The engine, as it cooled itself, sucked in air through the outlet hose, producing suction in the vacuum chamber, and so drawing the plunger down and compressing the spring.
当引擎冷却时，通过出口软管吸入空气，在真空管产生吸气，导致柱塞向下挤压弹簧。
Upward motion of the buoy causes a suction which lifts the balls, thus allowing air to be drawn back down the counterweight tube.
浮标的向上运动则产生吸力，可将阀球提起，这样可允许气流受力并返回至配重管。
Those parameters included pull down speed and power consumption of the refrigerator, temperature of cold storage chamber, freezing chamber, condenser, suction and discharge pipes of compressor, etc.
这些参数包括冷却速度、耗电量、冷藏室温度、冷冻室温度、冷凝器温度、压缩机吸气温度和排气温度等。
