Abstract

820,039. Refrigerating. RANCO Inc. March 6, 1957 [March 21, 1956], No. 7399/57. Drawings to Specification. Class 29 [Also in Group XXXVII] In a refrigerating system in which the compressor motor is controlled by a temperature-responsive switch in the cooling chamber, the compressor motor is switched off by a pressure-responsive switch (see Group XXXVII) when the refrigerant pressure exceeds a predetermined minimum or maximum value.
