摘要： A fluid dispensing piston for a cylindrical dispensing tube has a recessed transverse end wall formed with at least one aperture. The aperture is normally covered by a fluid seal removably retained on the exterior surface of the end wall. The piston is placed in a cylindrical dispensing tube with the exterior of the end wall pressing against the fluid in the tube and the piston is moved axially down the tube to dispense the fluid. Further fluid may then be added to the tube and a second piston moved axially down the tube to dispense that fluid, the conformable material covering the aperture in the end wall of the first piston being forced away from the end wall to uncover the apertures as the second piston is moved down the tube to create a pathway for the fluid through the first piston.
摘要翻译： 用于圆柱形分配管的流体分配活塞具有形成有至少一个孔的凹入的横向端壁。 孔通常由可移除地保持在端壁的外表面上的流体密封件覆盖。 活塞被放置在圆柱形分配管中，端壁的外部压靠管中的流体，并且活塞沿着管轴向移动以分配流体。 然后可以将另外的流体添加到管中，并且第二活塞沿管子轴向移动以分配该流体，覆盖第一活塞的端壁中的孔的适形材料被迫远离端壁以露出孔，如 第二活塞向下移动，以产生通过第一活塞的流体的通路。
