ABSTRACT:
An apparatus for metering out viscous compositions includes a metering chamber (12) for metering out the viscous composition, a driving mechanism (16), which drives a displacer disposed in the metering chamber, an inlet valve (32), which is connected upstream from the metering chamber (12) and an outlet valve (38), which is connected downstream from the metering chamber (12) and, after the metering chamber (12) is filled, is opened up for discharging the metered-out viscous composition from the metering chamber (12). A threaded rod (14) is disposed longitudinally displaceably as displacer in the metering chamber (12). The threaded rod (14) is rotationally guided coaxially in a hollow shaft (18) of an electric motor (16) and engaged by way of threads with the hollow shaft (18).
