摘要： A sealed compressor incorporates a relatively thin counterweight. The relatively thin counterweight is able to fit within a much smaller space than prior art cast counterweights. The relatively thin counterweight allows the reduction of the overall length of the sealed compressor, and thus provides very valuable benefits.
摘要翻译：密封压缩机结合了相对薄的配重。相对薄的配重能够适应比现有技术的铸造配重更小的空间。相对薄的配重允许密封压缩机的总长度的减小，从而提供非常有价值的益处。

摘要： A scroll compressor is provided within a sealed housing. Although the invention is shown with regard to a scroll compressor, it should be understood that aspects of the invention have benefit to any type sealed compressor. A lower bearing is attached directly to a housing end cap. The lower bearing is easily and accurately attached to the end cap, and reduces the complexity and cost of assembly of a sealed compressor. In particular, the end cap is provided with upset portions spaced circumferentially by gaps. The bearing is secured to the upset portions by welding. Oil can flow through the gaps and into a space beneath the bearing such that it can reach oil passages in the shaft.

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 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： Several transmission embodiments selectively communicate rotary drive to an orbiting scroll to achieve capacity modulation. In these embodiments, when the motor is driven in a first direction, the orbiting scroll is driven at a rate which is equal to the motor speed. However, if the motor is driven in a reverse direction, the orbit rate of the orbiting scroll is reduced. The transmission ensures that the orbiting scroll member itself is driven in the proper forward direction regardless of whether the motor is being driven in forward or reverse.

摘要： A number of scroll compressor designs protect the back chamber seals upon reverse rotation. In the prior art, scroll compressors are sometimes miswired and inadvertent reverse rotation results. In some applications, this has caused the seals to be crushed. The present invention ensures that upon reverse rotation, the pressure within the back chamber is maintained at suction pressure rather than the very low pressure which may be found in the compression chambers. The seals are protected. In one embodiment, a relief is formed at a seal groove to ensure suction pressure does communicate into the back chamber. In other embodiments, a valve controls the pressure in the back chamber. Upon normal operation, the valve allows pressure from the back pressure tap to communicate into the back chamber. During reverse rotation, the valve allows suction pressure to communicate to the back chamber.
摘要翻译：许多涡旋压缩机设计在反向旋转时保护后室密封。在现有技术中，涡旋式压缩机有时会出现连线错误，导致无意的反转。在一些应用中，这导致密封件被压碎。本发明确保在反向旋转时，后室中的压力保持在吸入压力而不是在压缩室中可以发现的非常低的压力。密封件受到保护。在一个实施例中，在密封槽处形成浮雕以确保吸入压力连通到后室。在其他实施例中，阀控制后室中的压力。在正常操作时，阀允许来自后压力抽头的压力连通到后室。在反向旋转期间，阀允许吸入压力与后室连通。

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。

摘要： Scroll compressors include a tap for communicating a compressed refrigerant to a back pressure chamber to resist a separating force. A restriction is placed within this tap to slow build-up of the back pressure chamber at start-up. Further, the restriction smoothes out any fluctuations in the back pressure force as the pressure in the compression chamber from which the refrigerant is tapped may fluctuate.
