In this Rankine cycle system, the rotation of the belt wheel 33 by the fluid machinery 12 shown in the Fig. 3 by means of motor, the first axle 30 rotations.If pump 1 is not killed etc., and pump torque limiter 43 transfers to sensitive axis 61 and master gear 41 by power from the first axle 30, and pump 1 is driven.Pump 1 sucks refrigeration agent and discharges this refrigeration agent from the first outlet 13h from the first import 13g.Therefore, refrigeration agent is supplied to boiler 3 from pump 1.In boiler 3, by pressurized air, refrigeration agent is heated.
Can from the second import 21a of decompressor 5, flow into by adding the refrigeration agent of thermal expansion, and the refrigeration agent after expanding flows out from the second outlet 19e.Therefore, make the second axle 32 along the direction rotation identical with the first axle 30.
Here, as shown in Figure 6, if the rotational speed of the second axle 32 is less than the rotational speed of the first axle 30, remain on each roller 73 in retainer 74 and will compress each and promote forward spring 77, and simultaneously due to the different of rotational speed between the first axle 30 and retainer 74 along the directions contrary with sense of rotation R relatively move (moving counterclockwise in the drawings).Correspondingly, in overrunning clutch 65, each roller 73 is positioned at respectively in each planar surface portion 720 of inner ring 72, being released by means of engaging of each roller 73 between interior all rolling surface 71a and periphery rolling surface 72a.Therefore the power transmission that, overrunning clutch 65 stops between the second axle 32 and the first axle 30.
As shown in Figure 5, when the rotational speed of the second axle 32 realizes the rotational speed that surpasses the first axle 30, each roller 73 in overrunning clutch 65 along the direction identical with sense of rotation R relatively move (motion clockwise in the drawings).Correspondingly, in overrunning clutch 65, each roller 73 is positioned at respectively on the sidepiece of each corner part 721 of inner ring 72, and is engaged with between outer ring 71 and inner ring 72.Therefore, interior all rolling surface 71a and periphery rolling surface 72a engage by each roller 73.Correspondingly, the power transmission that overrunning clutch 65 allows between the second axle 32 and the first axle 30.Then, the second axle 32 and the first axle 30 rotation integratedly by being connected directly.The rotation of the first axle 30 can be regenerated or can prepare for the generating of power generator or power facility for motor etc.The heat of the refrigeration agent of process decompressor 5 is discharged by condenser 7.In this way, in this Rankine cycle system, in cooled compressed air, can effectively utilize used heat.
When pump 1 is owing to killing etc. and when locked, pump torque limiter 43 does not transfer to sensitive axis 61 and master gear 41 by power from the first axle 30.Therefore, sensitive axis 61 is stopped the rotation, even thereby the first axle 30 when pump 1 is shut down, also will continue to rotate.In this case, sensitive axis 61 pulls to rear side along sense of rotation R by the retainer of overrunning clutch 65 74 by disc spring 63.Therefore, in overrunning clutch 65, as shown in Figure 7, even when the rotational speed of the second axle 32 is less than the rotational speed of the first axle 30, each roller still can be positioned at respectively each corner part 722 places of the rear side of inner ring 72, and is engaged with between outer ring 71 and inner ring 72.Therefore, interior all rolling surface 71a and periphery rolling surface 72a engage by each roller 73.Correspondingly, the power transmission that overrunning clutch 65 allows between the second axle 32 and the first axle 30.Then, the second axle 32 and the first axle 30 rotation integratedly by being connected directly.Therefore, by the first axle 30, power is transferred to the second axle 32 from motor, make decompressor 5 to be used as blower so that the circulation of working fluid continues.
Therefore, this Rankine cycle system can reach effect and the advantage identical with mode of execution 1.In addition,, in this Rankine cycle system, when height-low voltage difference hour, appearance does not expand the advantage of the drag losses of machine 5.With by external signal, the locking by sensing pump 1 drives the configuration of decompressor 5 to compare, in this Rankine cycle system, this simple structure and cost are low.
[mode of execution 3]
Rankine cycle system in mode of execution 3 adopts the overrunning clutch 66 shown in Fig. 8 to Figure 11.Overrunning clutch 66 comprises retainer 78 and a plurality of spring 79 that promotes backward.
To 75 and 76, be fixed to inner ring 72 with the stator of roller 73 similar numbers.Each roller 73 is stored in each stator between 75 and 76.Promoting forward spring 77 is arranged between each stator 75 and each roller 73.Promoting backward spring 79 is arranged between each roller 73 and each stator 76.Each promotes the Driving force backward that spring 79 has the rear side on the sense of rotation R that makes each roller 73 be positioned at the first axle 30 backward.This backward Driving force be configured to be weaker than the forward propulsion that promotes forward spring 77.
In retainer 18, form the next door 78a in axial direction extending with roller 73 similar numbers.Roller 73 is stored between two next door 78a.Other configurations are identical with the configuration in mode of execution 2.
In this overrunning clutch 66, if the rotational speed of the second axle 32 is less than the rotational speed of the first axle 30, each next door 78a can be due to the different of rotational speed between the first axle 30 and retainer 78 along relatively move with the direction that sense of rotation R is contrary as shown in Figure 10 (motion counterclockwise in the drawings), and compresses respectively each and promote forward spring 77.Each roller 73 moves and is positioned at respectively in each planar surface portion 720 of inner ring 72 along the direction contrary with sense of rotation R.Therefore, between interior all rolling surface 71a and periphery rolling surface 72a, by means of engaging of each roller 73, be released.Correspondingly, the power transmission that overrunning clutch 66 stops between the second axle 32 and the first axle 30.
On the other hand, as shown in Figure 9, when the rotational speed of the second axle 32 realizes the rotational speed that surpasses the first axle 30, each next door 78a relatively moves (motion clockwise in the drawings) along the direction identical with sense of rotation R in overrunning clutch 66, and presses corresponding roller 73.In this case, as mentioned above, the Driving force backward that promotes backward spring 79 is configured to be weaker than the forward propulsion that promotes forward spring 77, and each promotes spring 79 backward by corresponding roller 73 compressions.Correspondingly, each roller 73 moves and is positioned in corner part 721 places of the front side of inner ring 72 along directions identical with sense of rotation R, thereby become, is engaged with between outer ring 71 and inner ring 72.Therefore, interior all rolling surface 71a and periphery rolling surface 72a engage by each roller 73.The power transmission that overrunning clutch 66 allows between the second axle 32 and the first axle 30.
When pump 1 is owing to killing etc. and when locked, pump torque limiter 43 does not transfer to sensitive axis 61 and master gear 41 by power from the first axle 30.Therefore, sensitive axis 61 is stopped the rotation, even thereby the first axle 30 when pump 1 is shut down, still can continue rotation.In this case, sensitive axis 61 by disc spring 63 along sense of rotation R by the retainer of overrunning clutch 65 78 layback backward.Therefore, in overrunning clutch 66, as shown in figure 11, even when the rotational speed of the second axle 32 is less than the rotational speed of the first axle 30, each roller 73 also can be positioned at respectively each corner part 722 places of inner ring 72 rear sides, and is engaged with between outer ring 71 and inner ring 72.Therefore, interior all rolling surface 71a and periphery rolling surface 72a engage by each roller 73.The power transmission that overrunning clutch 66 allows between the second axle 32 and the first axle 30.Then, the second axle 32 and the first axle 30 rotation integratedly by being connected directly.Therefore, by the first axle 30, power is transferred to the second axle 32 from motor, make decompressor 5 to be used as blower so that the circulation of working fluid continues.
In this Rankine cycle system, owing to each roller 73 being stabilized between inner ring 72 and outer ring 71 by promoting forward spring 77, next door 78a and promote backward spring 79 respectively, therefore realized preferred operability in overrunning clutch 79.Other effects and advantage are identical with mode of execution 2.
[mode of execution 4]
As shown in figure 12, in the Rankine cycle system of mode of execution 4, between the second axle 32 and the first axle 30, be provided with decompressor torque limiter 69.By contrast, sensitive axis 61 and disc spring 63 are not set.Other configurations are identical with mode of execution 2.
In this Rankine cycle system, when pump 1 is owing to killing etc. and when locked, the first axle 30 continues rotation by pump torque limiter 43.In this case, even when pump 1 is shut down, as long as the second axle 32 is no more than predetermined value with respect to the moment of torsion of the first axle 30, the second axle 32 will continue rotation.Therefore, decompressor 5 can be used as blower so that the circulation of freezing mixture continues.When the second axle 32 surpasses predetermined value with respect to the moment of torsion of the first axle 30, the power transmission that decompressor torque limiter 69 stops between the second axles 32 and the first axle 30.
In this Rankine cycle system, even when decompressor 5 is owing to killing etc. and when locked, when normal running pump 1, the first axle 30 continues rotation by decompressor torque limiter 69, and the second axle 32 stops the rotation.In this case, due to pump 1 proper motion, therefore can the circulation of freezing mixture be continued by pump 1.Other effects and advantage are identical with mode of execution 2.
Although invention has been described for reference implementation mode 1 to 4, the invention is not restricted to above-mentioned mode of execution 1 to 4, and can in the scope that does not depart from protection scope of the present invention, by necessary change, be suitable for.
For example, in the housing 23 of fluid machinery 11 and 12, can between pump 1 and decompressor 5, power facility be set.
