Abstract: A fluid pump dispenser includes a dispenser trigger which may be located in pivotable engagement with the dispenser housing and pump piston after shipment. The initial actuation of the trigger moves the pump piston and a container conduit, engaged thereto, to open a container vent shipping seal provided by mating surfaces on the conduit and the container cap. Fluid carried from the container by the conduit enters the pump chamber through a central orifice in the piston. A flexible member located on the piston functions as an inlet check valve for the conduit and as a piston ring. The fluid dispenser also includes a nozzle structure having a flexible member which functions as an outlet check valve and O-ring seal, and which cooperates with a threaded nozzle cap to vary the discharge pattern of the dispenser responsive to twisting adjustment of the cap.

Abstract translation: 流体泵分配器包括分配器触发器，其可以在出货之后位于与分配器壳体和泵活塞枢转接合。 触发器的初始致动使泵活塞和与其接合的容器导管移动以打开由管道和容器盖上的配合表面提供的容器通风口运输密封件。 通过管道从容器携带的流体通过活塞中的中心孔进入泵室。 位于活塞上的柔性构件用作导管的入口止回阀和活塞环。 流体分配器还包括具有柔性构件的喷嘴结构，该弹性构件用作出口止回阀和O形密封圈，并且其与螺纹喷嘴盖配合以响应于帽的扭转调节来改变分配器的排出模式。
