or jacket 02 is rotated a layer of oil forms on an interior surface of the casing or jacket 02 which oil layer has a certain thickness with that thickness depending primarily upon the speed of rotation of the casing or jacket 02 and the viscosity of the oil to also direct the lubricating oil through the bearing 03 a first outer oil deflector 11 is located in the lubricant chamber 08 this first outer oil deflector 11 scrapes off part of the layer of oil that has adhered to the interior surface of the casing 02 the first outer oil deflector 11 is positioned at a slight angle with respect to a diametral plane extending through the casing or jacket 02 in order to accelerate the scraped off oil in the axial direction of the cylinder the resulting flow of lubricant is represented by a dashed line in fig2 because the first outer oil deflector 11 is located in the lubricant chamber 08 near the bearing 03 the lubricant flow is directed axially through the bearing 03 as seen in fig2 axially interiorly of the bearing 03 in the direction of oil flow as seen in fig2 a radial oil layer again forms on the interior surface of the casing 02 in an axially interior lubricant chamber which is defined by the bearing assembly 03 and the lubricant side sealing ring to keep the pressure of the oil acting on the lubricant side sealing ring 09 low a second inner oil deflector 12 is provided in the interior lubricant chamber which second inner oil deflector 12 scrapes the lubricating oil off of the interior surface of the casing 02 and directs it toward.
