Abstract

617,382. Fluid-pressure servomotor-control systems. JENNINGS, H. W. K. (Petersen, K. N. M.). Sept. 27, 1946, No. 28976. [Class 135] [Also in Groups X and XXXV] A fluid-pressure servomotor controls the air flow in a ventilation channel 1 (see-Group X) in accordance with both the pressure in the channel and the outdoor temperature. A pressureresponsive feeler 5 acts on bollows 7 to open a throttle 6 mounted on a pivoted arm 13 at the end of a pressure line 14. This causes fluid to escape from a regulator 10, thus moving a valve 11 in the channel, through levers 23, 24, to alter the air flow and thus restore the pressure balance. Bellows 8 connected to a temperature sensitive member 9 also moves the arm 13 to open the throttle 6, the balance being restored as before. The regulator 10 may vary the speed of the blower 3 or adjust the blades thereof instead of moving a valve. Additional temperature-sensitive members may be provided.
