摘要： Refrigerated equipment is provided with an air passage through a wall thereof. A closure member within the passage is movable in opposite directions in response to overpressure or under pressure created within the refrigerated space upon opening or closing of a door. The closure member substantially completely closes the passage and means are provided for preventing the formation of ice between the sides of the passage and the closure which might otherwise interfere with the movement of the closure.
