Abstract: An electrically-operated sealed compressor includes a cylinder, a cylinder head mounted on the cylinder and having a suction chamber and first and second discharge chambers, a piston accommodated in the cylinder, and a valve mechanism. The valve mechanism includes a suction muffler and a valve plate having at least one suction port, first and second discharge ports, and first and second pass holes. The first discharge port and the first pass hole communicate with the first discharge chamber, while the second discharge port and the second pass hole communicate with the second discharge chamber. The valve mechanism also includes first and second discharge valves mounted on the valve plate and accommodated in the first and second discharge chambers, respectively, a suction reed having a reed valve for selectively opening and closing the suction port, a discharge gasket for sealing the valve plate and the cylinder head, and a discharge muffler. The first and second discharge chambers are separated from each other by the discharge gasket to form respective independent spaces, while the first and second pass holes communicate with the discharge muffler.
