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