正确答案

1)包括:空压机、储气筒、调压阀、安全阀、进气滤清器、排气滤清器、管道滤清器、油水分离器、空气干燥器、防冻器、多回路压力保护阀等装置。
2)作用:
(1)空压机:制造用以制动的压缩气体。
(2)储气筒:用以储存压缩空气,以保证实现随时制动。
(3)调压阀及安全阀:保证储气筒内压力在规定范围之内,既要保证正常制动,又要防止储气筒被胀破。
(4)进气滤清器、排气滤清器及管道滤清器:以清洁空气,避免灰尘、杂质等进入制动系统,减轻磨损,提高制动系统零部件的使用寿命。
(5)油水分离器:用以将压缩空气中的水分和润滑油分离出来,以免腐蚀储气筒及管路中不耐油的橡胶件。
(6)空气干燥器:由油水分离器输出的空气难免含有少量的水分,用干燥器将其干燥,以免腐蚀储气筒及管路中的其他金属器件。
(7)防冻器:防止在寒冷季节时,积聚在管路和其他气压元件内的残留水分冻结,而堵塞管路,保证正常制动。
(8)多回路压力保护阀:在多回路制动系中,当一套回路损坏漏气时,多回路压力保护阀能保证其余完好回路继续充气。
3)这些元件对于正常的气压制动系来说都是必不可少的。
