它是一款非常小巧的真空管，形状和大小如浴缸塞，内含一个柱塞和弹簧，由两个小型空气软管连接。
2·Using constant pressure variables plunger pump, output pressure can keep constant and flow varies as per system's demand.
采用恒压变量柱塞泵，输出压力保持恒定，输出流量根据系统需要而变化。
3·The balance valve circuit is to support the weight of platen and plunger design.
回路中的平衡阀是为支撑压板及柱塞的重量而设计的。
4·One effective way is preferred pump barrel and plunger of materials and surface treatment processes.
其中一个有效的方法就是优选泵筒和柱塞的材料和表面处理工艺。
5·Unlike compression molding, however, transfer molding includes heating the plastic to a fluid state before it gets to the mold and forcing it into a closed mold using a hydraulically actuated plunger.
与压缩成型，但是，传递模塑包括取暖的塑料流体之前得到国家的模具，并迫使它变成一个封闭的模具采用液压驱动柱塞。
