Abstract

915,284. Temperature-responsive actuating elements. CALUMET & HECLA Inc. June 26, 1961 [June 27, 1960], No. 23073/61. Class 64 (2). In a thermostatic device of the kind wherein thermal expansion of the fluid 32, contained in a sensing bulb 12 and connecting capillary tube 14, causes flexing of an elastomeric disc 24 in a housing 16 and thus movement of a piston 28 slidably mounted in the housing 16, or, as shown in a fitting 20 in the housing 16, the piston 28 is either, as shown, made of anti-friction material such as polytetrafluoroethylene or a washer of such material is interposed between the metal piston and the disc 24. The fluid 32 may be a silicone oil or a polyglycol.
