Thereby just in time being communicated with to constitute with suction port 79 and connecting port 81 by eccentric axial portion 49,50 about Rotate 180 ° suction ports 79 and connecting port 81 sends pressurized gas into timing control mechanism 83 in the expansion chamber 59.
On two cylinders 37,38 that constitute expansion mechanism 5, have exhaust port 85,85 respectively, with the exhaust port 85 of cylinder 37, be located at main bearing member 43 sides; The exhaust port 85 of cylinder 38 then is positioned at supplementary bearing member 44 sides.
The exhaust port 85 of the cylinder 37 of one side is near anechoic room 87, from anechoic room 87, be communicated with discharge tube 13 by airtight casing 1 is inner.The exhaust port 85 of the cylinder 38 of opposite side, the through hole 89 of the cylinder 37,38 by intermediate section dividing plate 39 is housed and near anechoic room 87, and be communicated with above-mentioned discharge tube 13 by airtight casing 1 is inner from anechoic room 87.
Compression mechanical part 7 is the twin-tub type, is provided with the 1st, the 2nd cylinder of separating with demarcation strip 91 93,94.1st, the 2nd cylinder 93,94 has the 2nd 95 that runs through.
Make the 2nd 95 of compressing mechanism 7 to fuse and on an axis, be supported to and rotate freely with main bearing member 99 and supplementary bearing member 101 simultaneously by coupling 97 the 1st 41 with expansion mechanism portion 5.Have the eccentric axial portion 103,104 that is arranged on corresponding to each cylinder 93,94 for the 2nd 95, chimeric with the rotating shaft 105,106 that is configured in the cylinder 93,94 respectively.By means of the rotation of eccentric axial portion 103,104, each roller 105,106 generation phase difference is 180 ° off-centre rotation.
Exhaust port 113,114 with open and close valve 109,111 is set respectively in main bearing member 99 and supplementary bearing member 101.Exhaust port 113,114 is communicated with discharge tube 19 from each anechoic room 117,119, inner space by airtight casing 1.
As shown in Figure 3, the suction port 121 that is communicated with suction pipe 5 is set in the 1st, the 2nd cylinder 93,94, and remaining the slide plate 123 that contacts with the outer circumferential face of rotor 105,106 with compression mechanisms such as back pressure or springs, roller 105,106 and slide plate 123 constitute pressing chambers 125 and suction chambers 127.
Engage with the main bearing member 99 of compression mechanical part 7 one sides, expansion mechanism portion 5 linked into an integrated entity with compression mechanical part 7 by the supplementary bearing member 9 that makes expansion mechanism portion 5 one sides with fixing bolt 129.
Inboard in the expansion mechanism portion 5 of 7 of expansion mechanism portion 5 and compression mechanical parts is provided with not shown, the oil feed pump to expansion mechanism portion 5 with each slide part supplying lubricating oil of compression mechanical part 7; In addition, in the inside of the supplementary bearing member 101 in the outside that is in compression mechanical part 7, be provided with and bear pressurized gas by the 1st 41 thrust-bearing member 133 that acts on the thrust P1 on the 2nd 95.
According to the hydraulic mechanism 3 that as above constitutes, the pressurized gas of supplying with by suction pipe 11 after temporary transient the storage, are sent in the expansion chamber 59 from hyperbaric chamber 61 by sucking path 47 hyperbaric chamber 61 in, make the refrigeration agent of finishing after the expansion from discharge tube 13 discharges.In addition, the rotating power produced of expanding passes to the 1st 41, the 2nd 95 of portion of drive compression mechanism 7, makes each roller 105,106 do eccentric rotation, and the refrigeration agent of sending into from suction pipe 17 is compressed, discharges from discharge tube 19.In view of the above, just can obtain as shown in Figure 5 independently new bright circulation and refrigeration cycle respectively, and can best two operating conditions of setting Rankine cycle and refrigeration cycle.In addition,, thereby it is configured on the same axis accurately easily, also helps making stable performance because the distance D between each bearing of 41,95 of expansion mechanism portion 5 and compression mechanical part 7 is shorter.
In this occasion, also can the outer circumferential face of expansion mechanism 5 can complied with supplementary bearing member 9 as shown in Figure 6, the periphery of cylinder 38 that makes a side causes sealing near the internal face of airtight casing 1.
Perhaps, as shown in Figure 7, also the peripheral part of supplementary bearing member 9 can be caused sealing by make the stationary barrier 135 that is provided with in addition outside the composition member of expansion mechanism portion near the internal face of airtight casing 1.
Fig. 8 represents to make the additional embodiments of expansion mechanism portion 5 and compression mechanical part 7 separations.
Just, the outer circumferential face that is positioned at inboard main bearing member 99 in the 2nd 95 the main bearing 99 that makes swivel bearing compression mechanical part 7 and the supplementary bearing 101 causes sealing near the internal face of airtight casing 1.In addition, central side at main bearing member 99, by the sealing component 139 on the 99a of the beam barrel portion side that is installed in main bearing member 99, make the 2nd 95 the outer circumferential face sealing that extends to expansion mechanism portion 5 one sides, independently separate with compressing mechanism chamber 21 in expansion mechanism chamber 15.
In addition, other forms member because of identical with Fig. 1, represents with same label, omits its detailed description.
According to the fluid machinery 3 that as above constitutes, the pressurized gas of supplying with by suction pipe 11 are stored hyperbaric chamber 61 in temporarily after, send in the expansion chamber 59 from hyperbaric chamber 61 by sucking path 47, make the refrigeration agent of finishing after the expansion from discharge tube 13 discharges.In addition, expand and the rotating power that produces reaches the 1st 41 the 2nd 95 of portion of drive compression mechanism 7, make each roller 105,106 do eccentric rotation, the refrigeration agent of sending into from suction pipe is compressed, discharges from discharge tube 19.In view of the above, become the independently Rankine cycle and the refrigeration cycle that can obtain respectively as shown in Figure 5, and can the best operating condition of setting Rankine cycle and refrigeration cycle.In addition,, and will press the coaxial line configuration easily accurately, help stable performance because the distance D between each bearing of 41,95 of expansion mechanism portion 5 and compression mechanical part 7 is shorter.
In this occasion, the peripheral part that also can make main bearing member 99 as shown in Figure 9 reaches sealing by make the stationary barrier 141 that is provided with in addition outside the composition member of compression mechanical part near the internal face of airtight casing 1.
In sum, according to the present invention, even need not special-purpose dividing plate, independently expansion mechanism chamber and compressing mechanism chamber can be separated, best two kinds of operating conditions setting Rankine cycle and refrigeration cycle.
In addition,, accurately it is pressed coaxial line easily and dispose, and be beneficial to and make stable performance because the distance between the bearing of each of expansion mechanism portion and compression mechanical part is short.
