Abstract (en)
[origin: US4834029A] A cooling circuit (5) for an internal combustion engine in which a throttle (2) is provided upstream of a heat exchanger (10, 11). The throttle (2) equalizes the oil pressure in the internal combustion engine in front of the heat exchangers and insures that this occurs almost independently of the temperature of the oil. By this provision, the heat exchangers can be fabricated with the least expense since the danger of bursting is reduced.
