As shown in fig. 1 to 3, on the basis of the above embodiment, the compressor 10 further includes a first valve body 310 and a second valve body 320, the first valve body 310 is used for controlling the conduction and the closing of the first supply passage 112, the second valve body 320 is used for controlling the conduction and the closing of the second supply passage 122, and specifically, the first valve body 310 and the second valve body 320 may be battery valves; in this embodiment, the first valve body 310 is disposed on a first pipe connecting the first supply passage 112 and the first liquid supply device, and the second valve body 320 is disposed on a second pipe connecting the second supply passage 122 and the second liquid supply device.
As shown in fig. 1, in the present embodiment, a first unloading channel 114 for unloading the first pressure driving liquid is further opened on a side wall of the first chamber 110, and a second unloading channel 124 for unloading the second pressure driving liquid is opened on a side wall of the second chamber 120. Thus, the first pressure driving liquid in the first chamber 110 is unloaded through the first unloading passage 114, thereby reducing the pressure in the first chamber 110; similarly, the second pressure driving liquid in the second chamber 120 is discharged through the second discharging passage 124, so as to reduce the pressure in the second chamber 120. On the basis of the present embodiment, the compressor 10 further includes a third valve body 330 and a fourth valve body 340, the third valve body 330 is used for controlling the conduction and the closing of the first unloading passage 114, and the fourth valve body 340 is used for controlling the conduction and the closing of the second unloading passage 124. Specifically, the third valve body 330 and the fourth valve body 340 may be battery valves; in this embodiment, the third valve body 330 is disposed on a third pipeline communicating the first unloading passage 114 with the first unloading device, and the fourth valve body 340 is disposed on a fourth pipeline communicating the second unloading passage 124 with the second unloading device, and the first unloading device and the second unloading device may be the same or different.
Specifically, the self pressure of the first pressure driving liquid and the self pressure of the second pressure driving liquid may be different, at this time, the first sliding valve 210 is driven to move by the first pressure driving liquid, the second sliding valve 220 is driven to move by the second pressure driving liquid, so that the first sliding valve 210 and the second sliding valve 220 are attached to each other, when the pressure applied to the first sliding valve 210 is different from the pressure applied to the second sliding valve 220, the first sliding valve 210 and the second sliding valve 220 move in different directions, and thus, the pressure ratio of the compressor 10 is adjusted under the full-load working condition of the compressor 10.
As shown in fig. 1 to 3, it is needless to say that the self pressure of the first pressure driving fluid and the self pressure of the second pressure driving fluid may be the same, and in this case, the pressure applied to the first spool 210 by the first pressure driving fluid in the first chamber 110 may be adjusted by opening and closing the first valve body 310 and the third valve body 330, and the pressure applied to the second spool 220 by the second pressure driving fluid in the second chamber 120 may be adjusted by opening and closing the second valve body 320 and the fourth valve body 340; when the pressure applied to the second slide valve 220 by the second pressure driving liquid in the second cavity 120 is greater than the pressure applied to the first slide valve 210 by the first pressure driving liquid in the first cavity 110, the first slide valve 210 and the second slide valve 220 move to be attached, and the first slide valve 210 and the second slide valve 220 simultaneously move in a direction of squeezing the first cavity 110, so that the pressure ratio of the compressor 10 is increased when the compressor 10 is in a full-load working condition; when the pressure applied to the second slide valve 220 by the second pressure driving liquid in the second cavity 120 is less than the pressure applied to the first slide valve 210 by the first pressure driving liquid in the first cavity 110, the first slide valve 210 and the second slide valve 220 move to be attached, and the first slide valve 210 and the second slide valve 220 simultaneously move in a direction of squeezing the second cavity 120, so that the pressure ratio of the compressor 10 can be reduced when the compressor 10 is in a full-load condition.
Further, when the first and second slide valves 210 and 220 move simultaneously while being engaged, the third valve body 330 is opened to unload the pressure in the first chamber 110, and at this time, the first and second slide valves 210 and 220 can move synchronously to the outlet position of the first unloading passage 114, so that the compressor 10 has one pressure ratio, that is, the compressor 10 can indicate the corresponding pressure ratio by fixedly setting the outlet position of the first unloading passage 114; further, in the present embodiment, the number of the first unloading passages 114 is at least two, and the first unloading passages 114 are arranged at intervals along the moving direction of the first slide valve 210, and according to the above description and reasoning, the inlet position of each of the first unloading passages 114 corresponds to one compressor 10 pressure ratio, so that the arrangement of at least two first unloading passages 114 can correspondingly indicate the pressure ratios of two compressors, and at this time, the inlet position of the first unloading passage 114 indicates that the compressor 10 pressure ratio is at a large position, because the compressor pressure ratio gradually increases in the direction of pressing the first cavity 110.
As shown in fig. 1 to 3, similarly, in one embodiment, the number of the second unloading passages 124 of the compressor 10 is at least two, and the second unloading passages 124 are arranged at intervals along the moving direction of the second sliding valve 220, and in this case, the inlet position of each of the second unloading passages 124 corresponds to the pressure ratio of one compressor 10, so that the arrangement of at least two second unloading passages 124 can correspondingly indicate the pressure ratios of two compressors, and in this case, the inlet position of the second unloading passage 124 indicates a position where the pressure ratio of the compressor 10 is relatively low, because the pressure ratio of the compressor gradually decreases in the direction of pressing the second cavity 120.
As shown in fig. 1 to 3, further, since one end of the elastic restoring member 230 is connected to one end of the first sliding valve 210 and the other end of the elastic restoring member 230 is connected to one end of the second sliding valve 220, when the fourth valve body 340 is opened and the second valve body 320 is closed, the second chamber 120 is in a pressure relief state, the third valve body 330 is opened, the first sliding valve 210 is closed, the first chamber 110 is in a pressure relief state, the first sliding valve 210 and the second sliding valve 220 are separated by the elastic restoring member 230, and the through hole 160 formed between the first sliding valve 210 and the second sliding valve 220 is gradually increased, so as to adjust the flow rate of the compressor 10.
