Apparatus for the metered discharge of a plurality of part-quantities of viscous substances, such as casting resin

摘要

An apparatus for the metered discharge of a plurality of part-quantities of viscous substances, such as casting resin, under vacuum or under pressure is described, with a device for preparing and discharging the viscous substance, preferably comprising two or more resin components which react together with curing, to a metering pump (50) the outlet opening of which is arranged within a vacuum or low pressure chamber (48) above receptacles (56) for the part-quantity of viscous substance. According to the invention a plurality of identically constructed metering pumps (50) are provided which are arranged adjacently and can be actuated via a common actuation bridge (52) which, via a branching device (38), are arranged downstream of the preparation device (10) for preparing and discharging the viscous substance, the branching device (38) constituting a manifold arranged parallel to the row of metering pumps and having a separate non-return valve (80) for each metering pump (50).
