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： 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： 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 lower end cap for a scroll compressor includes a plurality of generally u-shaped surfaces, wherein the u-shaped surfaces have circumferentially spaced gaps. The gaps provide a location for mounting a weld seam from the center shell. The gaps are preferably machined at an outer periphery to provide a guiding surface for the center shell.

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： A compressor is provided with an electrical connection within the length of the stator winding or another component, to reduce the total height of the compressor. The compressor includes a motor having a stator and a rotor, wherein the stator extends along an axis for a fixed axial length and the rotor rotates about the axis. The compressor also includes a set of terminal pins extending through the housing for providing electrical connection to the motor. The terminal pins are mounted onto the inside of the housing of the compressor and within the axial length of the stator. A connector having cooperating slots slides in a direction generally parallel, tangential or a combination thereof to the axis of rotation to connect the terminal pins to the motor.

摘要： A non-orbiting scroll has structure which interfits with the crankcase towers. The crankcase towers are circumferentially spaced by gaps, and the non-orbiting scroll has tabs which extend into those gaps. The crankcase towers preferably fit into grooves in the non-orbiting scroll. The crankcase towers and the grooves on the non-orbiting scroll properly position the non-orbiting scroll and the crankcase relative to each other. The tabs extending into the gaps between the crankcase towers prevent the ingress of welding material into the compressor housing.

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： A valve return passage for quickly returning a valve to a closed position, includes return passages for communicating discharge pressurized fluid to a rear surface of a floating valve. The use of the return passages ensures that pressurized gas is communicated quickly to close the valve at shut down. This reduces the noise of operation of the compressor.
