Class Information
Number: 137/309
Name: Fluid handling > Reversing valves - regenerative furnace type
Description: Fluid handling devices comprising four-way reversing valves disclosed for fluid distribution in connection with a regenerative type of furnace, gas generator, or similar circuit having two connections to two heat exchangers or regenerators, a connection for incoming air or fuel or both, and a connection to the exhaust stack, the valve being selectively movable into two positions; in one position the incoming air or fuel is passed through a first heat exchanger or regenerator to the furnace or gas generator, the exhaust gases passing through the second heat exchanger or regenerator to the exhaust stack; and in the other position of the valve the incoming air or fuel is passed through said second heat exchanger or regenerator, to the furnace or gas generator, and the exhaust gases pass through said first heat exchanger or regenerator to the exhaust stack.
