The device to fill and drain a reservoir with oil and oil products comprises a liquid oil product flow distributor and a bent pipeline 1 to supply and drain liquid oil products, having a vertical section for connection with the distributor arranged in the form of two coaxially inner 2 and outer 3 conical guides of the flow arranged at the angle to the flow and connected to each other using connecting elements 4. The outer 2 and inner 3 conical guides of the flow are arranged as diverting, with formation of a diffuser circular channel of liquid oil product outflow. The angle at the top of the outer conical guide of the flow is selected from 148° to 154°, and the angle at the top of the inner conical guide of the flow is selected from 138° to 142°. The area of connection of the bent pipeline and the outer conical guide of the flow is arranged as rounded. The angle of flow generation is selected from 29° to 35°. Connecting elements 4 of the outer 2 and inner 3 conical guides of the oil product flow are made with a profile of guide vanes to ensure laminar flow of the liquid oil product. The point of connection of the inner conical guide with a reflecting disc 5 is made as rounded.
