<p>1. A piston lubrication device for a compressor operating on a gaseous fluid and comprising a cylinder (12) delimiting at least one compression chamber (11) and provided with fluid inlet means (16 to 19) and fluid outlet means (20 to 23), at least one movable piston (13) in the cylinder (12) and sealing means (27, 29, 30) allowing to seal the compression chamber (11), characterized in that the lubrication of the piston (13) is obtained by a wick (32) which is integral with the body of the cylinder (24) and surrounds the piston (13) in the form of a ring, this wick being installed between first (27) and second sealing means (29, 30), the second means isolating the wick against the compression chamber, said wick having one end dipped into a container (36) which is filled with a lubrifying liquid (52), whereas the other end is constituted by the ring around the piston (13).</p> |
