A seal is provided between the plunger and barrel to prevent air from passing into or out of the barrel around the plunger and through the plunger end.
在柱塞和针筒之间具有密封件,以防止空气进入或跑出柱塞周围的针筒以及穿过柱塞端。
The plunger in the fully depressed position releases the needle carrier from the end of the barrel and the vacuum pulls the needle carrier and needle into the hollow plunger.
柱塞在完全压下的位置将针头座子从针筒的端部释放,真空将针头座子和 针头推入空心柱塞。
Bias-plunger and bias-spring systems are less aggressive, and subsequently deliver a less consistent, yet still acceptable, connection between plunger and barrel.
偏置顶针和偏置弹簧系统的积极性较低,因而在顶杆和套筒之间提供一致性较低但仍可接受的连接。
The bias-ball system is the most aggressive, providing a highly consistent connection between the plunger and barrel by compressing a ball against an angled plunger.
偏置球系统最有积极性,通过将球压到一个倾斜的顶杆,在顶针和客体之间提供极其一致的连接。
R2 is the point of signal transfer between plunger and barrel.
R2是顶针与套壳体之间的信号传输点。
A protrusion (56) forming a ridge is disposed on one of the roof of the barrel and the plunger head.
形成脊的突起(56)设在注射筒顶部和柱塞头中的一个上。
The relatively smaller cross section of the plunger as compared to the barrel produces a corresponding greater vacuum force.
柱塞与针筒相比相对较小的横截面产生了相应的较大的真空力。
The calculating equation of the relative rotating Angle in the leakage test of plunger and barrel assembly has been deduced by the geometric method.
利用几何方法推导柱塞偶件密封性试验中相对回转角度的计算式。
The device includes a plunger sized to extend into the barrel member.
该装置包括尺寸设计成伸入管状构件的柱塞。
As the plunger is depressed to inject the fluid the plunger moves axially in the barrel while the piston is stationary.
当柱塞被压下以注射液体时,柱塞在针筒内作轴向运动,而活塞则是固定的。
A plunger (24) having an elongate body portion and a stopper (54) slidably positioned in fluid-tight engagement with the inside surface of the barrel is provided.
配置具有拉长主体部分和止动件(54)的柱塞(24),所述止动件以与针筒内表面液密啮合的方式滑动定位。
The barrel is open at both ends to receive a plunger at the plunger end and a needle at the opposite end.
针筒两端都开口,以在柱塞端收容柱塞并在相反端收容针头。
