Reset Controller With Improved Input Mechanism
Reset Controller With Improved Input Mechanism
US Patent:
4394869, Jul 26, 1983
Filed:
Dec 16, 1981
Appl. No.:
6/331362
Inventors:
Gilbert H. Avery - Memphis TN
Assignee:
Barber-Colman Company - Rockford IL
International Classification:
G05D 1606
US Classification:
137 82
Abstract:
A controller for a damper maintains a substantially constant volumetric rate of flow of air through a duct into a controlled space for a given condition in the space and resets the rate of flow to three different levels as a function of three different conditions in the space. Two pneumatic actuators respond to the four conditions in the space and produce forces which vary with the conditions. A floating lever receives the forces and causes the controller to set the air flow as a function of the sum of the weighted values of the forces produced by the two actuators.
