Match somebody with somebody.
Further, according to some embodiments of the utility model, check valve can also be set on the second air jet flow path 212
41, shown in reference picture 6 and Figure 10, check valve 41 can control gas unidirectional to be delivered to single stage compress chamber 210, that is to say, that
Gas on two air jet flow paths 212 can be flowed into single stage compress chamber 210 by check valve 41, and in single stage compress chamber 210
Gas then can not outwards be flowed by check valve 41.For can be with the single stage compress cylinder 21 of transfiguration, during cutting-out cylinder,
The pressure of single stage compress chamber 210 is high pressure, and the setting of check valve 41 causes gases at high pressure outwards not returned from single stage compress chamber 210
Stream.And when single stage compress cylinder 21 is in normal work, the second air jet flow path 212 can be with proper function, medium pressure gas
Single stage compress chamber 210 can be sprayed into by the second air jet flow path 212.
Alternatively, check valve 41 can be arranged on compression mechanism 20 either internally or externally, can be according to practical structures spirit
It is living to set.As shown in fig. 6, check valve 41 can be arranged on dividing plate 26, further, check valve 41 is formed as valve structure simultaneously
And be fixed with limiter 42 by the grade threaded fastener of screw 43, limiter 42 can limit the work of the lift of check valve 41
With avoiding check valve 41 from acting and excessive cause to be broken.
In some alternative embodiments of the present utility model, the change capacitance type of single stage compress cylinder 21 is cut into slide plate back pressure
Change, magnetic valve 44 can be set on the second air jet flow path 212, as shown in figure 11, magnetic valve 44 can control the second air jet flow path
212 break-make.Thus, the reverse cut-off of the second air jet flow path 212 can also be realized, and works as the cutting-out cylinder of single stage compress cylinder 21
When, magnetic valve 44 can make the second air jet flow path 212 be in the state disconnected, can avoid the two-way flow of gas, controlling
Can be more preferable.
Reference picture 9 is to shown in Figure 11, and according to some embodiments of the utility model, rotary compressor 100 can also wrap
Include：The outside jet loop 50 being located at outside casing 10, the second air jet flow path 212 and the first air jet flow path 241 with it is same
Outside jet loop 50 connects.A loop is shared in the outside of casing 10 thus, it is possible to realize, in the inside of compression mechanism 20
Branch is set, can so simplify external structure, convenient installation, while some costs can be saved.
Alternatively, the slide plate 25 in single stage compress chamber 210 can be constructed its position by adjusting slide plate back pressure cavity 215
Pressure is controlled.That is, the slide plate 25 in single stage compress chamber 210 no longer carries out position control by flexible member 291,
And the pressure by adjusting gas is realized.Thus, element can be not only saved, reduces compressor production cost, and in list
During level 21 release of compression cylinder, without the effect of the flexible members such as spring 291, slide plate 25 would not prop up piston 24, can keep away
Exempt from the head of slide plate 25 and the friction of piston 24, abrasion and power can be reduced.For example, as shown in figure 3, on single stage compress cylinder 21
The suction gas port connected with slide plate back pressure cavity 215 can be set, can be slided by the outlet situation control of entering of control and suck gas port
The pressure size of piece back pressure cavity 215, it is easy to control and relatively reliable to realize the adjustment of the position of slide plate 25.
As shown in figure 3, the slide plate 25 in first order compression chamber 220 and second level compression chamber 230 still can use elasticity
Element 291 carries out position control, and it is more flexible that slide plate 25 connects reliable and adjusting position.
According to some embodiments of the utility model, magnetic element 292 can be provided with compression mechanism 20, as shown in figure 3,
Magnetic element 292 can act on the slide plate 25 in single stage compress chamber 210, to be in cutting-out cylinder operating shape in single stage compress cylinder 21
Slide plate 25 is braked during state.Thus, it is possible to slide plate 25 is set more stably to be maintained at vane slot in single stage compress 21 cutting-out cylinder of cylinder
It is interior, motion is not produced because air pressure inside fluctuates, cause slide plate 25 to produce collision with piston 24 or cylinder, cause damage parts,
Improve the reliability of rotary compressor 100.
Assuming that the work discharge capacity of single stage compress cylinder 21 is V1, second level compression cylinder 22b work discharge capacity is V2, first
Level compression cylinder 22a work discharge capacity is V3, as shown in fig. 7, to keep higher efficiency, can make V2/V3=0.55-
The span of 0.95, i.e. V2 and V3 ratio is 0.55-0.95 (including two endpoint values).For example, of the present utility model
In some specific examples, V2/V3 value is respectively 0.60,0.65,0.70,0.75,0.80,0.85 etc..As shown in figure 8, it is
Keep higher efficiency, can make V1/V3=0.35-1.8, i.e. V1 and V3 ratio span for 0.35-1.8 (including
Two endpoint values).For example, in some specific examples of the present utility model, V1/V3 value is respectively 0.55,0.75,
0.95th, 1.15,1.35,1.55 etc..
For different areas and use condition, V2/V3 and the different of V1/V3 bring different efficiencies in the future, are evaporating
With the temperature difference of condensation it is big when (such as heat pump working condition), V2/V3 can be arranged to smaller value；When both temperature difference are smaller, Ke Yiqu
Higher value, and V1/V3 can improve compression function then from V2/V3 on the contrary, be so directed to different regions and different use conditions
