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: 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: 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: 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: 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 scroll compressor has a reduced height by having its suction tube aligned with its motor stator windings. The oil is returned from the scroll compressor to a compressor sump by confining the oil to flow through any of several structures such that it is isolated from refrigerant passing into a suction chamber through the suction tube. In this way, the oil which has been typically returned between the stator and the inner wall of the housing does not communicate with the refrigerant which is entering the housing. While the invention is shown in scroll compressor, it has benefits in other type compressors.
