Abstract

PURPOSE: To intensively control a cold gas amount to a chamber to be cold stored by forming a damper provided between refrigerated chambers of a refrigerator in a double cylindrical shape to be rotatable, and regulating positions of openings of inner and outer ducts, and controlling the gas amount. CONSTITUTION: An inner duct 2 of a damper to be a double rotation type for regulating a cold gas amount to a refrigerated chamber is coupled to a stepping motor 3, which is fixed to an outer duct 1. Openings 4a to 4c communicating with the chambers to be cold stored are provided at the duct 1. The opening of the duct 2 rotated by the motor 3 is brought into coincidence with the opening so that the gas is fed to the respective chambers. Thus, the gas amounts to the chambers can be intensively controlled.
