LUBRICATING SYSTEM FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1996 - IPC

FIELD: engine engineering. SUBSTANCE: inlet of the delivery pump is in communication with the tank for oil circulation and outlet of the pump is connected with the inlet of the self-cleaning filter. The drain line of the filter is provided with a rotary filter whose outlet is connected with the tank. A separating device is incorporated between the inlet of the filter and inlet of the main oil pipe line. The separating device comprises heat controller and heat exchanger. The heat controller can be connected either to the point of flow separation or to the point where the flows unite. When the load, which acts on the engine, is reduced, the pressure at the filter outlet is maintained owing to the flow section of the by-pass line is less than that of the heat exchanger line. EFFECT: enhanced efficiency. 2 dwg
