ABSTRACT:
An improved vane compressor including a novel lubricating oil separator means disposed within a discharge pressure chamber formed between the casing and the pump housing. The oil separator means comprises an element having a reticulate or spongy structure having pores communicating with each other and a shape substantially similar to that of the discharge pressure chamber, and baffle board guide means arranged for guiding fluid travelling in said element toward the outlet of the compressor. The oil separator element has a channel continuously formed in peripheral surfaces and an end surface thereof and adapted to cooperate with an associated inner surface of the discharge pressure chamber to form an oil passage for facilitating charge and discharge of oil through the oil charge and discharge port of the compressor.
