The experimental results show that the loss factor and damp ratio decrease, the resonance frequency increases with increase of the aperture of the piston in the damper.
对阻尼器不同孔径进行了对比试验，试验结果表明：随着活塞孔径的增大，阻尼器的损耗因子和阻尼比减小，共振频率增加。
Complete air piston pump contains pneumatic motor and piston pump, the ratio of piston area of pneumatic motor and plunger ' s sectional area of piston pump is transforming times of pump pressure ;
完整的气动柱塞泵包含有气动马达与柱塞泵两部分，气动马达中的活塞面积与柱塞泵活塞的截面积比值，就是泵压力转换的倍数； 愈高的倍数就能以愈大的压力输送愈高黏度的流体，达到输送的目标。
