Abstract
A dosing unit for highly filled synthetic-resin components, usually a polyol and an isocyanate mixed with glass fiber, barite or chalk, comprises a piston which displaces the components or one of them, especially the filled component, under the control of fluid pressure. The change in the feed rate of the fluid-controlled unit is varied by varying the speed of the displacing member of the fluid-controlled unit which is preferably a piston-and-cylinder arrangement or a membrane or diaphragm-type displacement device.
