Abstract
PURPOSE: To simplify the constitution of a cooling device mounting an injection cooling means on an enclosed compressor by operating a variable capacity valve with pressure of high pressure liquid refrigerant which has passed through a switch valve provided in a liquid refrigerant conduit of said cooling device.
CONSTITUTION: In a cooling device interconnecting sequentially an enclosed compressor 2 accommodating a motor body and compressor body 8 in an enclosed case 7, a condenser 3, a decompression expander 4 and an evapolator 5, said compressor body 8 is provided with a roller 13 eccentrically rotating while contacting the inside of a cylinder 9, a through hole 20 bypassing a portion of refrigerant being compressed to a low pressure chamber separated by a blade 14, a guide hole 22 provided orhtogonally to said hole 20 and having a variable capacity valve 21 opening and closing said hole 20 and an introducing hole 25 for introducing refrigerant bypassed by thr through hole 20 through suction space 24 into said low pressure chamber so as to operate said variable capacity valve 21 with the pressure of refrigerant which has passed through a switch valve 31.
