Title:
GM冷凍機
Document Type and Number:
Japanese Patent JP6658120
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a GM freezer comprising one compressor and several freezing generation parts and capable of restricting reduction of high pressure applied to each of the freezing generation parts.SOLUTION: A GM freezer 1 comprises one compressor 100 and two freezing generation parts 10A, 10B. Each of the freezing generation parts 10A, 10B is provided with an encoder 9 for detecting a rotating angle of an output shaft 54 expressing an opened or closed state of a high pressure valve 84. An opening timing of the high pressure valve 84 of each of the freezing generation parts 10A, 10B is adjusted by an opening timing adjustment device 110 on the basis of a rotating angle of the output shaft 54 detected by the encoder 9 of each of the freezing generation parts 10A, 10B so as not to cause an opening work period of the high pressure valve 84 at each of the freezing generation parts 10A, 10B to be overlapped.SELECTED DRAWING: Figure 2
