.~.~ And fluid pressure responsive flow modifying means
DEFINITION
Classification: 239/464
(under subclass 463) Apparatus in which there is also provided a means for adjusting, controlling, regulating or altering the flow of fluid, which means is responsive to pressure of a fluid.
(1) Note. The flow modifying means must control the flow to the egress opening in accordance with the fluid pressure. A mere check valve or other similar on-off valve member does not qualify for this subclass unless the check valve opens paths in addition to those already passing fluid.
SEE OR SEARCH THIS CLASS, SUBCLASS:
452+, for a distributor in which the outlet is formed between parts mounted for relative motion and having a discharge modifier or control actuated by a means responsive to the pressure of the fluid.
533+, for fluid pressure responsive discharge modifiers or flow regulators not associated with whirling devices.
