Abstract
A water-cooled internal combustion engine includes piping defining a hydraulic oil circuit having an oil pump and using hydraulic oil lubrication and a cooling-water pump driven as a function of the operating condition of the engine. The hydraulic motor is provided in the circuit for the drive of the cooling-water pump which, by means of a control element, can be switched into the hydraulic oil circuit of the internal combustion engine.
