摘要： A scroll-type compressor includes a compression-chamber-forming member, a housing, an injection passage part, and a relief mechanism. The compression-chamber-forming member forms a compression chamber and has a movable scroll and a fixed scroll. The housing forms a back pressure chamber. Refrigerant to apply back pressure to the compression-chamber-forming member is accumulated in the back pressure chamber. The injection passage part is linked to the compression chamber. The relief mechanism is configured to establish a communication between the compression chamber and the back pressure chamber communicating when injection pressure of the refrigerant flowing from the injection passage part into the compression chamber is higher than the pressure in the back pressure chamber.

摘要： A scroll compressor includes a fixed scroll and an orbiting scroll, which are made of materials having different strengths and which include respective scroll laps. The scroll lap of the fixed scroll and the orbiting scroll having a lower material strength has a thickness satisfying tl=2aα, where tl represents scroll lap thickness, a represents basic circle radius, and α represents phase angle. The scroll lap of the fixed scroll and the orbiting scroll having a higher material strength has a thickness satisfying th=2aβ, where th represents scroll lap thickness, a represents basic circle radius, and β represents phase angle. The scroll lap thickness th of the fixed scroll and the orbiting scroll having the higher material strength is set to be less than the scroll lap thickness tl of the fixed scroll and the orbiting scroll having the lower material strength.

摘要： A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

摘要： A compressor includes a housing, compression unit, discharge chamber, outlet, and oil separation structure. The oil separation structure, which is arranged between the discharge chamber and the outlet, includes an oil reservoir, oil separation compartment, intake passage, exhaust passage, and supply passage. The oil separation compartment is located upward from the oil reservoir. The intake passage, which extends upward from the oil separation compartment, draws refrigerant gas into the oil separation compartment from the discharge chamber to separate lubrication oil from the refrigerant gas. The exhaust passage extends upward from the oil separation compartment and discharges the refrigerant gas in the oil separation compartment out of the housing through the outlet. The supply passage extends upward from the oil separation compartment and has a larger cross-sectional area than the intake passage. The supply passage supplies the oil reservoir with lubrication oil from the oil separation compartment.
