摘要： In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating concurrently about parallel, non-concentric axes to produce a relative orbital motion, a scroll member including an annular biasing chamber formed in one scroll member end plate opposite the scroll wrap and a passage from one of the chambers formed by the scroll wraps for providing fluid to the chamber. The fluid exerts a force upon a pressure plate secured to the opposing scroll end plate and thereby acts to bias the scroll wraps into contact with the opposing scroll end plate. Seals are provided in the biasing chamber of the scroll end plate to ensure contact with the pressure plate of the opposing scroll member.

摘要： A scroll compressor is provided having appropriate clearance for movement of the orbiting scroll member. Clearance is provided without requiring contact between the crankcase, which supports the orbiting scroll, and the non-orbiting scroll member. Clearance is established during the assembly process using installation tooling that establishes locations of components using a reference point. Clearance is also established using spacers.

摘要： Low voltage electrical power is supplied to a diagnostic control device in a sealed compressor. Electrical power is tapped from a high voltage power line and transformed to low voltage power that in turn operates the diagnostic control device. The diagnostic control device and the electric voltage transforming system are housed within the sealed compressor shell, thus eliminating the need for additional openings in the compressor shell. Other low voltage devices can be powered in this way.

摘要： A compressor diagnostic system incorporates a control which receives a plurality of data streams about various operational features of the compressor. As an example, both temperature and pressure of the suction and discharge refrigerant are taken and sent to the control. Moreover, information with regard to the power being supplied to the motor is taken and stored. All of this information is utilized at a control which compares the information to expected values and determines a fault based upon the evaluation. Moreover, in another feature of this invention, much of this data is stored, and maintained at the compressor. In the event of a compressor failure, this stored information will provide a maintenance worker with a good indication of why the compressor failed.

摘要： A refrigerant cycle is provided with an expansion device that is movable between a normal mode of operation and a low charge mode of operation. In the low charge mode of operation, the expansion device does not lower the pressure of the refrigerant as much as it does in its normal mode of operation. In this way, the relatively high pressure ratios that are experienced by a compressor during a low charge operation will not be experienced. Instead, the pressure ratio across the compressor is reduced during low charge operation, and the compressor will be better protected.

摘要： An improved motor protection switch incorporates a parallel feedback component mounted in parallel to a heater in a motor protection circuit. The parallel feedback component senses the temperature of a compressor component. If tie temperature increases then the current flow through the heater increases. This causes a motor protector switch to open. In this way, the feedback component provides feedback from the compressor pump unit to the motor protection circuit more quickly than in the prior art.

摘要： A scroll compressor is provided with structure between its slider block and its eccentric pin that allows relative movement, but limits such movement. In one embodiment, a spring biased piston resists relative movement between the slider block and the eccentric pin. In another embodiment, incrementally spaced indexed surfaces are defined. With either embodiment the amount of relative movement of the slider block is limited relative to the eccentric pin and hence between the wraps of the orbiting scrolls. This will result in quieter operation.

摘要： An improved scroll compressor having an axially movable non-orbiting scroll eliminates the need for a separator plate. With the elimination of the separator plate, a back pressure chamber is provided to resist the discharge pressure which will be directed against a rear face of the non-orbiting scroll. In other embodiments, a seal on the rear of the non-orbiting scroll contacts the inner periphery of the end cap. Various ways of increasing the discharge pressure volume, or eliminating undesirable noise are also disclosed. Further, several ways of connecting the end cap to the center shell are also disclosed.

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 number of improvements increase the flow of lubricant within a scroll compressor. A centrifugal oil separator is mounted on the discharge port to remove oil from the refrigerant. The oil is returned through a leak path such that the oil can easily return back to a suction pressure chamber. The leak path is preferably upstream of a check valve. Thus, at shutdown, the leak path will not allow upstream components to also equalize in pressure with the suction pressure chamber of the compressor. Further, a number of embodiments include ways of resisting flow of refrigerant through the leak path, while still allowing oil flow. A number of valve elements are described which perform this function. Alternatively, labyrinth flow paths, or positioning of the return paths such that it will be closed when the compressor is shut down are disclosed.
