    Abstract: A direct suction hermetic compressor assembly is disclosed including a hermetically sealed housing (14) having enclosed therein a compressor mechanism discharging compressed gas refrigerant into the interior of the housing, thereby creating a high pressure housing. The compressor mechanism includes a crankcase (46) defining a suction cavity (62) into which low pressure suction gas is directly introduced. Bearings (80,84) in the crankcase communicate between the housing interior and the suction cavity, and rotatably support a crankshaft. Annular seals (182,184) received within grooves in the crankshaft bear against the bearings and are actuated and lubricated by oil fed from within the grooves to prevent high to low pressure gas leakage and to facilitate bearing lubrication. A scotch yoke mechanism operably couples a plurality of radially disposed pistons (96,98) to a crankshaft eccentric portion within the suction cavity. Oil ducts (186) open onto the loaded surface of the eccentric to limit oil leakage into the suction cavity.

    Abstract: A porous bronze 1b and a resin 1c impregnated in pores of the porous bronze 1b formed on a backing metal 1a constitute a bearing 1. At a surface to be brought into contact with a crank shaft 5, porous bronze 1b and resin 1c are sparsely exposed. Ratio of area of exposure of porous bronze 1b at the contact surface 1d is at least 5% and at most 60%. Thus a bearing for a refrigerating compressor having high seizure resistance at the time of boundary lubrication and having small amount of wear caused by sliding as well as a refrigerating compressor employing the same can be obtained.

    Abstract: The invention relates to a guide block and a method for embodying divisions on a slide plane (22) of a guide block blank (47). The divisions (25) are applied to the guide block blank (47), then a base surface (26) for the slide plane (22) on the guide block blank (47) is pre-prepared. After introduction of a material (41) for application to the base surface (26), a local fusion of the introduced material (41) is carried out, by means of a non-contact heat input (35). Particular forms for the divisions (25) are generated by means of moving the guide block blank (47) and/or a beam (35) of the heat input (34) relative to each other. Finally the support surfaces of the molten material (41) are levelled to generate a planar support surface for the slide plane (22).
