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 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 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.
摘要翻译：涡旋压缩机通过使其吸管与其电动机定子绕组对准而具有降低的高度。油通过限制油流过多个结构中的任何一个而从涡旋压缩机返回到压缩机油槽，使得其与通过吸入管进入吸入室的制冷剂隔离。以这种方式，通常在定子和壳体的内壁之间返回的油不与进入壳体的制冷剂连通。虽然在涡旋压缩机中示出了本发明，但是在其它类型的压缩机中具有优点。

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： A two-stage reciprocating compressor is provided. The compressor includes a block with a single cylinder and associated single compression chamber and single piston. The compressor further includes a crankshaft. The crankshaft has an eccentric crankpin that is operatively connected to the piston. A reversible motor is provided to rotate the crankshaft in a forward direction and in a reverse direction. An eccentric cam is rotatably mounted on the eccentric crankpin. The eccentric cam is held stationary with respect to the crankpin when the crankshaft is rotating in the forward direction. When rotating in the forward direction, the crankshaft drives the piston at a full stroke between a bottom position and a top dead center position. The eccentric cam rotates with respect to the crankpin when the crankshaft is rotating in the reverse direction. When rotating in the reverse direction, the crankshaft drives the piston at a reduced stroke between an intermediate position and the top dead center position.

摘要： For a refrigerant compressor having two capacities, a camming structure operable in different manners depending on direction of crankshaft rotation, to achieve each capacity while providing top dead center piston operation thru the use of a circular cam bushing which is eccentrically, rotatably mounted on the crankshaft eccentric and within the connecting rod bearing wherein the combined eccentricities of the bushing and the eccentric equal the primary stroke of the piston. A first stop mechanism is provided for stabilizing the bushing on the eccentric upon rotation of the crankshaft in one direction whereby the eccentricities of the eccentric and bushing become aligned and remain so during synchronous rotational orbiting motion of the eccentric and bushing during rotation of the crankshaft for producing full stroke and full capacity. A second stop mechanism is provided for stabilizing the bushing within the bearing upon opposite rotation of the crankshaft whereby the bushing eccentricity becomes and remains substantially aligned with the connecting rod stroke axis while the eccentric moves alone thru its rotational orbit for producing reduced stroke and reduced capacity. A unique electrical control system is also provided for a reversible electric induction motor for selectively and efficiently driving the compressor crankshaft in either direction for providing the different capacities.

摘要： A scroll compressor is mounted at an angle between vertical and horizontal. In this way, the overall height of the compressor is reduced compared to a vertical compressor. Thus, when only a smaller vertical size is available for mounting, the compressor will be useable. On the other hand, if the compressor were mounted directly horizontally, problems would arise with regard to providing proper lubrication. Since the compressor housing is angled, oil collects at an end of the housing remote from the pump unit. An oil delivery system is also provided including an oil slinger to deliver oil into an oil reservoir. An oil pickup tube associated with the shaft is received in the oil reservoir and delivers lubricant to locations along the shaft as needed.
