排气管出气口、换向气管出气口、正向气管出气口、反向气管出气口均设置在换向阀体上。
在增压气缸盖上设置有用于将所述加压气管第一出气口与高压气管接头导通的减压阀，在所述阀座上设置有用于将所述换向气管出气口与换向气管进气口导通的增压阀。
多级增压装置为三级，包括一级气缸31、二级气缸33以及三级气缸35，在 一级气缸31内设置有一级活塞32。二级气缸33连接在一级活塞31上，在二级气缸33内设置有二级活塞34。三级气缸35连接在二级活塞34上，在三级气缸35内设置有三级活塞36。
正向气管进气口121与正向气管出气口采用正向气管65连接，高压气管第一出气口122和高压气管第二出气口132采用加压气管62连接在高压气管接头53上，反向气管进气口131与反向气管出气口采用反向气管66连接，换向气管进气口133与换向气管出气口采用换向气管64连接。
如图3所示，在图2的基础上增加了气体增压往返控制器9的连接，气体输入接头8与自动气控开关装置进气口相通，高压气管出气口与过滤器相通。高压气体进入过滤器腔41。空气中的水被过滤腔过滤，滴入储水腔42内，过滤后的气体通过出气口输出到容器中。储水腔42的积水达到一定的量时，打开泄气排水阀43，积水从排气口跟气体一起排出。
换向气缸控制装置100可以通过压力调节螺栓102来设定一预定气压，过滤后气体通过出气口输出到腔体，当腔体内的压力达到设定压力时，气体自动打开换向阀门101。
气体进入动力气缸206，把多级活塞杆202向上推，关闭阀门，多级活塞杆202推到顶部时气体通过减压孔205排出。压力排除后换向阀门101自动关闭。气体低于设定压力时，按下开关按钮打开阀门，两位两通气缸座203将开关卡在固定位置。
