1. A compressor comprising:
a casing;
a driving motor provided at an inner space of the casing;
a compression part disposed at the inner space of the casing and configured to compress refrigerant;
a rotating shaft connecting the driving motor to the compression part and configured to transmit driving force of the driving motor to the compression part; and
a refrigerant discharge pipe positioned through the casing and extending between a first end and a second end, the refrigerant discharge pipe defining an inlet at the first end and an outlet at the second end, the inlet being in fluid communication with the inner space of the casing and being apart from an upper end of the driving motor,
wherein the refrigerant discharge pipe defines a communication hole between the inlet and the outlet, the communication hole extending between an outer circumferential surface of the refrigerant discharge pipe and an inner circumferential surface of the refrigerant discharge pipe, and
wherein an oil blocking portion surrounding the refrigerant discharge pipe is positioned apart from the refrigerant discharge pipe and is provided at an outer circumferential portion of the refrigerant discharge pipe.
