装载机变矩器呼吸器主要是平衡装载机变矩器齿轮室内压力，正常情况下，齿轮空内只有少量的润滑油液(减压阀溢流的油液)，如内部的油液增多或存在气压，则会击溅油液到呼吸器通气孔上并溢出。这种故障一般先检查变矩器内是否有气压增高，即检查制动系统的压缩空气是否进入了行走系。
Shandong loader torque converter respirator mainly balanced converter gear loader chamber pressure, under normal circumstances, only a small amount of lubricating fluid (oil overflow valve), such as increased or presence of oil inside the gear blank pressure will splash and spill oil into the vent on the respirator. Such failures are generally first check whether there is increased pressure within the torque converter, which compressed air braking system checks whether walking into the system.

装载机由于气路与行走油路唯一沟通的地方就是变速分配阀，因此检查变速分配阀隔离杆上的“0“型圈足否损坏，方法是启动发动机，气压在o. 8-1.OMPa后熄火，倾听变速阀部位是否有漏气声，进而可打开变速箱加油口盖，检查是否有气体连续排出，如有则可判定“o"型圈损坏。如以上正常，则由于山东装载机齿轮室油液增多，一般是变矩器回油散热回路堵塞，重点检查异轮座回油路、机械油回油滤清器、机械油散热器以及其他回油管路是否堵塞。
Shandong loaders due to gas path and walking the oil is the only place where the communication speed distribution valve, so check valve isolation allocation shift lever to "0" type Quanzu No damage is to start the engine, the air pressure in the o. 8-1. OMPa after flameout, whether listening to shift parts of a valve leak sound, and then open the gearbox oil filler cap and check whether there is a continuous discharge of gas, if you can determine the "o" ring damage. As described above normal, due to the increase of oil Shandong loader gear chamber, usually back to the oil cooling loop converter plug, focus on checking different wheel seat back to asphalt, machine oil back to the oil filter, oil cooler, and other machinery back drain line is clogged.
