    • A combination gravimetric and volumetric fluid dispenser is disclosed which includes a scale (15) linked to a controller (21). The controllar is linked to a plurality of two stage valves (14) which control the dispensing of larga quantities of base materials. The controllar is also linked to a plurality of nutating pumps (34) which together with the controllar controls the dispensing of smallar quantities of additive materials. The dispensing system dioclosed is particularly useful for paints or other liquid formulations where larger quantities of base materials are added and which can be added br weight and whereby precise measurements of the larger base materials is not particularly required. However, the incorporation of nutating pumps and the addition of smallar amounts of additives by volume using the nutatïng pumps enables precise dispensing of the additives, such as colorants for paint. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus. The dispensing apparatus is also preferably designed with a modular configuration as shown and described. For viscous materials, an improved dispensing rnethod is disclosed whereby viscous base material is added to the container first followed by smaller amounts of additives followed by additional dispensing of viscous base materials. By sandwiching the smallar amounts of additives between layers of base materials, an improved mix ability results for viscous materials such as base materials of paints and colorants.
    • 公开了一种组合重量和体积流体分配器,其包括连接到控制器(21)的标尺(15)。 控制器连接到多个控制大量基材的分配的两级阀(14)。 控制器还连接到多个章动泵(34),其与控制器一起控制少量添加剂材料的分配。 二次闭合的分配系统特别适用于添加更多量的基础材料并且可以加入的涂料或其它液体制剂,并且因此不特别需要对较大基材的精确测量。 然而,使用营养泵并入章动泵和体积小量的添加剂可以精确分配添加剂,如涂料着色剂。 较大的基材的容器或容器可以设置在远离分配装置的位置。 分配装置还优选地被设计成具有如所示和描述的模块化配置。 对于粘性材料,公开了一种改进的分配方法,其中首先将粘性基材添加到容器中,然后加入较少量的添加剂,然后再额外分配粘性基材。 通过将少量的添加剂夹在基材层之间,改进的混合能力可以产生粘性材料,如油漆和着色剂的基材。
