Abstract (en)

[origin: EP0371841A1] The present invention relates to a cooling circuit for an internal- combustion engine of a motor vehicle. The circuit is characterised in that the downstream end part of the pipe (18) opens out downstream of the thermostat (19), and a member forming a shutter is arranged at one of the ends of the pipe (18) and opens when the vacuum at the inlet of the pump (6) reaches a threshold value slightly below a vacuum value causing a cavitation of the liquid. The present invention is used particularly for diesel engines. <IMAGE>
