摘要:
This invention relates to a constant flow control valve comprising a main flow passage whose area is variable by fluctuation of a fluid dynamic pressure, thus permitting a constant flow rate and a by-pass passage which is mounted along an external periphery of the main flow passage, has a by-pass valve opening whose area can be varied as the area of the main flow passage is varied, and is closed and sealed, thus being made to be unusable as necessary.
