    • A liquid cooling circuit for driving and working engines, in particular for internal combustion engines, contains, in an ancillary flow vent pipe (14), an air extraction container (17) arranged at the tip (5') of the cooler lead-in (5). A filling pipe (19) with correcting ports (5'' and 17') for the cooler lead-in (5) and air extraction container (17) contains a sealing cover (20) which seals these connecting ports from each other. Overpressure, underpressure and vent valves (21 and 22) in the sealing cover (20) control a connecting line (25) to an atmospheric or overpressure equalizing container (27). The connecting line (25) which is opered at least at low coolant temperatures by a thermostatically controlled vent valve (22), permits highly efficient ventilation associated with a marked variation in engine speed. As a result of the arrangement and the low-volume of the air extraction container (17), filling is more rapid and the engine (1) warms up more quickly. Advantages resulting from other features of the invention are compact design, reduction of cost and weight, component compatibility, and extended operating conditions of the cooling circuit to ensure optimal cooling.
    • 用于驱动和加工发动机,特别是用于内燃机的发动机的液体冷却回路在辅助流通管(14)中包含设置在冷却器引入件的尖端(5')处的空气提取容器(17) (5)。 具有用于冷却器引入件(5)和空气抽取容器(17)的校正端口(5“和17”)的填充管(19)包含密封这些连接端口彼此的密封盖(20)。 密封盖(20)中的超压,负压和排气阀(21和22)将连接管线(25)控制到大气压力或超压均衡容器(27)。 通过恒温控制的排气阀(22)至少在低冷却剂温度下被打开的连接管线(25)允许与发动机转速明显变化相关联的高效通风。 作为空气抽取容器(17)的排列和体积小的结果,填充更快,发动机(1)更快地变暖。 由本发明的其它特征产生的优点是紧凑的设计,降低成本和重量,部件兼容性以及冷却回路的延长操作条件以确保最佳冷却。
