摘要： A gerotor pump assembly, and a system and method for operating a gerotor pump assembly, result in a lubrication strategy for operating in a loss-of-prime mode. An inner drive gear may be rotated in a first direction and in a second opposite direction about an axis of rotation. The inner drive gear has a number of projections extending outwardly therefrom. An outer driven gear surrounds the inner drive gear and defines a number of recessions along an inner surface configured to engage with the projections of the inner drive gear. The outer driven gear and the inner drive gear further define at least one dynamically-changing fluid cavity therebetween. The inner drive gear and the outer driven gear define an oil transfer volume clearance between a projection and a recession in a fully engaged position. Oil is maintained within the oil transfer volume clearance as the inner drive gear is rotated.

摘要： A compressor includes a shell, a first temperature sensor, a second temperature sensor, and a control module. The shell includes a motor, a compression mechanism and a lubricant sump. The first temperature sensor is at least partially disposed within the shell and configured to measure a first temperature of a lubricant at a first position. The second temperature sensor is at least partially disposed within the shell and configured to measure a second temperature of the lubricant at a second position that is vertically higher than the first position. The control module is in communication with the first and second temperature sensors and configured to determine a first difference between the first temperature and the second temperature. The control module is configured to determine whether a liquid level of the lubricant in the lubricant sump is below a predetermined level based on the first difference.

摘要： A vane-type compressor includes a rotor shaft that includes rotating shaft portions and a rotor portion, which are integrated with one another. A lower end of the rotating shaft is disposed in an oil reservoir. The vane-type compressor also includes vane aligners disposed at both end portions of vanes, and recess portions, which are respectively formed in a frame and a cylinder head so as to be concentric with an inner circumferential surface of a cylinder. Outer circumferential surfaces of the vane aligners are slidably supported by the recess portions. In the rotor shaft, oil supply channels, which allow communication between the oil reservoir and the recess portions of the frame and the cylinder head, and an oil pump, which supplies refrigerating machine oil in the oil reservoir to the oil supply channels, are provided.

摘要： An electric compressor includes a hollow cylindrical housing, a compression unit that compresses refrigerant, a motor that functions as a drive source of the compression unit, an inverter that controls the motor, and a refrigerant liquid accumulation unit that accumulates refrigerant liquid in the housing. The refrigerant liquid accumulation unit is disposed at a lower portion in the housing when the electric compressor is installed on the vehicle. According to the electric compressor, the refrigerant liquid is accumulated in the refrigerant liquid accumulation portion at a long-time stop, so that degradation of insulation property in the electric compressor (especially, of the motor and the inverter) can be prevented.
