Abstract (en)

[origin: EP0731261A1] The circulation pump (3) drives coolant through the engine (1) to a heat exchange module (2) in the stream of air drawn by a fan (4). The speeds of the pump and fan are adjusted by a set-point controller (5) connected to a temp. sensor (11) at the outlet from the engine. Other branches of the coolant circuit between the engine and pump pass through a pressure-balancing reservoir (7), a vehicular interior heater (8), and engine and transmission oil coolers (9,10), to be recombined at a temp.-dependent valve (6) operated by signals from the controller.
