    摘要： A device for use in improving the heating efficiency of a water heater comprises a housing mounted over the heat collecting pieces of the water heater and provided with at least a set of ventilating ports, each of which is composed of a predetermined number of ventilation holes arranged in a geometric pattern. Pivoted to each of the ventilation holes is a damper, which can be triggered by a heat sensing element to turn so as to open or close automatically the ventiation holes. The heat sensing element is caused by heat to deform in order to bring about a displacement of the damper. The extent of the opening of the ventilation holes depends on the extent of the displacement of the damper.

    摘要： A temperature-dependent flow regulator for a combustion exhaust flue comprises a vent pipe connected to the flue by a first end, the opposite end having a movable valve member disposed therein, and thermostatic expansion means sensing the temperature of the flue, the expansion means being directly connected to the valve member via a linkage. The expansion means directly drives the valve member, independently of suction created by draft in the flue.

    摘要： Thermally actuated damper for vents or flues of gas-fired heating appliances having bimetallic slotted blades each of which performs both the sensing and the closing function. In the present invention the slots, which are necessary to enable the bimetal blade to flex in the desired direction, are covered, or eliminated, or substantially reduced for a more complete closure of the damper in the closed position.

    摘要： A gas fired heating installation in which several gas heater assemblies communicate with a common flue on different levels for drawing air of combustion from the flue and discharging combustion gases into the flue is equipped with a thermostatically controlled throttling valve in the intake duct of each heater assembly. As the temperature of the gas entering the assembly rises because of operation of a heater on a lower level, the throttle valve increases the flow section of the intake duct so that the gas, partly stripped of its oxygen by the lower heater, enters the higher heater in greater volume to provide an amount of oxygen approximately independent of the number of operating heaters.
