ROTARY COMPRESSOR AND REFRIGERATING CYCLE DEVICE HAVING SAME

摘要

A rotary compressor and a refrigeration cycle device having same. The rotary compressor is located in a closed housing (1). The closed housing accommodates a motor part (6) composed of a stator (7) fixed in the housing (1) and a rotor (8) rotating with a certain air gap kept from a inner surface of the stator (7), a compression mechanism section (4) comprising a crankshaft (10) and a rolling piston (66) rotating through the rotor (8), at least two supporting components (15, 28) supporting the compression mechanism section (4) rotating repeatedly and a buffer component (32) limiting the range of the repeated rotating. A suction pipe (50) or an exhaust pipe (51) communicated with the compression mechanism section (4) is in sliding fit with the housing (1). The suction pipe (50) or the exhaust pipe (51) opens to an additional closed chamber (55) on the housing (1).
