    • A pneumatically powerable single action fluid pump has a housing, an improved diaphragm assembly dividing the housing into fluidly discrete propellant and pumping chambers, a fluid inlet and outlet in the pumping chamber, a fluid port to the propellant chamber and a spring motor biasing the diaphragm assembly in a direction away from the pumping chamber side of the housing; the diaphragm assembly includes a perforate rigid diaphragm plate, an elongate motor stem connected to the plate, a contiguous elastomeric diaphragm having an imperforate front layer covering a front side of the plate and stem, a rear layer on a rear side of the plate, pins in the plate perforations and between and adjoining the diaphragm layers, and a bellows section to the outside of the plate. The spring motor biases the diaphragm to a position in close proximity to the fluid port of the propellant chamber in the absence of propellant therein against a plurality of spacer ribs. The spacer ribs permit an even and rapid distribution of propellant into the propellant chamber to drive the diaphragm assembly against the biasing action of the spring motor toward the pumping chamber.
    • 气动功率单动液体泵具有壳体,改进的隔膜组件,将壳体分为流体分离的推进剂和泵送室,泵送室中的流体入口和出口,到推进剂室的流体端口和偏置隔膜的弹簧马达 在远离壳体的泵送室侧的方向上组装; 隔膜组件包括穿孔刚性隔膜板,连接到板的细长马达杆,连续的弹性膜片,具有覆盖板和杆的前侧的无孔正面层,板后侧的后层 在板状穿孔中并且隔膜层之间和隔膜层之间,以及到板外侧的波纹管部分。 在没有推进剂的情况下,弹簧马达将隔膜偏压到靠近推进剂室的流体端口的位置,以抵抗多个间隔肋。 间隔肋允许推进剂均匀且快速地分配到推进剂室中,以驱动隔膜组件克服弹簧马达朝向泵送室的偏压作用。
