Variable displacement compressor |
摘要 |
A variable displacement compressor for efficiently cooling and lubricating seals arranged on a rotary shaft. The seals are arranged at end portions of the rotary shaft that project from a housing of the compressor. A first lubrication chamber is defined by a first seal in the housing around the front end portion of the rotary shaft. A second lubrication chamber is defined by a second seal in the housing around the rear end portion of the rotary shaft. A shaft passage extends through the rotary shaft to connect the first and second lubrication chambers. Refrigerant gas including lubricating oil flows from a crank chamber to a suction chamber via the first lubrication chamber, the shaft passage, and the second lubrication chamber. This efficiently cools and lubricates the seals.
