Abstract: A compressor may include a shell assembly, a first scroll, a second scroll, a driveshaft, and a bearing. The first scroll includes a first end plate and a first spiral wrap extending from the first end plate. The second scroll includes a second end plate and a second spiral wrap extending from the second end plate. The spiral wraps engage each other to form fluid pockets. The driveshaft may engage one of the scrolls. The bearing supports the driveshaft for rotation relative to the shell assembly. The bearing includes first and second axial ends and an aperture extending through the first and second axial ends. The driveshaft extends through the aperture. The aperture is defined by an inner diametrical surface of the bearing. The inner diametrical surface may include a tapered portion that extends radially outward as the tapered portion extends axially toward the first axial end of the bearing.

Abstract: A drive for a mobile compressor includes EMI and transient protection circuits, second chokes, converters and an inverter. The EMI and transient protection circuits include respectively common mode chokes and at least one component. Each of the common mode chokes is configured to receive a first direct current voltage and is connected to first and second grounds. The at least one component is connected to a third ground. The first, second and third grounds are at different voltage potentials. The second chokes are connected downstream from the common mode chokes. The converters are connected to outputs of the second chokes and are configured to collectively provide a second direct current voltage to a direct current bus. The inverter is connected to the direct current bus and configured to convert the second direct current voltage to an alternating current voltage to power the mobile compressor downstream from the inverter.

Abstract: An optocoupler circuit includes first and second resistors, an optocoupler, a reference circuit, and a comparator. The optocoupler includes a light source and a phototransistor. The light source is connected to form a first voltage divider with the first resistor. The phototransistor is connected to form a second voltage divider with the second resistor. The optocoupler transitions an output of the second voltage divider between first and second levels. Magnitudes of the first and second levels are greater than zero. The reference circuit is configured to output a reference voltage. The comparator includes a first input and a second input. The first input receives an output of the first voltage divider. The second input receives the reference voltage. An output of the comparator transitions between a third level and a fourth level based on a comparison between the output of the first voltage divider and the reference voltage.

Abstract: A method of manufacturing an impeller includes attaching blades to a hub. The impeller includes the blades, the hub, and a shroud. The blades each include a tip, and the shroud includes an inner surface and at least one ring extending from the inner surface. The method also includes applying a brazing compound to the tips of the blades and to the inner surface of the shroud. The method includes inserting the blades and the hub into the shroud such that the tips of the blades press against the rings. The rings and the tips of the blades form an interference fit between the rings and the tips of the blades that maintains a consistent gap between the shroud and the blades during manufacture of the impeller. A compressor including the impeller is also disclosed.

Abstract: A compressor includes a shell, first and second scroll members, a fitting assembly and a valve assembly. The first scroll member includes a first end plate having a first spiral wrap extending therefrom. The second scroll member includes a second end plate having a second spiral wrap extending therefrom and an injection passage formed in the second end plate. The second spiral wrap is meshingly engaged with the first spiral wrap to form compression pockets. The injection passage is in fluid communication with the compression pockets. The fitting assembly is in fluid communication with the injection passage. The valve assembly coupled to one of the second scroll member and the fitting assembly and movable between a closed position in which fluid communication between the compression pockets and the suction chamber is prevented and an open position in which fluid communication between the compression pockets and the suction chamber is allowed.

Abstract: A system may include a first compressor, a second compressor, a first heat exchanger and a second heat exchanger. The first compressor has a first inlet and a first outlet. The second compressor is a sumpless compressor and has a second inlet and a second outlet. The second compressor provides working fluid discharged from the second outlet to the first compressor. The first heat exchanger is disposed upstream of the second compressor and provides working fluid to the second compressor. The second heat exchanger is disposed upstream of the first compressor and provides working fluid to the first compressor.

Abstract: Systems and methods for purging lubricant from a first compressor to a second compressor are provided. A control module receives a lubricant purge command, shuts the second compressor to an OFF-mode while the first compressor remains in the ON-mode, restricts working fluid from an outlet of the second compressor from flowing into the first compressor and allows compressed working fluid discharged from an outlet of the first compressor to flow into the inlet of the second compressor such that lubricant in the second compressor flows into the first compressor.

Abstract: A compressor (10) includes a compression mechanism (18) and a driveshaft (62) that drives the compression mechanism (18). The driveshaft (62) may include a first axially extending passage (94), a second axially extending passage (96), and a lubricant distribution passage (100). The first and second axially extending passages (94, 96) may be radially offset from each other and may intersect each other at an overlap region (98). The first and second axially extending passages (94, 96) are in fluid communication with each other at the overlap region (98). The lubricant distribution passage (100) may extend from the first axially extending passage (94) through an outer diametrical surface of the driveshaft (62). The lubricant distribution passage (100) may be disposed at a first axial distance (D1) from a first axial end (90) of the driveshaft (62). A first axial end of the overlap region (98) may be disposed at a second axial distance (D2) from the first axial end (90) of the drive shaft (62). The first axial distance (D1) is greater than the second axial distance (D2).

Abstract: An electrochemical climate control system circulates a working fluid comprising ammonia (NH 3 ) and hydrogen (H 2 ). An evaporator volatilizes liquid ammonia for a refrigeration effect. An electrochemical device can increase a total pressure of the working fluid and/or a first partial pressure of ammonia and decrease a second partial pressure of hydrogen when an f is applied. A condenser cools the working fluid/transforms ammonia to a liquid. A separator separates liquid ammonia from gas phase hydrogen. A heat exchanger may be provided downstream of the evaporator. The system may include an ejector combining vapor phase ammonia and gas phase hydrogen in a pressurized stream. A second electrochemical device is optionally included that decreases a pressure of gas phase hydrogen exiting the separator and which generates electrical potential that is transferred to the first electrochemical device. Such high efficiency systems may be free of any mechanical pumps or moving parts.
