Atmospheric pressure then pushes the piston back down the cylinder, and if anything (such as a pump) is attached to the piston, some useful work can be done.
于是，气压就会再次将活塞推至汽缸底部。而假如有诸如水泵这样的物体与活塞连接，就可以在活塞的带动下完成一些工作。
As altitude increases, atmospheric pressure decreases, thus exerting less "push" on the water entering the pump suction.
当海拔高度增加，大气压力减少，从而减少了作用于进入水泵的水的压力。
The compressed air system for atmospheric air, will air inhaled air compressor, after volume compressed pump into the compressed air system.
压缩空气系统的气源为大气，将空气吸入空压机中，经过体积压缩后泵入压缩空气系统。
