    • Components are provided for use in systems for dispensing fluids. A resilient diaphragm (34) is provided for a diaphragm pump (30). The diaphragm (34) includes a pressurizing portion (52) and annular base wall (54) connected with a connecting member (58) to a peripheral mounting flange (60) for mounting the diaphragm (34) in the housing (32) of the pump (30). The pump housing (32) has a retention wall (70) which can be swaged against the diaphragm flange (60). The pump housing (32) has a discharge structure (36) with an outlet valve (38) and a restraint structure (130, 132) adjacent the valve (38) to prevent in-venting through the outlet valve (38). The outlet valve (38) includes a flange (160) which is retained by a retention wall (120) and which projects from the discharge structure (36) and which is swaged into engagement with the outlet valve flange (160).
    • 提供组件供在分配流体的系统中使用。 为隔膜泵(30)提供弹性隔膜(34)。 隔膜(34)包括与连接构件(58)连接到外围安装凸缘(60)的加压部分(52)和环形底壁(54),用于将隔膜(34)安装在外壳 泵(30)。 泵壳体(32)具有保持壁(70),该保持壁能够抵靠膜片凸缘(60)而被锻造。 泵壳体32具有排出结构36,排出结构36具有排出阀38和邻近阀38的约束结构130,132以防止通过排出阀38进入。 出口阀(38)包括由保持壁(120)保持并从排出结构(36)突出并与出口阀凸缘(160)相啮合的凸缘(160)。
