    • The proposed apparatus comprises two chambers (7 and 12) conected by a baffle separator (9) and provided with pistons (8 and 11) that operate alternately to intimately mix the components, then simultaneously to feed the mixture obtained into a mold. Upstream of the mixing chambers (7 and 12) a recirculation circuit is provided for each component, connected to one of the chambers by means of a three-way valve (6) preferebly having a plunger shutter so that it can alternately control feeding or recirculation of each component in the reaction. Recirculation of the material preferably takes place under low pressure: from 1 to 15 bars at the most. The mixing and feeding pressure is preferably maintained at 100-300 bars. The pistons of the mixing chambers (7 and 12) are preferably equipped with piston rings.
    • 所提出的装置包括一个由挡板式分离器(9)和设置有活塞(8和11)做了操作交替地紧密地混合各组分,然后同时向混合物送入获得的模具conected两个腔室(7和12)。 上游通过三通阀(6)preferebly具有柱塞快门所以这样做是可以替换地控制供给或再循环的装置,用于每个组件的再循环回路中的混合室(7和12),连接至所述腔室之一的 在反应的每个组分。 该材料的再循环优选发生在低压下:从1到15巴至多。 混合和进给压力优选维持在100〜300巴。 混合室(7和12)的活塞优选地装备有活塞环。
