Operation principle of the present utility model is：Checking cylinder is during alleviation, if decompression reservoir occurs being vented not freely, so that
When certain pressure air be present above adjustment valve, when checking cylinder inner air pressure is more than adjustment valve top pressure, outside
Check valve composition can also be jacked up and is exhausted, but alleviation speed is slower, can not be met that checking cylinder is alleviated and be required, and
When checking cylinder inner air pressure is no more than pressure above adjustment valve, then outer check valve can not be formed by braking in-cylinder pressure air
Jack up, and because checking cylinder alleviation is not thorough, vehicle also has band-type brake may.Now, internal check valve composition then starts to play and answered
There is effect, because internal check valve composition Opening pressure is smaller, not alleviated pressure air then can be by internal check valve in checking cylinder
The inner spool of composition jacks up, and has the function that further to be vented, so that checking cylinder occurs being vented not smooth situation in decompression reservoir
Under, can also it checking cylinder is thoroughly alleviated.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
