(57) An air compressor of the rotary type comprising an external body (10) defining the
oil chamber (13) and an internal cylindrical body (11) or stator defining an air compression
chamber (14) in which a radial fin rotor (15) rotates. The compression or rotor chamber
(14) is connected on one side to an air inlet (21) and, on the other, to an exit port
(37) through means for separating the oil from the air under pressure, in which the
said oil separating means comprises a labyrinth path (38) inside the compressor (10),
delimited by diaphragms (40) and annular fins (39) placed in alternating radial planes
in the oil chamber (13), and in which the first diaphragm (40) counting from the air
exit port (37) from the compression chamber (14), presents an upper part (40a) coplanar
with the first fin (39) and extending downwards, on the two sides beyond the air exit
port (37) from the compression chamber (14).
