摘要： An injection port (27) communicating with a compression chamber (25) in the course of compression is formed in a fixed scroll (30). Refrigeration oil separated from a refrigerant discharged from a scroll compressor (10) flows from the injection port (27) to the compression chamber (25) together with an intermediate pressure gaseous refrigerant. Each of bottom lands (31a, 41a) of the fixed scroll (30) and an orbiting scroll (40) has an intermediate bottom region (36, 46) facing the compression chamber (25) communicating with the injection port (27), and a suction side bottom region (35, 45) closer to an outer end of the lap (32, 42) than the intermediate bottom region (36, 46) is. A clearance between the bottom land (31a, 41a) and the end face (42a, 32a) of the lap (42, 32) is larger at the suction side bottom region (35, 45) than at the intermediate bottom region (36, 46).

摘要： On a drive shaft (23), formed is an oil discharge passage (71c, 72c, 73c) communicating with an oil supply hole (71a, 72a, 73a), having a flat surface or a recessed surface, and having a width that is less than or equal to a diameter of the oil supply hole (71a, 72a, 73a). A trailing edge of the oil discharge passage (71c, 72c, 73c) is displaced behind a trailing edge of the oil supply hole (71a, 72a, 73a) with respect to the rotation direction of the drive shaft (23). A foreign substance is prevented from being accumulated in the oil supply hole (71a, 72a, 73a) of the drive shaft (23) of the compressor, and therefore, damage to be done to the bearing (29a, 29b, 29c) is reduced.

摘要： 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.

摘要翻译：在驱动轴（23）上形成有与供油孔（71a，72a，73a）连通的具有平坦面或凹面的排油通路（71c，72c，73c），其宽度为小于或等于供油孔（71a，72a，73a）的直径。排油通道（71c，72c，73c）的后缘相对于驱动轴（23）的旋转方向在供油孔（71a，72a，73a）的后缘后方位移。由此，能够防止异物积存在压缩机的驱动轴23的供油孔71a，72a，73a中，从而减少对轴承29a，29b，29c的损伤。
