摘要： A simplified drive arrangement is provided to allow a scroll compressor to be operated at two capacity levels by a reversible electric motor. A pair of one-way clutches are positioned on a pair of parallel shafts. When the motor is driven in a forward direction drive passes through one of the one-way clutches and directly to the orbiting scroll. However, when the motor is driven in a reverse direction, drive passes through a countershaft, which in turn passes through a second one-way clutch. The drive passing through the second one-way clutch will result in the orbiting scroll being driven at a distinct speed then when the motor is driven in a reverse direction. In this way, capacity modulation is achieved with a very simple mechanism.

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.

摘要： A scroll compressor includes a non-orbiting scroll wherein the base is sealed to the housing. That is, the non-orbiting scroll provides the function of the scroll member, and also the function typically provided by a separator. A heat shield is positioned between the discharge pressure chamber and the base of the non-orbiting scroll. Leakage paths are provided to allow refrigerant to communicate between the discharge pressure chamber and spaces between the heat shield and the non-orbiting scroll.

摘要： A unique protection circuit for a sealed compressor incorporates oil structure which directs a heated oil onto a motor protection circuit. The motor protection circuit is of the type which shuts down operation of an electric motor when a predetermined temperature is sensed. The motor protection circuit is positioned adjacent to an oil return path which is opened when a high temperature is experienced in the compressor pump unit. The valve in the path opens to allow flow of the returned oil onto the motor protection switch. The motor protection switch is then actuated to stop further operation of the motor. In another embodiment, the motor protection switch is immersed in the oil sump. Again, when the oil temperature increases to a predetermined amount, the motor protection switch stops further operation of the motor.

摘要： An improved compressor incorporates structure for facilitating the alignment of a suction tube with the motor stator windings. In one embodiment, the motor stator is provided with a protective coating such that the refrigerant entering the compressor housing through the suction tube does not damage the motor windings. In another feature, the chamber housing is bumped out in the location where the suction tube is mounted such that the distance between the radially inner end of the suction tube and the radially outer portion of the windings is increased. The above provides better protection for the motor windings in a sealed compressor wherein the suction tube is axially aligned with the motor windings.

摘要： Several discharge check valve arrangements for scroll compressors move the check valve closer to the discharge port and the compression chambers. This reduces the amount of discharge pressure backflow, and thus reduces the amount of reverse rotation at shutdown. In one type of check valve arrangement, a plug is mounted within a check valve chamber to provide a stop for the check valve. The plug allows the check valve to seat against its valve seat while the compressor is operating to allow gas to flow around the check valve into a discharge plenum. At shutdown, the check valve arrangement is constructed to cause the check valve to rapidly close the discharge port. In other arrangements, the discharge check valve assembly may be mounted in a separator plate as a separate valve plug. This embodiment is similar to an earlier embodiment in the basic operation of the check valve.
摘要翻译：用于涡旋压缩机的多个排放止回阀装置将止回阀移动到更靠近排出口和压缩室的位置。这减少了排出压力的回流量，从而减少了关闭时的反转量。在一种类型的止回阀装置中，塞子安装在止回阀室内以为止回阀提供停止。当压缩机运行时，该插头允许止回阀抵靠其阀座座位，以允许气体在止回阀周围流动到排气室。关闭时，止回阀装置构造成使止回阀快速关闭排放口。在其他布置中，排放止回阀组件可以作为单独的阀塞安装在隔板中。该实施例与止回阀的基本操作中的早期实施例类似。
