Radial and axial sealing ring lubrication device for electrophotographic printer

摘要

The lubrication device uses a lubrication oil feed channel (FZ) provided by the reception device (AK) for a number of closely packed sealing rings (DR) and a distribution device with a channel system (RB,VR) for feeding the lubrication oil to the peripheral surface of the reception device. An overpressure valve connected to the channel system of the distribution device is opened when a given lubrication oil pressure is reached, with an indication of this oil pressure being reached provided.
