    • A compressor system includes a compressor including a gas inlet and a lubricant inlet. The compressor is operable to compress a gas and discharge a mixed flow of compressed gas and lubricant. A valve housing includes a hot lubricant inlet, 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 position and a second position. The sleeve at least partially defines a mixing chamber and includes a first aperture in fluid communication with the hot lubricant inlet to selectively admit a hot lubricant into the mixing chamber and a second aperture in fluid communication with the cooled lubricant inlet to selectively admit a cooled lubricant into the mixing chamber. The hot lubricant and cooled lubricant mix in the mixing chamber to define a bulk lubricant that is directed to the lubricant inlet of the compressor via the lubricant outlet. A thermal element is positioned to sense a temperature and is coupled to the sleeve to move the sleeve in response to the sensed temperature. The movement of the sleeve is operable to vary the amount of hot lubricant admitted through the first aperture and to vary the amount of cooled lubricant admitted through the second aperture to control a temperature of the bulk lubricant.
    • 压缩机系统包括具有气体入口和润滑剂入口的压缩机。 压缩机可操作地压缩气体并排出压缩气体和润滑剂的混合流。 阀壳体包括热润滑剂入口,冷却润滑剂入口和连接到热和冷却的润滑剂入口的润滑剂出口。 套筒设置在阀壳体内并且可在第一位置和第二位置之间移动。 套筒至少部分地限定混合室,并且包括与热润滑剂入口流体连通的第一孔,以选择性地将热润滑剂进入混合室,以及与冷却的润滑剂入口流体连通的第二孔,以选择性地容许冷却的润滑剂 进入混合室。 热润滑剂和冷却的润滑剂在混合室中混合以形成通过润滑剂出口被引导到压缩机的润滑剂入口的大量润滑剂。 热元件被定位成感测温度并且耦合到套筒以响应于感测到的温度来移动套筒。 套筒的移动可操作以改变通过第一孔口进入的热润滑剂的量并且改变通过第二孔口进入的冷却润滑剂的量以控制散装润滑剂的温度。
