As shown in Figure 1, in the prior art, during rotary slide sheet 40 ' in cylinder assembly 10 ' is because of rotary work to be guaranteed
The sliding vane groove 31 ' of the followability of slide plate, tail portion must provide certain back pressure, which is applied in cylinder by slide plate head
Frictional resistance is transferred on wall, to generate friction power loss.
According to the design feature of rotary slide sheet type compressor, the course of work is divided into inspiratory limb, compression section and exhaust section three
Stage.In inspiratory limb, slide plate head is pressure of inspiration(Pi), and tail portion is back pressure, at this time slide plate head to cylinder inner wall active force most
Greatly, and inspiratory limb slide plate with sliding vane groove is stretch out motion, and the radius of turn on slide plate head is increase process, i.e. slide plate head line
Speed is increasing, and according to W=FV, slide plate head power consumption is not only larger in expiratory phase, and is the process increased, therefore inhale
The slide plate head power consumption of gas section occupies biggish specific gravity in the whole service period.By slide plate tail end face, spring ball is set
Position limiting structure, the spring ball position limiting structure are matched with upper lower flange resigning recess portion 21, guarantee inspiratory limb slide plate head and gas
Inside wall of cylinder wide arc gap does not contact, and has obvious action to the power consumption reduced at this.
In addition, inspiratory limb slide plate two sides are pressures of inspiration(Pi), position limiting structure ensure that slide plate and cylinder inner wall wide arc gap connect
It is logical, i.e., solve suction it reduce while friction power loss without strict control inspiratory limb slide plate head and cylinder inner wall gap
The problem of air cavity inspiratory capacity deficiency, to improving, compressor cooling capacity is advantageous.
As shown in Figs. 8 to 11, compressor operation is divided into air-breathing, compression, exhaust three phases, shaft rotary course
In, vane motion is driven, to reduce slide plate head and cylinder inner wall friction power loss.Illustrate by taking slide plate 40 as an example, at slide plate 40
When the position Fig. 8, spring ball position limiting structure just starts to act on resigning recess portion 21 at this time, and slide plate 40 is in limit state；When
When slide plate 40 is in the position Fig. 9, slide plate 40 is in limit state at this time, and slide plate 40 does not stretch out, the left and right chamber connected state of slide plate 40
State shares air intake passage, is conducive to air-breathing；When slide plate 40 is in the position Figure 10, slide plate 40 is in limit state, slide plate 40 at this time
It gradually stretches out, the left and right chamber or connected state of slide plate 40, shares air intake passage, be conducive to air-breathing；When slide plate 40 is in the position Figure 11
When setting, slide plate 40 is in just at state is not limited at this time, and slide plate 40 is fully extended, and air-breathing is completed.Entire breathing process is sliding
Piece 40 is not contacted with cylinder inner wall, and there are very wide arc gaps, eliminates the friction power loss of inspiratory limb in this way, and solves suction
The problem of unsaturated vapor, to improving, compressor performance effect is obvious.
Than that described above, it is also necessary to which explanation is " one embodiment " spoken of in the present specification, " another implementation
