Humidity control system and humidity responsive control device therefor

摘要

A fluid control system being responsive to humidity conditions as sensed by a humidity responsive control device that controls a fluid bleed means of the control system in response to humidity conditions sensed thereby, the humidity responsive control device having a flapper spring lever pivotally carried by a frame in a cantilevered manner and having a free end controlling a bleed valve seat. The flapper spring lever has a normal bias to tend to move the flapper end to one of its pivoted positions relative to the valve seat and is operatively associated with an actuating lever by a spring means, the actuating lever being controlled by a humidity sensing means.
