Capacity varying type rotary compressor and refrigeration system having the same
A capacity varying type rotary compressor and a refrigeration system having the same are provided. The capacity varying type rotary compressor includes a casing that contains a certain amount of oil and maintains a discharge pressure state; a motor installed in the casing that generates a driving force; one or more cylinder assembly fixed in the casing, having a compression space that compresses a refrigerant by a rolling piston that performs an orbit motion and a vane that performs a linear motion by contacting the rolling piston, and having a vane pressure chamber formed at a rear side of the vane that implements a normal driving as the vane contacts the rolling piston or a saving driving as the vane is separated from the rolling piston; and a mode switching device that selectively supplies a suction pressure or a discharge pressure to the vane pressure chamber of the cylinder assembly according to a driving mode.
