1,049,951. Valves. KLEIN, SCHANZLIN & BECKER A.G. Feb. 13, 1964 [April 27, 1963], No. 6015/64. Heading F2V. [Also in Divisions F4 and G1] In a thermostatically controlled steam trap a valve is closed against the direction of flow of condensate by pairs of bimetallic plates 7, the plates of each pair curving in opposite directions and the convex side of at least one plate abutting the concave side of at least one curved spring plate 8. As the temperature rises the conical spring plate is flattened. Couples comprising a spring and bimetallic plate may be arranged in series or a number of spring plates of different sizes and shapes may be mounted with a bimetallic plate. Recesses may be provided at the edges of the spring and/or bimetallic plate, so that the plates only bear together by part of their edges. |
