    • A manual precompression pump for spraying or dispensing a fluid substance contained in a receptacle, said pump having a pump body (1) in which a hollow piston (2) slides the piston being extended by a hollow rod (3) including the seat (7a) for a closure valve member (6) urged towards said hollow rod by a spring (10), said spring pushing the valve member (6) and the piston (2) towards a rest position, said pump including a pump chamber (12) which is in communication with the receptacle when the valve member and the piston are in their rest positions, said pump chamber (12) being capable of being isolated from the receptacle by sealed interfitting of a first cylinder (8) integral with the valve member (6) and of a second cylinder (4) integral with the pump body, said pump being characterized in that a valve rod (7b) extends the valve member (6) through the hollow rod (3) to a distance H1 beyond the outside end of the hollow rod, and in that starting from the rest position of the valve member, the cylinder (8) integral with the valve member can be moved towards the cylinder (4) integral with the pump body through a distance H2 which is greater than H1 without the interfitting between the two cylinders becoming sealed.

    • A prior art precompression metering pump which incorporates a differential piston forming part of the pump chamber inlet valve and its outlet valve is difficult to prime, especially in the case of metering paste products. In the improved pump there is disposed between the differential piston and the main piston of the pump a collar consisting of a ring from which project substantially axial tongues which are slightly inwardly inclined and each provided with a head. The collar moves inside the pump body so that normal operation proceeds as if it were not present. To prime the pump, however, the user depresses the collar until it contacts a step on the pump body. The tongues then bend so that their heads, interposed between the two pistons, move the latter apart (by a wedging effect or by a lever arm effect, or by a combination of the two). This is followed by mechanical opening of the pump chamber outlet valve whereby the air initially contained in the pump chamber escapes to the exterior.
    • 结合形成泵室入口阀和其出口阀的一部分的差动活塞的现有技术的预压计量泵尤其难以填充,特别是在计量浆料产品的情况下。 在改进的泵中,在差动活塞和泵的主活塞之间设置有由环组成的套环,该环从该环突出大致轴向的舌状物,其稍微向内倾斜并且各自设置有头部。 轴环在泵体内移动,使得正常操作如同不存在一样进行。 然而,为了灌注泵,用户按压套环直到其接触泵体上的台阶。 然后,舌头弯曲,使得它们的头部插入在两个活塞之间,使它们分开(通过楔形效应或杠杆臂效应或两者的组合)移动。 之后是泵室出口阀的机械打开,由此最初容纳在泵室中的空气逸出到外部。

    • The present dispenser device is designed in particular for eye treatment and comprises a pump body including a pump chamber, a piston slidable within the chamber and extended beyond the chamber by a rod pierced by a channel capable of communicating with the chamber, and an endpiece fixed to the rod and having a dispensing orifice in line with the channel of the rod. In addition to the above conventional items, the dispenser has a chamber admission valve which is constituted by co-operation between the enclosure defining the pump chamber and the piston which engages therein or projects therefrom as the case may be. The co-operation is preferably via a sealing lip. This disposition makes it possible to dispense a drop whose volume as determined by the capacity of the chamber is very small. In addition, the piston is returned to its rest position with the admission valve closed by resilient means disposed between the pump body and the endpiece. This guarantees that only drop is dispensed at a time. Finally, an outlet valve is placed between the end of the channel in the rod and the dispensing orifice of the endpiece in order to ensure that a dispensed drop is slightly precompressed. The dispenser device is advantageously integrated in a dispenser assembly comprising a supply of substance to be dispensed together with a housing facilitating actuation of the assembly by a user. Some designs of assembly are particularly attractive, from the economic point of view, with respect to the process of being filled with the substance to be dispensed.
    • 本发明的分配装置特别设计用于眼睛治疗,并且包括泵体,泵主体包括泵室,可在腔室内滑动的活塞,并且通过能够与腔室连通的通道刺穿的杆延伸到腔室之外, 并且具有与杆的通道一致的分配孔。 除了上述常规项目之外,分配器具有腔室进入阀,其通过在限定泵室的壳体和接合于其中的活塞或根据情况可能从其突出的活塞之间的协作而构成。 合作优选经由密封唇。 这种配置使得可以分配由腔室的容量确定的体积的液滴非常小。 此外,活塞返回到其静止位置,入口阀由设置在泵体和端件之间的弹性装置关闭。 这样可以保证一次只能下降。 最后,出口阀被放置在杆中的通道的端部和端部件的分配孔之间,以确保分配的液滴被稍微预压缩。 分配器装置有利地集成在分配器组件中,该分配器组件包括要被分配在一起的物质的供应物,以便于用户对组件的致动。 从经济的观点来看,一些装配设计特别有吸引力,就是要填充待分配物质的过程。
