A dividing slide (29) engaging in a groove (30) of the pump ring is provided to form a suction side (27) and an outlet side (28). An oil inlet channel (31) extends through the bearing element (21) from the lubricating oil container (7) to the suction side. The oil outlet (28) of the pump is connected to an oil outlet chamber (32) at the end of the main shaft (18) from which oil is fed to the eccentric bearing (17) and the main bearing (19).
