    摘要： A scroll compressor housing has a center shell having an upper end defining an opening, and a top cap covering the opening and secured to the center shell. A crankcase is positioned within the housing. An orbiting scroll has a base plate and a spiral wrap extending axially from the orbiting scroll base plate. A 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 riser extends axially upwardly from the crankcase to provide a support surface for the fixed scroll. A radially extending flange on the crankcase is supported by an upper edge of the center shell and the fixed scroll is pinned between the top cap and the center shell. A fixed scroll seal sealingly engages the fixed scroll and the top cap to form a muffler chamber. A rabbet on the fixed scroll matingly engages a shoulder on the crankcase in order to fixedly align the fixed scroll and the crankcase.

    摘要： A high side co-rotational scroll compressor has lubricant sumps in both the discharge and suction pressure portions of its hermetic shell as well as a pressure biasing arrangement by which the scroll members are urged together in operation to minimize internal leakage. Lubrication of the bearing in which the driven scroll member rotates as well as to the bearing in which the idler scroll member rotates, both of which are located in the suction pressure portion of the shell, is provided for. Additionally, embodiments are taught by which the interface between the tips of the wraps of each scroll member and the end plate of the opposing scroll member are lubricated and by which the seal in the axial pressure biasing arrangement is lubricated and/or shielded from debris having the potential to damage it.

    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： An improved method of aligning the bearing components within a scroll compressor includes the step of mounting the crankcase to be an interference fit within the center shell, and having a surface abutting a true upper surface of the shell. This ensures that the axis of the bearing in the crankcase is idealized and centered on the center axis of the center shell. At the same time, the lower bearing is mounted on the lower end cap, and is also cut to be concentric with a force fit outer surface of the end cap. This ensures the lower bearing is also centered on the inner periphery of the center shell. Once it is ensured the center shell is true, then it is also thus ensured the upper and lower bearings are aligned on a common axis. An improved lower bearing structure with a reverse taper is also disclosed.

    摘要： A valve for selectively allowing the return of oil from a discharge plenum to a suction plenum includes a passage which is selectively opened or blocked by a valve spool. The valve spool sees a pressure from a discharge pressure location upstream of a discharge check valve on one face, and a discharge pressure from a discharge plenum on an opposed face. While the compressor is running, the two pressures should be relatively equal. The face which sees the pressure from the chamber upstream of the check valve is larger than the face which sees the pressure from the discharge plenum. Thus, when the compressor is running, the valve spool is biased to a first position at which it allows oil return from the discharge plenum to the suction plenum. However, upon shutdown of the compressor, the pressure in the chamber upstream of the discharge valve drops. The valve spool will be driven to a second position at which it blocks communication for oil return.

    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.
