Abstract
A rising liquid level in a gas scrubber for an air compressor is sensed by a float in the scrubber which opens a normally closed pneumatic vent valve whereby a very small pneumatic signal is delivered through a pneumatic spool valve to the chamber of a large diaphragm liquid dump valve on the scrubber which is operated automatically to drain liquid from the scrubber to maintain a safe liquid level in the scrubber. The dump valve mounted on the scrubber side wall penetrates deeply into the scrubber to avoid freezing of the dump valve.
