Variable rate flow controller.

摘要

The rate at which a flow control valve (10) maintains flow under varying pressures can be adjusted by positioning a resilient flow control washer (22) on a valve seat (18) and engaging the opposite surface of the washer (22) with an adjustable member (34) which can be moved toward and away from the valve seat (18) to compress the washer in varying amounts and thereby alter the value at which the washer maintains a constant flow.
