Abstract: A discharge valve mechanism has discharge openings. The number of discharge openings to be placed in the open state is varied depending on the pressure and the flow rate of gas refrigerant discharged from a compression chamber. Accordingly, the occurrence of overcompression losses at the time of controlling of the variable displacement of a compressor is inhibited during the operation from small to large displacement. This achieves improvements in compressor operating efficiency.

Abstract: In a method of magnetizing a material of a permanent magnet portion provided in a rotor for a permanent-magnet motor, the material of the permanent magnet portion is embedded inside the rotor body, while the permanent magnet material has anisotropy in a direction penetrating the permanent magnet portion in section, and then the rotor is incorporated in a magnetizing unit and held in a rotatable manner, and the permanent magnet material is magnetized by flowing a magnetizing current through windings under the condition that the rotor is rotatably held in the magnetizing unit. Thus, the permanent magnet material is completely magnetized in a normalized direction, and even if the rotor is shifted from the normalized position, the rotor is retained back to the normalized position by a magnetic torque.

Abstract: The field magnet is formed of, for example, two permanent magnets, and a width of the field magnet increases from a center toward both ends thereof in a monotonically non-decreasing manner. The field magnet includes, at the both ends thereof, projecting portions projecting to a side opposite to a rotation axis. The field core includes a penetration hole through which the field magnet is caused to penetrate. The penetration hole includes penetration surfaces which cover magnetic pole surfaces of the field magnet, respectively. Specifically, the penetration surface includes concave portions with which the projecting portions are fitted. When the field magnet is inserted, the penetration surfaces serve as a guide which guides the field magnet, and accordingly the field magnet can be caused to penetrate through the penetration hole with ease.
