摘要： A pre-compression pump sprayer has a spring biased discharge poppet valve element with a seal in engagement with the wall of the piston stem, a seal interruption to establish a discharge valve open position, and an upstream directed throttle valve presenting a two-stage pressure build-up discharge valve establishing a predetermined pressure threshold which when exceeded by fluid pressure generated in the pump chamber during pumping immediately opens the throttle valve and abruptly releases the fluid pressure at the valve open position. The valve has an elongated probe extending into the pump chamber of an extent as to shift the poppet valve open upon engaging the inlet check valve upon a full downstroke of the piston for evacuating air from the pump chamber out through the discharge orifice to effect pump priming. During pumping operation, product is sucked back from around the discharge orifice into the discharge passage at the commencement of the piston suction stroke as the discharge valve remains momentarily open. An inlet check valve has a center of gravity located upstream of its valve seat to assure accurate seating of the inlet valve during pump operation at angles tilted from upright. And, a dry piston return spring is optionally provided, as is a diametral container vent seal.
摘要翻译：预压泵喷雾器具有弹簧偏压的排出提升阀元件，其具有与活塞杆的壁接合的密封件，用于建立排放阀打开位置的密封件中断和呈现两级压力的上游定向节流阀建立排出阀，其建立预定的压力阈值，其在泵送期间在泵室中产生的流体压力超过时立即打开节流阀并突然释放阀打开位置处的流体压力。阀具有延伸到泵室中的细长探针，其程度在使活塞完全向下冲程时接合入口止回阀时使提升阀打开，以将泵从泵室排出通过排出孔，从而实现泵启动。在泵送操作期间，当排出阀暂时打开时，在活塞吸入冲程开始时，产品从排放口周围被吸回排放通道。入口止回阀具有位于其阀座上游的重心，以确保在泵操作期间入口阀在垂直方向倾斜时的准确安置。并且，可选地提供干式活塞复位弹簧，如直径容器通风口密封。

摘要： An anti-clog pump sprayer has a cover mounted for independent reciprocation on a plunger head, the cover having a cupped spring biased portion covering the discharge orifice on the head to avoid clogging on product drying, and being lifted off the orifice during the relative shift for uncovering the orifice in readiness for spraying. The sprayer may also have a product retraction device on the plunger head in communication with the discharge orifice, a projection on the underside of the cover top wall for actuating the device at the commencement of the plunger return stroke for creating a slight sub-atmospheric pressure for suctioning any residual product inwardly of the orifice to thereby avoid clogging.

摘要： A manually actuated pump dispenser has a water seal for maintaining the container vent ports sealed closed during pumping until at or near the end of the pressure stroke whereupon a vent path through which only air is permitted travel into the container, is open as the path is shielded against water entering the vent path when pumping in a wet environment as when dispensing hair shampoo or hair conditioner. In a plunger lock-down position of shipping and storage, leakage of product through the vent ports is substantially avoided during a superatmospheric condition within the container.
摘要翻译：手动启动的泵分配器具有水密封，用于在泵送期间将容器通气口保持密封关闭，直到压力行程结束时或接近压力行程的结束，因此仅允许空气通过的排放路径行进到容器中，因为路径是当在潮湿的环境中泵送时，当分发头发洗发水或护发素时，防止水进入通气路径。在运输和存储的柱塞锁定位置中，在容器内的超大气压条件下，基本上避免了通过排气口泄漏产品。
