Abstract: A hermetic rotary compressor includes a sealed case, an electrically-driven mechanism installed in the sealed case and a compressing mechanism for compressing the sucked-in refrigerant. The compressing mechanism has a cylinder defining a compression chamber into which an eccentric roller of the electrically-driven mechanism is accommodated. Upper and lower flanges are respectively fixed to upper and lower portions of the cylinder so as to support the rotary shaft and seal the compression chamber. At least one resonance chamber is formed at an inner peripheral surface of a discharge port formed in the upper flange, whereby the resonance chamber communicates with the discharge port. A closure member is provided for opening/closing the resonance chamber. The closure member is biased closed by a spring disposed in a hole formed at the inner peripheral surface of the discharge port of the upper flange, the hole and resonance chamber having a common entrance. The resonance chamber is opened during a compression operation and is closed when the refrigerant is discharged by the closure member.

Abstract: A rotor for a synchronous motor includes a main core which is formed with a shaft hole disposed in a center area thereof, a plurality of inductive conductor slots arranged along an outer area thereof, and a plurality of magnet slots each arranged between the shaft hole and the inductive conductor slots; an inductive conductor which is inserted into each inductive conductor slot; a first and a second permanent magnet units which each have at least one first permanent magnet and at least one second permanent magnet having different polarities, the first permanent magnet and the second permanent magnet being inserted into the magnet slots and being disposed opposite to each other with the shaft hole being interposed therebetween; and a magnetic flux loss prevention member which is disposed between the first permanent magnet unit and the second permanent magnet unit and prevents loss of magnetic flux, intervals between the inductive conductor slots become small as the inductive conductor slots go from centers of the first and second permanent magnet units to the magnetic flux loss prevention member. Thus, intervals of inductive conductor slots in which inductive conductors are inserted become small as the inductive conductor slots go from centers of permanent magnet units to a magnetic flux loss prevention member, and thus, torque ripple generated in a portion where polarities of permanent magnets are changed in driving a synchronous motor is prevented, thereby reducing vibrations and noises.
