摘要： A compressor system including a gas and a lubricant inlet. The compressor 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 connected to the hot and cooled lubricant inlets. 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 varys the amount of hot lubricant admitted through the first aperture and varys the amount of cooled lubricant admitted through the second aperture to control a lubricant temperature.

摘要： An air compressor that employs splash lubrication to lubricate and cool a piston kit that includes a cylinder and a piston reciprocating in the cylinder. In one form, cooling channels can be coupled to or formed on the cylinder to direct the lubricant that is splashed onto the cylinder to drain in a desired manner, such as helically around the exterior of the cylinder, to more effectively cool the piston kit. In another form, the cylinder can include an annular flange that can be bigger in diameter than a remainder of the cylinder. The annular flange can be received into a counterbore in a cylinder block. A cylinder head, which can be fastened to the cylinder block, can apply a clamping force to the annular flange to clamp or fix the cylinder to cylinder.
