DEFINITION
Classification: 251/53
(under subclass 48) Subject matter in which fluid is diverted from the main flow line into a tank or receiving chamber at atmospheric pressure, which is so related to the valve in the main flow line that the collection of a sufficient quantity of fluid in the tank or receiver actuates or causes the actuation of the valve.

396+, for self emptying tanks in which the main flow is controlled through the accumulation of fluid in the tank rather than the use of fluid diverted from the main flow line and subclasses 403+ for liquid level responsive or maintaining systems in which the weight of the accumulated fluid controls the accumulation thereof.
