柱塞的长度总大于它的冲程，并只有柱塞的一个端面为液体增压。双作用柱塞泵至少需要两个缸体和柱塞。
A plunger is always longer than its stroke and only one end is available for pumping. Double-acting plunger pumps require at least two cylinders and plungers.
就针对如何降低泵的噪声问题，本人设计出了一种新型的低噪声双作用径向柱塞泵。
Aiming at how to reduce the pump noises, a new type of double acting piston radial pump with lower noises is designed here.
介绍了一种新型手动双作用双级柱塞泵的工作原理，给出了其排量与输出压力的计算公式。
