ABSTRACT:
Apparatus for rapidly exhausting air pressure from an intercooler pneumatically connected to receive compressed air from an air compressor. The apparatus includes a blowdown valve pneumatically connected to receive air pressure contained in the intercooler. The valve has a large exhaust port and a valve member seatable against the port to open and close the same. An inlet port is provided for admitting a compressor unload signal to the valve, with the unload signal being effective to move the valve member away from the large exhaust port to allow rapid exhaustion of intercooler air pressure to atmosphere through the exhaust port.
