    • Inside a syringe (1) slides a piston (2) which carries a seal (4) which sealingly slides on the internal wall of the syringe. The flexible membrane (6) of the seal (4) fixed at the extremity of the piston (2) carries an obturation part (25, 27) which follows the deformation or displacement motion of said membrane under the effect of the pressure generated during the injection phase but which is retained by blocking lamellae (17) in a position where it opens the orifice by braking the seal between the top and the bottom of the seal as soon as the membrane returns to its initial position. Application to medicine.
    • 在注射器(1)内滑动一个活塞(2),该活塞带有一个在注射器的内壁上密封滑动的密封件(4)。 固定在活塞(2)末端处的密封件(4)的柔性膜(6)承载着密封部分(25,27),其在所述膜的产生的压力的作用下跟随所述膜的变形或位移运动 注射阶段,但是通过在薄膜返回到其初始位置时通过将密封件的顶部和底部之间的密封制动来打开孔口的位置,通过阻挡薄片(17)而被保持。 适用于医药。
