.~ Plural separate sensing means for a single fluid controller
DEFINITION
Classification: 417/282
(under subclass 279) Apparatus in which the fluid flow control means comprises a single flow controlling element for a single fluid passage controlled by a plurality of separate sensing elements or signals, each responsive to a different condition or change in such condition.
(1) Note. A bypass valve provided with means responsive to discharge pressure will not be classified in this subclass merely because the valve or controller is exposed to the fluid entering the pump. Such a bypass valve is classified below on other features.
SEE OR SEARCH THIS CLASS, SUBCLASS:
300, for a flow generated pressure differential which is sensed and the high and low pressures determining such differential applied to opposite faces of an actuator controlling the fluid flow control means.
