Abstract: A scroll compressor includes an oil recollecting pump for recollecting oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor. A differential pressure hole is formed at a position where it communicates with compression chambers after a suction completion timing such that oil stored in an inner space of the shell can be supplied into the compression chambers using pressure difference between the high-pressure inner space of the shell and the low-pressure compression chambers, resulting in allowing oil to be smoothly supplied to a compression unit even during low-speed driving of the compressor and preventing beforehand an occurrence of a suction loss due to oil.

Abstract: (125) A scroll compressor is disclosed. The scroll compressor includes a rotating shaft coupling portion (153) axially extending from a central portion of an orbiting end plate (151) to radially overlap an orbiting wrap (152), such that an eccentric portion (1251) of a rotating shaft (125) is coupled thereto, and a portion of the orbiting wrap may extend from an end surface of the rotating shaft coupling portion (153) facing a fixed end plate (141). With the configuration, a distance between bearing reaction force and gas reaction force acting on the orbiting scroll can be reduced, to stabilize a behavior of the orbiting scroll and thus reduce back pressure, thereby decreasing friction loss between scrolls. Simultaneously, compression chambers can be formed even in a central portion of the orbiting scroll (150), which can increase a compression ratio and improve volumetric efficiency.

Abstract: A scroll compressor includes: a casing (110); a driving motor (120); a fixed scroll (140) which forms a compression space having a suction chamber, an intermediate pressure chamber and a discharge chamber, by being coupled to the orbiting scroll (150); and a discharge cover (190) installed at an inner space of the casing, having a space portion (191) communicated with a discharge chamber by being separated from the inner space of the casing, and having one or more discharge holes (195) on a side surface of the space portion corresponding to an inner wall surface of the casing, among surfaces of the space portion, the discharge hole for communicating inside and outside of the space portion with each other. With such a configuration, vibration noise of the compressor may be more reduced than in a case where an oil separator is installed outside the casing. Further, as an area of the discharge hole and a volume of the space portion are optimized, efficiency of the compressor may be enhanced.
