Rotary compressor sealing vane leakage/chatter

This video is in response to some questions by NOBOX7 and Aussie50 about a chattering noise and low flow from these rotary compressors when there is no back pressure. I took high speed video at 6000fps of the sealing vane, showing the vane separating from the rotary ring, allowing gas to escape from the high pressure side to the low pressure side.
