Abstract
A thermostat valve is provided for controlling gas flow to an infrared catalytic heater . The thermostat valve includes a thermally responsive snap member positioned within a housing central flow path and moveable with respect to the housing between open and closed positions. An elastomeric seal supported on the housing surrounds the central flow path and engages the snap member when in the closed position. A restricted flow path is provided in one of the housing and the snap disk for passing gas to the catalytic heater when the snap member is closed. The thermostat valve is relatively simple yet highly reliable.
