1.快速推进阶段：在快进气缸上腔通入压缩空气，此时其下腔口连通空气，同时增压缸储油桶通过补油阀从油箱快速补油到油缸上腔，油缸下腔油液流回油箱。直到快进活塞杆接触上件，快进推力与阻力达到平衡，快进气缸停止并保压。

1. rapid propulsion stage: the compressed air is inserted into the cavity of the fast inlet cylinder. At this time, the air in the lower cavity is connected. At the same time, the oil tank of the pressurized cylinder is quickly filled from the tank to the tank of the oil tank through the oil filling valve, and the oil fluid in the lower chamber of the cylinder flows back to the tank. Until the fast piston rod contacts the upper part, the forward thrust and resistance are balanced, and the fast forward cylinder stops and keeps pressure.

2.增压过程：当快进气缸快进推力无法推进时，增压气缸A口开始向上腔通压缩空气，其活塞带动与固联在一起的增压柱塞向增压油缸伸进，其下腔B口与空气连通；同时补油阀切断增压油缸上腔与油箱，使它们不再连通；同时被油阀切断增压油缸上腔与油箱，使它们不再连通。增压油缸上腔液体处于封闭状态，随增压柱塞的伸进，其容积发生变化，容积内油液压力成比例升高，使用于液压活塞从而使增压缸输出更大的力，与快进气缸活塞一起增压工进，直到达到工作要求。

2. supercharging process: when the fast progressive thrust force of the fast inlet cylinder is unable to push forward, the A inlet of the pressurized cylinder begins to compress the air into the upper chamber, and its piston drives the pressurized plunger connected together to the pressurized cylinder, and the lower B port is connected with the air; and the filling valve cuts off the upper chamber and the tank to make them no longer connected; at the same time, the valve is not connected. The oil valve cuts off the upper chamber and the fuel tank of the supercharged cylinder so that they are no longer connected. The fluid in the turbocharged cylinder is in a closed state. With the expansion of the pressurized plunger, the volume of the fluid is changed, the oil pressure in the volume increases proportionately, which is used in the hydraulic piston to make the turbocharged cylinder output greater force and pressurized with the fast forward cylinder piston, until the work is reached.

3. 快速复位阶段：增压工进结束，在快进气缸D口和增压气缸下腔B口同时通压缩空气，两缸上腔A，C口通空气，增压气缸快速返回；同时被油阀连通增压油缸与油箱，在快进气缸活塞的带动下，增压油缸上腔排油，下腔补油直到快进气缸到位，此，气液增压缸的一个工作过程结束，下个过程程重复以上动作。

3. rapid reset stage: the supercharging work is finished, the air is compressed at the B mouth of the fast inlet cylinder D and the lower chamber of the pressurized cylinder. The upper chamber of the two cylinder is A, the C port passes air, the pressurized cylinder returns quickly; at the same time, the oil valve is connected to the turbocharged cylinder and oil tank, and the oil cylinder is added to the oil cylinder and the lower cavity is filled up under the drive of the fast inlet cylinder piston. The quick intake cylinder is in place, so that a working process of the gas liquid boosting cylinder ends and the next process repeats the above action.
