摘要： A scroll compressor is provided with structure that allows a reduction or modulation in mass flow capacity. Structure is provided for controlling the back pressure force tending to bias one scroll into other. This structure defines two distinct back pressure chambers. Pressure fluid is not supplied to at least one of the back pressure chambers during modulated operation.

摘要： A scroll compressor having a housing containing an orbiting scroll and a non-orbiting scroll each having a base formed with a free side and a compression side and having an involute extending generally normally from the compression side, each the involute terminating in an axially outer, substantially planar edge and having a radially outer inlet end and a radially inner discharge end, the scrolls being mounted within the housing in mating arrangement about a center axis of the involutes for relative orbital motion for compressing gas between the base and adjacent side portions of the involutes, the orbiting scroll having special bearing structure for eliminating the laterally directed tipping forces which are generally experienced by the orbiting scrolls of conventional scroll compressors, the bearing structure having a bearing hub integral with the discharge end of the involute of the orbiting scroll, the hub having a cylindrical bore oriented substantially normal to the compression side of the orbiting scroll for rotatably receiving an eccentric shaft section of a compressor crankshaft, bearing means formed axially thru the base of the non-orbiting scroll, a crankshaft having an axial section and an eccentric section, the axial section being rotatably mounted in the bearing and the eccentric section being rotatably mounted in the hub, whereby rotation of the crankshaft will move the orbiting scroll thru an orbit relative to the non-orbiting scroll to thereby generate compression pockets between both the base and the involutes.

摘要： A scroll compressor includes structure between an eccentric and a slider block that separates the scroll wraps when the orbiting scroll is driven in a reverse direction by entrapped fluid. In the prior art, entrapped fluid sometimes has driven the orbiting scroll in a reverse direction at shutdown, resulting in undesirable noise. The present invention stops movement of the orbiting scroll relative to the fixed scroll during reverse rotation by opening the fluid chambers dissipating that pressure.

摘要： A high-side co-rotating refrigerant scroll compressor defines a lubricant sump in its discharge pressure portion. Lubricant is directed from that sump, through a passage which is at least partially defined by the shell of the compressor, to the bearings in which the scroll members rotate. Heat carried in the lubricant flowing through the passage is transferred through the compressor shell to the ambient. Subsequent to having lubricated the bearing in which the drive scroll member rotates, lubricant is diverted into a passage defined by the drive scroll member drive shaft and enters the stream of compressed discharge gas flowing therethrough. The lubricant is thereby prevented from entering the suction pressure portion of the compressor where it would otherwise heat compressor suction gas prior to the entry of that gas into the compressor's compression mechanism.
摘要翻译：高侧同向制冷剂涡旋压缩机在其排出压力部分中限定润滑油槽。润滑剂通过至少部分地由压缩机的壳体限定的通道引导到涡卷件旋转的轴承。流经通道的润滑剂中携带的热量通过压缩机壳体传递到环境中。在润滑驱动涡旋件旋转的轴承之后，润滑剂被转移到由驱动涡旋件驱动轴限定的通道中，并进入流过其中的压缩排出气体流。因此，防止润滑剂进入压缩机的吸入压力部分，否则在将气体进入压缩机的压缩机构之前，其将加热压缩机吸入气体。

摘要： A scroll compressor has a fixed scroll and an orbiting scroll nested with one another within a shell. The orbiting scroll has a base plate with a pair of opposed slots formed therein, and a spiral wrap extending axially from the base plate. The fixed scroll has a base plate and a spiral wrap extending axially from the fixed scroll base plate nested with the spiral wrap of the orbiting scroll. A pair of towers extends axially downwardly from the fixed scroll base plate, each tower having a slot formed therein, diametrically opposed from the slot formed in the other tower. An Oldham coupling has an annular ring with an irregular oval profile which closely follows the outermost radial surface of the spiral wraps as the scroll compressor operates. The Oldham coupling also has an asymmetric shape with respect to any vertical plane bisecting a central axis of the Oldham coupling. A pair of opposed keys extend axially from a first surface of the Oldham coupling slidingly engaging the slots in the towers. A second pair of opposed keys extend axially from a second surface of the Oldham coupling slidingly engaging the slots in the base plate of the orbiting scroll. The keys and slots interact as the orbiting scroll is driven by an eccentric pin on a crankshaft to create a non-rotating orbiting motion for the orbiting scroll.

摘要： A high side co-rotating refrigerant scroll compressor includes a motor disposed vertically above its compression mechanism. The discharge of gas from the compression mechanism is through the drive shaft of the drive scroll member which is rotatably supported at its distal end in an upper bearing. Upper bearing lubrication is accomplished by the disentrainment of oil from the mixture of compressed refrigerant gas and oil discharged from the compression mechanism in the vicinity of the bearing and by the direction of such disentrained oil to the bearing.
