摘要： A scroll compressor includes a pressing mechanism and a back-flow prevention mechanism. The pressing mechanism includes a back-pressure chamber facing a back surface of a movable-scroll end plate, and a back-pressure supply path arranged to allow the back-pressure chamber to communicate with a compression chamber which is in a state right before the compression chamber communicates with an outlet port or a state in which the compression chamber communicates with the outlet port. The back-flow prevention mechanism allows refrigerant of the back-pressure supply path to flow from the compression chamber to the back-pressure chamber, and prevents fluid of the back-pressure supply path from returning from the back-pressure chamber to the compression chamber.

摘要： A fixed scroll is provided with a pin shaft portion which is formed in a cylindrical shape. Formed in a movable scroll is a slide groove which extends in the radial direction of the movable scroll. The pin shaft portion of the fixed scroll is engaged into the slide groove of the movable scroll. During orbital movement of the movable scroll, the pin shaft portion slidingly contacts a side surface of the slide groove, whereby rotation of the movable scroll is restricted.

摘要： A sealed type compressor includes a sealed vessel, compression and drive elements disposed in the sealed vessel, an oil pump and an oil supply groove. Upper and lower bearings sandwich the cylinder and piston of the compression element from respective axial sides. The drive element drives the compression element via a crank shaft. The lower bearing has an axially extending bearing portion to support the crankshaft. The oil pump draws up a lubricant into an oil channel extending in a shaft center direction of the crankshaft to provide lubrication to the compression and drive elements. The oil supply groove is provided at a sliding face of the bearing portion, and extends along the crankshaft to supply the lubricant to an outer surface of the crankshaft. The oil supply groove has a first open end side and a second closed end side at a lower end side of the crankshaft.

摘要： A compressor includes a casing configured to store lubricating oil in a bottom part, and a compression mechanism accommodated in an interior of the casing. Lubricating oil is separated out from high-pressure refrigerant discharged from the compression mechanism. Lubricating oil separated out by the oil separator flows from a high-pressure space formed in the interior of the casing and into which the high-pressure refrigerant flows. An ejector mechanism is disposed in the interior of the casing, preferably in the high-pressure space. The ejector mechanism includes a refrigerant-accelerating flow path in which the high-pressure refrigerant flows via a narrowed part in order to increase a flow rate of the high-pressure refrigerant, and an oil suction flow path merging with the refrigerant-accelerating flow path.
