    • A power assembly for dispensing product from a container includes a pump mechanism and an energy storage mechanism. The pump mechanism includes a rotatable actuating collar connected through an escapement mechanism with a drive screw with an externally threaded shaft engaged with internal threads in a piston. Rotation of the collar reciprocates the piston to store energy in the energy storage mechanism and to draw product into a pump chamber from which the product is dispensed. An actuator is connected with a stem valve to open it when the actuator is depressed, enabling the energy storage mechanism to push the piston back to its at-rest position to force product from the pump chamber and ready it for another dispensing cycle. Disengagement of the escapement mechanism when the actuator is depressed prevents rotation of the actuating collar. Different energy storage mechanisms can be interchangeably attached to the pump mechanism.
    • 用于从容器分配产品的动力组件包括泵机构和能量储存机构。 泵机构包括通过擒纵机构与驱动螺杆连接的可旋转的致动套环,其中外螺纹轴与活塞中的内螺纹接合。 套环的旋转使活塞往复运动,以将能量储存在能量存储机构中,并将产品吸入泵室中,从中分配产品。 致动器与杆阀连接以在致动器被压下时将其打开,使得能量存储机构能够将活塞推回到其静止位置以迫使来自泵室的产品准备好用于另一个分配循环。 当致动器被压下时擒纵机构的脱离防止了致动套环的旋转。 不同的储能机构可以互换地连接在泵机构上。

    • A medicament-dispensing system includes a cartridge for housing and actuating an accordion-like vial-dispenser for dispensing a calibrated amount of medicament by means of a single actuation motion which sequentially loads the vial-dispenser and dispenses the loaded medicament. The vial-dispenser has a front bellows portion, a rear bellows portion, an internal piston mechanism, a medicament storage chamber and a dosage cavity. The cartridge has a trigger mechanism which acts in concert with a notched lever and a wedge-shaped arm internally located in the cartridge to sequentially load the dosage cavity with medicament and discharge it. Depression of the trigger mechanism simultaneously extends, by means of the notched lever, the front bellows portion and compresses the rear bellows portion to load the dosage cavity with medicament. Once the notched lever has extended the front bellows portion a predetermined distance, the notched lever is disengaged from the front bellows portion by the wedge-shaped arm extending from the rear wall of the housing, thereby releasing the front and rear bellows portions, along with the internal piston mechanism, to return to original position and force the medicament from the dosage cavity via a nozzle of the vial-dispenser.
