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。

To this end, it is detected from the simulation results that the equivalent valve damping length and decompressing chamber volume significantly affect the outlet pressure.

分析结果表明：阀内流道的等效阻尼长度和压力反馈腔体积是影响阀出口压力的重要因素。
