1. A compressor, comprising:
a casing;
a driving unit disposed in the casing;
a compression unit, coupled to the driving unit, configured to compress a refrigerant; and
a valve configured to control a flow of the refrigerant in the casing, wherein the valve includes:
a valve chamber including a main flow path, in which the refrigerant is to flow, the main flow path including a refrigerant inlet and a refrigerant outlet,
a floating body disposed in the valve chamber and including a flow path connecting between the refrigerant inlet and the refrigerant outlet, the floating body configured to be movable by the refrigerant passing through the flow path so as to open the main flow path when a pressure at the refrigerant inlet is greater than a pressure at the refrigerant outlet, and to close the main flow path when the pressure at the refrigerant inlet is not greater than the pressure at the refrigerant outlet, and
a bypass flow path, formed in the valve chamber, and configured to be opened by the floating body when the floating body is moved to close the main flow path to thereby allow the refrigerant to be detoured to the bypass flow path, and to be closed by the floating body when the floating body is moved to open the main flow path.
