    摘要： A turbo compressor is provided that may include an impeller housing having an impeller accommodation space, an inlet formed at a first side of the impeller accommodation space, and an outlet formed at a second side of the impeller accommodation space that communicates with the inlet; an impeller accommodated in the impeller accommodation space of the impeller housing, rotated together with a rotary shaft by being coupled to the rotary shaft, and configured to centrifugally-compress a fluid suctioned through the inlet of the impeller housing and discharge the compressed fluid outside of the impeller housing through the outlet; a back pressure space formed between a rear surface of the impeller and the impeller housing; a back pressure passage connected between the outlet of the impeller housing and the back pressure space; and a back pressure control valve installed between the back pressure passage and the back pressure space, and configured to selectively open and close a region therebetween.

    摘要： Provided is a turbo compressor. The turbo compressor includes a driving shaft, a first impeller, a second impeller, a first shroud, a second shroud, a first-stage outflow passage, and a second-stage outflow passage. Also, the turbo compressor includes a gap adjustment passage that is branched from at least one of the first-stage outflow passage or the second-stage outflow passage to extend to the first shroud.

    摘要： A scroll compressor is provided. The scroll compressor may include a communication hole formed in a fixed scroll for communicating a discharge space and a thrust bearing surface with each other. This may reduce frictional loss between the fixed scroll and an orbiting scroll. Further, if a high vacuum state is about to occur during operation of the compressor, refrigerant in the discharge space may be introduced into the compression chambers through the communication hole. This may prevent the occurrence of a high vacuum state to thereby prevent damage to the compressor. Additionally, when the compressor is stopped, a pressure equilibrium operation may be performed through the communication hole.

    摘要翻译： 提供涡旋压缩机。 涡旋压缩机可以包括形成在固定涡旋件中的连通孔，用于将排出空间和止推轴承表面彼此连通。 这可以减少固定涡旋件和绕动涡旋件之间的摩擦损失。 此外，如果在压缩机运转期间即将发生高真空状态，则可以通过连通孔将放电空间中的制冷剂引入压缩室。 这可以防止高真空状态的发生，从而防止对压缩机的损坏。 此外，当压缩机停止时，可以通过连通孔执行压力平衡操作。

    摘要： A scroll compressor is provided that may include a casing; a drive motor; a fixed scroll that forms a compression space by being coupled to the orbiting scroll; and a discharge cover provided at an inner space of the casing, the discharge cover having a space that communicates with the compression space and separated from the inner space of the casing, and having one or more discharge hole on a side surface thereof, the one or more discharge hole providing communication between an inside and an outside of the space. With such a configuration, vibration noise of the scroll compressor may be more reduced in comparison with a case in which an oil separator is provided outside of the casing. Further, as an area of the one or more discharge hole and a volume of the space are optimized, efficiency of the scroll compressor may be enhanced.
