THERMOSTATICALLY CONTROLLED HEATER FOR GAS FUEL AND GAS PRESSURE REGULATOR

摘要

A heater for gas fuel mounted to a pressure reducing regulator to warm the g as after the temperature is reduced by the pressure reduction. The heater receives th e fuel from the regulator through an external pipe and has separate gas and coolant passages therein. The coolant passage receives liquid engine coolant that heats both the gas and t he regulator. A heater core has a plurality of radially extending fins around which the gas passes with the coolant passing through the interior of the core. Coolant flow is regulated by a thermostat that is responsive to the temperature of the gas to open and close the coola nt passage.
