摘要：
A refrigeration apparatus containing a thermostat, adapted for use in a food storage compartment potentially containing a flammable gas, includes a thermostat and an enclosure forming a chamber configured to house the thermostat. The enclosure has two umbrella-type check valves configured to permit gas to pass into the chamber or out of the chamber when a predetermined pressure differential exists between the chamber and the food storage compartment. The enclosure forms a seal with the thermostat so that gas only passes through the check valves.
