Abstract
A suction valve assembly for a compressor and a compressor having a suction valve assembly. The suction valve assembly may include a body that connects a compression chamber of the compressor with an accumulator, and a lifting/lowering valve provided in the body. The lifting/lowering valve may be moved upward by a pressure difference between an inner space of the accumulator and an inner space of the compression chamber when operation of the compressor stops and block reverse flow of oil to the accumulator. Accordingly, when operation of the compressor stops, compressed oil may be prevented from reversely flowing to the accumulator.
