Compressor

A compressor comprising:

• a housing having a delivery port;
• a compression unit accommodated in said housing and securing a discharge chamber between a wall of said housing and said unit, said compression unit carrying out a series of processes including suction of the refrigerant containing lubricating oil, compression of a sucked refrigerant and discharge of the compressed refrigerant into the discharge chamber;
• an oil separator for separating part of the lubricating oil from the refrigerant, said separator including a separation chamber formed in the wall of said housing into which said compressed refrigerant flows from the discharge chamber;
• path arrangement formed in the wall of said housing, for connecting the separation chamber and the delivery port, said path arrangement including a plurality of passages that have respective opening ends opening in an outer surface of said housing, one of the open ends serving as the discharge port, and form a delivery conduit extending from the separation chamber to the delivery port by being connected by one by one, and plug members for closing the opening ends except for the one forming the delivery port;
• and
• a safety device built in at least one of said plug members and is activated according to a state of the compressed refrigerant in said path arrangement, the state indicating at least either one of pressure and temperature of the compressed refrigerant.
