ABSTRACT:
A lubricating system for an internal combustion engine maintains lubrication even in extreme emergency positions of the engine such as slants within the range of about 90.degree. to about 270.degree., relative to the horizontal and even for upside down engine positions. For this purpose, a hydraulic accumulator (16) is connected to the lubricant circulating circuit through a parallel connection of a non-return valve (17) and a controllable valve. Under normal operating conditions, the hydraulic accumulator is charged with lubricant under the pressure prevailing in the lubricant circulating system. Under emergency conditions, the normal lubrication is stopped and emergency lubrication continues through the controllable valve that is opened in response to a pressure drop in the normal lubricant circulating system.
