VALVE CONTROLLED FUEL HEATER WITH SELF-ADJUSTING VALVE

摘要

A fuel heater having a fuel passage therethrough and heated means as a part of the heater with a valve body movable between a first position and a second position by a temperature responsive means, the valve body at the first position directing the fuel through a first path in heat receiving relationship with the heated means and at the second position directing substantially all the fuel through a second path away from the heated means. The heater also includes hinge means operatively connecting the elongated valve stem and the valve body for permitting relative lateral movement therebetween and thereby tending to prevent binding of the valve body in a tube in which the valve body and stem are located.
