ABSTRACT:
An improved vane compressor including a novel lubricating oil separator disposed within a discharge pressure chamber formed between the casing and the pump housing. The oil separator comprises a pair of fluid-traversable upper and lower plates disposed within the discharge pressure chamber, an oil separating element interposed between said upper and lower plates, which preferably has a reticulate or spongy structure having pores communicating with each other, and a hollow cylindrical guide element fitted in the casing in a fashion covering the inner peripheral wall of the discharge pressure chamber but a lower part thereof, said guide element having a depression formed in a peripheral surface thereof and defining a passage for guiding a gaseous medium toward the compressor outlet, whereby oil separation takes place at multiple places, resulting in high rate of oil separation.
