Title:
REFRIGERATING CYCLE DEVICE AND ROTARY HERMETIC COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2006/073048
Kind Code:
A1
Abstract:
A refrigerating cycle device has a pressure switching mechanism (K) for performing, depending on the magnitude of load, switching between a normal compression operation and an operation stop of one compression mechanism section (2) of a rotary hermetic compressor (C). The pressure switching mechanism (K) has a bifurcation tube (30) provided with an on-off valve (31) in its intermediate section and communicating the high pressure side of a refrigerating cycle and a suction tube (16b); an auxiliary suction tube (35) connected within an accumulator (17) to an end section of the suction tube; a check valve (36) installed on either the auxiliary suction tube (35) or the suction tube (16b) and preventing a reverse flow of a refrigerant into the accumulator (17); and a guide pipe (34) for fixing and holding either the suction tube (16b) or the auxiliary suction tube (35) at the accumulator (17).
