    • A reservoir in which coolant is stored, is fluidly interposed between the downstream end of the condensor in which coolant vapor from the engine coolant jacket is condensed, and a coolant return pump which is responsive to a level sensor disposed in the coolant jacket, in a manner to form part of the cooling circuit of the system. The system further includes two temperature sensors, the first is disposed in the lower tank of the radiator and the other in the coolant jacket proximate the cylinder head. A device which modifies the pressure prevailing in the system is operated in response to one or both of the temperature sensors. This device can take the form of a cooling fan or an electromagnetic valve which controls one of a coolant jacket/atmosphere vent or a reservoir/atmosphere vent.
    • 存储冷却剂的储存器被流体地插入在冷凝器的下游端之间,冷凝器的下游端在其中来自发动机冷却剂套的冷却剂蒸气被冷凝,冷却剂回流泵响应于设置在冷却剂套中的液位传感器, 以形成系统的冷却回路的一部分。 该系统还包括两个温度传感器,第一个设置在散热器的下槽中,另一个设置在靠近气缸盖的冷却剂护套中。 响应于一个或两个温度传感器来操作改变系统中存在的压力的装置。 该装置可以采取冷却风扇或电磁阀的形式,其控制冷却套/大气排放口或储存器/大气排放口之一。
