Continuous flow controller, has controlling mechanisms designed for different flow rate capacities and/or pressure ranges, where one mechanism exhibits opening that acts as bypass channel, which is openable and closeable

摘要

The controller has a controller housing with a controlling mechanism (8a) including a central body (3a) in a passage channel. The mechanism encompasses a ring-shaped throttle body (4a) made of elastic material. Controlling mechanisms (8a, 8b) are designed for different flow rate capacities and/or pressure ranges. The mechanism (8b) exhibits an opening (11) that acts as a bypass channel, which is openable and closeable.
