4, respectively produces contrary torque, but slide plate 5.4 stretches out long (comparing with slide plate 5.3), active area is large, the torque producing is greater than the torque that slide plate 5.3 produces, therefore under the torque differences effect that rotor produces on corresponding slide plate, move in the direction of the clock, finally by the gas of crossing after compound expansion, reach very low-pressure, less to till rotor acting.Then by the exhaust port on casing, discharge expansion chamber.
The casing the other end is compression end, be equipped with two of inflating ends large, the little cylinder type cam 2 ' that equates completely, 4 ', wherein roundlet column type cam 2 ' is placed in great circle column type cam 4 ', size cylinder type cam peak is mutually 180 degree, in the middle of size cylinder type cam, with spacer 3 ', separate, now two big or small cylinder type cams and inflating end size cylinder type cam is also mutually 180 degree, two curved surfaces having realized the right and left cylinder type cam are equidistant (so that slide plate can move flexibly in expansion chamber and compression chamber), rotor shaft end face and casing inner surface, greatly, spacer between roundlet column type cam negative camber and cylinder type cam has formed two compaction cavums that differ in size, and roundlet column type cam curved surface and rotor shaft end face, slide plate and spacer internal surface have formed several little secondary seal compression element volumes, and great circle column type cam curved surface and rotor shaft end face, slide plate and spacer outer surface, casing inner surface has formed several large primary seal compression element volumes.
As shown in Figure 8, under the effect of the swelling pressure, driven rotor shaft rotation, during rotor, under the thrust of curved surface and the effect of slide plate inner shrapnel at compression or inflating end great circle column type cam, the curved inner wall of the great circle column type cam of slide plate and compression end is close to, so curved inner wall of outer ring slide plate and great circle column type cam, rotor shaft rotor end-face, outer casing inner wall face and spacer 3 ' outer surface have formed four variable element volumes, rotation due to rotor, cause element volume by minimum value, to become gradually large rotating volume within a week, by maximum, diminished gradually again, until minimum, rotation along with rotor, element volume increases gradually, while communicating with suction port C, start air-breathing, air-breathing end when element volume reaches maximum, rotor continues rotation, element volume starts to dwindle, gas is compressed, when being connected with big column cam upper air-vent E, start exhaust, the gas of discharging sucks element volume with the inlet hole F of two-stage compression chamber and communicates, as shown in Figure 7, the gas of being discharged by big column cam upper air-vent E is after cooling, by roundlet column type cam F hole, sucked again, the now maximum beginning of two-stage compression chamber element volume is air-breathing, rotor continues clockwise direction and rotates, two-stage compression element volume starts to dwindle gradually, when two pole compression slide plates rotations 180 are spent, it is minimum that secondary primitive reaches, now communicate with exhaust port D, when reaching a hour exhaust, finishes element volume, when rotor continues rotation, enter pressure of inspiration(Pi) compression process next time.The gas of discharging enters external heating device, and to pressurized gas heating, the gas after heating enters inflating end again, carries out adiabatic expansion circular work next time.It is the open cycle of working medium that this rotary expansion compression engine can adopt air, also can adopt helium to do the closed cycle of working medium.
The advantage of rotary volume-variable expansion compression engine of the present invention is: this device can adopt high temperature compressed gas-powered, adopted pottery to do thermal-protective material, make well to realize adiabatic expansion, in this motor inflate compression space in whole device than great, make overall volume little, component are few, and processing is simple, adopted pottery to do material, greasy property is good, and heat energy is utilized efficiently, be used in middle temperature drive of high-pressure gas simultaneously, outlet temperature is low, can realize refrigeration, and compressor end pressurized gas is emitted heat can also provide hot water.And can adopt fuel cheap and easy to get, can utilize solar energy and biological energy source as fuel.Its exhaust pollution is few, and noise is low, and this,, for alleviating the demand of the world to high-grade energy, reduces pollution and be undoubtedly favourable.
