Abstract
A compressor system including a lubricant inlet compresses a gas and discharges a mixed flow of compressed gas and lubricant. A valve housing includes a hot and a cooled lubricant inlet, and a lubricant outlet. A sleeve is disposed within the valve housing and is movable between a first and a second position. The sleeve defines a mixing chamber and includes a first aperture with the hot lubricant inlet and a second aperture with the cooled lubricant inlet. The hot and cooled lubricant mix in the mixing chamber are directed to the lubricant inlet of the compressor. A thermal element is positioned to sense a temperature and moves the sleeve in response. The movement of the sleeve varies the amount of hot lubricant admitted through the first aperture and varies the amount of cooled lubricant admitted through the second aperture to control a lubricant temperature.
