초록

A refrigerator includes a gas flow generator formed with passages providing communication between an annular inlet chamber and a gas flow chamber, so that gas under pressure in the inlet chamber flows through the passages into the gas flow chamber. An energy transfer tube has a cylindrical interior space in communication with the gas flow chamber at one end of the tube and a throttle valve is installed in the energy transfer tube at its opposite end. An acoustic tone at a frequency in the range between about 1 kHz and about 20 kHz is spontaneously genera...

청구항

The invention claimed is: 1. A refrigerator comprising: an inlet device for receiving a flow of gas under pressure, the inlet device having a cylindrical interior surface bounding an inlet chamber outwardly, a gas flow generator having a cylindrical exterior surface bounding the inlet chamber inwardly and also having a cylindrical interior surface bounding a gas flow chamber, the gas flow generator having inclined passages that provide communication between the inlet chamber and the gas flow chamber, so that gas under pressure in the inlet chamber flows...
