Gas can be divided into pneumatic gas booster pump and pneumatic liquid booster pump booster pump, they have many similarities, but there are also some differences, such as one-way valve structure are not the same, the compressibility of gas and liquid, and gas booster cylinder piston liquid booster pump plunger used.

气体增压泵在这里只对气动气体增压泵进行讨论。它的理论增压比是驱动缸活塞面积S1：增压缸活塞面积S2，实际增压比能达40：1，但是在工业应用中推荐10：1或更少的压缩比。

The gas booster pump only discusses the pneumatic gas booster pump. The theoretical supercharging ratio is the piston area of the driving cylinder S1: the piston area of the booster cylinder is S2, the actual supercharging ratio can reach 40:1, but 10:1 or less compression ratio is recommended in the industrial application.

控制阀V1和V2，换向阀V3。V3右端与V2下侧相连。当V3右端压强为0时，V3阀心在左端压缩空气P的驱动下滑到右端。此时驱动气缸上侧通入压缩空气，下侧与大气相连，大活塞受力向下运动。

Control valve V1 and V2, reversing valve V3. The right side of the V3 is connected to the underside of the V2. When the pressure at the right side of the V3 is 0, the V3 valve at the left end of the compressed air P drives down to the right end. At this time, the compressed air on the upper side of the driving cylinder is connected, and the lower side is connected with the atmosphere, and the large piston is forced downward.

虽然此时V3阀心左右端都通入了压缩空气，但是由于右端受力面积大于左端受力面积，V3阀心滑到左端。因为此时驱动气缸下侧通入压缩空气，上侧与大气相连，所以活塞向上运动。然后大活塞碰开控制阀V1，管道1就放气到0，使V3右端压强0，从而实现了循环运动。

Although the left and right sides of the V3 valve core are connected with compressed air, the V3 valve is sliding to the left end because the force area at the right end is greater than the force area at the left end. Because at this time the drive cylinder at the lower side of the compressed air, the upper side of the atmosphere connected, so the piston upward movement. Then, the large piston touches the control valve V1, the pipe 1 is deflated to 0, so that the right side of the V3 pressure is 0, so as to achieve a cycle of movement.
