摘要： The present invention relates to a self-contained, portable refrigeration unit having a construction arrangement which enables it to be compatible with several models, types and variations of refrigeratable compartments. This refrigeration unit is represented by a refrigeration module (1) capable of being removably fitted into a refrigeratable compartment, comprising a first portion (100) and a second portion (200) associated with each other. The first portion (100) is in contact with the inside of the refrigeratable compartment and the second portion (200) is in contact with the outside of the refrigeratable compartment, and in some embodiments of the present invention, the first portion (100) is capable of moving in relation to the second portion (200). The first portion (100) comprises at least a first closed box (101 ) interfacing the refrigeration module (1 ) with the inside of the refrigeratable compartment. The second portion (200) comprises at least a second closed box (201 ) interfacing the refrigeration module (1 ) with the outside of the refrigeratable compartment. In another preferred embodiment, the first box (101 ) fits into the refrigeratable compartment through a fitting portion (111 ) whose cross section is smaller than the largest cross section of the second box (201). The present invention also relates to a refrigeration system (500) comprising at least one embodiment of the portable refrigeration module (1 ) mentioned above.

摘要： The metallurgical composition comprises a main particulate metallic material, for example iron or nickel, and at least one alloy element for hardening the main metallic material, which form a structural matrix (10); a particulate solid lubricant (20)., such as graphite, hexagonal boron nitride or mixture thereof; and a particulate alloy element which is capable of forming, during the sintering of the composition conformed by compaction or by injection molding, a liquid phase, agglomerating the solid lubricant (20) in discrete particles. The composition may comprise an alloy component to stabilize the alpha-iron matrix phase, during the sintering, in order to prevent the graphite solid lubricant from being solubilized in the iron. The invention further refers to a self-lubricating sintered product, obtained from the composition, and to the process for obtaining said product.

摘要： Discharge valve arrangement applied in a hermetic compressor used, for example, in household refrigeration systems comprising: a valve plate (10) closing an end of a compression cylinder (1) and provided with suction and discharge orifices (11, 12) contained within the inner contour of the axial projection (40) of the compression cylinder (1), said suction orifice (11) occupying an annular sector external to the axial projection of a discharge orifice (12) and being closed by a flexible suction vane (21) having a bending median portion (23). The valve plate (10) is provided with a plurality of discharge orifices (12) distributed in at least one of the regions defined externally and internally to the contour of the flexible suction vane (21), each discharge orifice (12) provided internally to the contour of the flexible suction vane (21) being axially aligned with a respective through opening (25) provided in said bending median portion (23).
