摘要： Rotor for an electric motor that comprises a core (1), segments of a cylinder (5, 6, 7) made of magnetizable materials, a substantially cylindrical retaining wrapper (10) whose end portions are joined to at least a pair of plane elements (8, 9). The rotor also comprises first elastic means (11, 12, 13) having a length that is not smaller than the length of the core and being supported by means (2, 3, 4) that are integrally provided in the core parallelly to the axis of rotation (X) of the rotor, which interfere with contiguous longitudinal edges of the segments of a cylinder so as to keep said segments circumferentially spaced from each other. In a preferred manner, the rotor also comprises second elastic means (21-26) which are adapted to make up for the longitudinal and radial plays of the various parts of the rotor so as to ensure that the outer surface of the segments of a cylinder keeps in contact with the inner surface of the wrapper. The invention further relates to a method for producing the rotor. Use: electronically commutated motors, eg. used to drive hermetic refrigerant compressors. Advantages: facilitates mass production, with a high quality-to-cost ratio.

摘要： Refrigeration compressor provided with a pan (18) for the evaporation of defrost water, attached to the shell (13) of the compressor by means of a profile section (19) that is applied so as to engage a through-aperture (22) provided in the body of the pan. The profile section (19) is adapted to get hooked on, with its V-shaped lower end portion, to one of the pipes (30) that shoot out of the compressor. The solution is simple and rational, enabling a single type of pan to be used for differently rated and, therefore, differently sized compressors.

摘要： Hermetic refrigeration compressor for household and similar refrigeration appliances, comprising a sealed casing (12), whose bottom (10) forms a sump for the lubricating oil (14), in which there are housed both the actual compressor and the related driving motor (16) which share a hollow crankshaft (20) rotating about a vertical axis, pumping means (34, 36) for the lubricating oil being connected to the lower end portion of said crankshaft. Said pumping means comprise a sleeve (34), which is rigidly fixed at the lower end portion of the crankshaft (20), and a piston member (36) which is elastically connected to the stator (22) of the motor (16) and floats freely inside said sleeve.

摘要： Electric compressor comprising a compression cylinder and the respective head, a valve plate arranged between the head and the body of said cylinder and provided with a gas inlet opening, a silencer arranged at the inlet side of said opening and comprising an elongated portion with an aperture adapted to fit in with said opening. The head is provided externally with a concave recess which is laterally open towards the inner cavity of the compressor, said elongated portion of the silencer being firmly housed in said recess so that the aperture engages the opening in the valve plate in an air-tight, sealed manner. In said recess there is provided a hollow space between said elongated portion and the outer wall, said hollow space being adapted to accommodate an elastic element for locking the silencer in place.

摘要： The invention provides for the use, in the refrigerating circuit of a household or similar vapour-compression refrigeration apparatus, of the same control means (7) used for the driving motor of the compressor (1), which is a brushless-type motor, to also control electromagnetic valve means (8) located upstream of the capillary tube (4), said valve means being adapted to interrupt the flow of the refrigerant medium migrating from the condenser (2) to the evaporator (5) during the pauses in the operation of the compressor (1), wherein said control means (7) control a single electric parameter, such as preferably the power-supply frequency. In a preferred embodiment, the valve means (8) comprise at least a bistable valve.

摘要： Refrigerator or freezer apparatus, preferably of the household type, equipped with at least a hermetic reciprocating compressor provided with a brushless-type electric driving motor and electronic frequency control arrangement adapted to operate said motor at a plurality of different pre-selectable RPMs, wherein said compressor is provided with a protection feature constituted by a minimum pre-selectable RPM (Vmin) of said motor below which said control arrangement cuts off the operation of said motor. Furthermore, said control arrangement is adapted to select a motor RPM (Vmax) which is different from any pre-selectable RPM when said control arrangement is supplied with an external command or a particular combination of signals that are indicative of the operation of the refrigeration apparatus.
