Abstract
A gasket is inserted between a housing filled with pressurized oil and a rotating shaft projects out from said housing. This gasket has two sealing lips which delimit between them a collecting chamber provided with a discharge passage for lubricant. A calibrated nozzle allows oil to be fed into the collecting chamber at a predetermined flow rate in order to lubricate the outer lip.
