Abstract: A compressor (10) may include first and second scrolls (68, 70), a seal assembly (20) and a valve ring (126). The first scroll (70) may include a first end plate (84) having a discharge passage(92), a modulation port (112), and a biasing passage (110). The modulation port (112) may be in communication with a first pocket (94) formed between spiral wraps (74, 86) of the first and second scrolls (68, 70). The biasing passage (110) may be in communication with a second pocket (96) formed between spiral wraps (74, 86) of the first and second scrolls (68, 70). The modulation valve ring (126) is axially displaceable relative to the seal assembly (20) and the first scroll (70) between first and second positions. The valve ring (126) may abut an end plate (84) of the first scroll (70) and close the modulation port (112) when in the first position. The valve ring (126) may abut an axially-facing surface of the seal assembly (20) and is spaced apart from the end plate (84) to open the modulation port (112) when in the second position.

Abstract: 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.
