ABSTRACT OF THE DISCLOSURE The vane slot 20 and lubricating oil passageway 21 in the cylinder member 3 of a rotary vane compressor are configured such that the radial length of the slot wall 20a on the low pressure side of the vane 5 is less than that of the opposite wall 20b on the high pressure side. Such a shortened low pressure side slot wall reduces wear by providing improved lubrication at the critical inward edge of the slot (FI), and facilitates the flushing away of abrasive particles formed during the initial seating of the vane. For a horizontal installation the lubricating oil level is maintained below the radially outermost edge of the wall 20a to prevent the oil from being drawn into the low pressure chamber 17 when the compressor is stopped.
